They were the first graduates of the Singapore Polytechnic School which accepted its first students in 1959. He registered as an Architect in 1965, the year Singapore seceded from Malaysia . A major influence in his formative years at the Polytechnic was Lim Chong Keat, a dynamic young graduate of Manchester University and MIT, who was a partner with William Lim Siew Wai and Chen Voon Fee in the practice of Malayan Architects Co-Partnership formed in 1962. Lim Chong Keat left a strong impression of architectural integrity based on attitudes formed while at MIT. The ethics of the Bauhaus; the idea of hands-on experience and verbalising the process of architecture were conveyed to Lim Chong Keat by Gyorgy Kepes, and Tay strongly inbibed the Bauhaus tradition through Lim Chong Keat.

Lim Chong Keat taught for two years in the Polytechnic and Tay worked for him on a house in Binjai Park. Another teacher who greatly stimulated Tay and remains a close friend and provocateur is Lee Kip Lin. Tay's 'Malayanism' was strongly influenced by both men. Two particular buildings were an inspiration to Tay at that time. One was the Singapore Conference Hall and Trade Union House, the

formative architectural education in Singapore. It is significant for although the Singapore system was, and still is, largely modelled on the British educational model, it perhaps set Tay apart from the overseas graduates returning from Australia, UK and the USA.

Tay was one of the first post-colonial architects not to have worked in one of the prominent expatriate practices such as those of Swan and Maclaren, James Ferrie and Partners, Raglan Squire and Partners, and Palmer and Turner. In 1966, Tay embarked on a world study tour to further his education armed with letters of introduction to the friends of Lim Chong Keat and William Lim around

the world. He recalls that the intensity of light in the architecture of Ram Karmi, an Israeli friend of William Lim, made a particularly strong impression upon him that was to have an affect on his own architecture as was the notion of interlocking geometries in the work of Alfred Neumann at Haifa University.

In 1967, the Malayan Architects Co-Partnership was dissolved. Chen Voon Fee worked out of Kuala Lumpur (the Malaysian capital), Lim Chong Keat set up Architects Team 3, whilst Tay Kheng Soon along with Koh Seow Chuan (another Associate) joined William Lim as founding partners of Design Partnership (the forerunner of the now huge corporate practice DP Architects Pte Ltd). Lim's influence on the practice's direction was very strong. The practice was in its Brutalist phase; a response to the demands for an architecture to express the confidence and determination of the new nation. Tay worked with William Lim on the design of the Tanglin Shopping

Centre (since (de)faced in marble and aluminium cladding), Katong Shopping Centre and People's Park Complex (1967-70) in Singapore's Chinatown. The latter was inspired by the interlocking geometries in thework of Alfred Neumann and by Fumihiko Maki's work on Collective Form whilst a Visiting Professor at MIT. Lim recounts in his book Cities for People how Maki visited the site during construction and commented that," We theorised and you people are getting it built..."

All architecture is political.
All action, everything, unless you are blind.
Even the pretence that architecture is not political, is itself a political act.

In the early years of independence, the country was going through profound political and social changes. The Housing and Development Board was set up in 1960 as well as the Urban Renewal Department (later renamed Urban Redevelopment Authority). Architects and academics were naturally caught up in issues of housing, urban planning and the environment.

In 1964, a number of architects and other professionals formed an independent think-tank with the acronym SPUR (Singapore Planning and Urban Research Group). Tay was among the more outspoken of the group. In 1966, he published an essay in Rumah, the Journal of the Singapore Institute of Architects entitled 'Public Housing in Singapore' and in September 1967, in a paper delivered to the Democratic Socialist Club at the University of Singapore entitled 'Environment and Nation Building', he expressed apprehension about the housing policies adopted by the government. At the time, less than 35% of Singaporeans were accommodated in public housing but Tay, alert to the potential problems of monotony, identity and lack of a sense of community, called for opportunities for people to participate in the building of their homes in the form of co-operative housing. Concerned with the shortage of land in the city-state, he advocated that, "We should build compact high-density; medium-rise housing in which it is possible to create viable communities"(Tay 1967). It was a theme that he was to pursue passionately over the following thirty years. The process of (un)learning was already discernable.

He enlarged on this theme two years later in October 1969 in a paper presented at a SPUR seminar on 'The Planning and Development of New Urban Centres'. Using Jurong as a case study, he put forward the notion of planned proximity of residence and employment together with the decentralisation of hospitals, schools and other social amenities (Tay 1969). Implicitly, this was a criticism of the zoning policies of the government planning agencies and the planning models inherited from the British.

From 1970 to 1971, Tay was the Chairman of SPUR. SPUR offered numerous ideas, some of which gained acceptance. For example, it was SPUR who first proposed that the Singapore International Airport should be at Changi and not at Paya Lebar. But in a paper published in June 1970, in the organ of the University of Singapore Students Union, entitled 'Development and its Impact on Changing Values', Tay launched a hard-hitting attack on the quality of the built environment emerging from government agencies and what he saw as a decline in human sensitivities arising from the centralisation of decision-making at all levels. He sensed an alienation in society and a decline in intel-lectual integrity. "In an atmosphere of expediency as a basis for action," he noted, "each individual comes to terms with his own brand of self-deception." (Tay 1970)

With such critical views, SPUR was inevitably drawn into controversy. The government's patience with this criticism of Singapore's housing and urban planning policies eventually wore thin and the Group was 'dissolved' in 1973. Tay was outspoken on other issues, including Public Transport provision. A talk to the Singapore Rotary Club in September 1974 on public transportation systems, followed by a exchange of letters in the Straits Times, led to Tay being castigated by Lim Leong Geok, the then Secretary to the Road Transport Action Committee, who suggested he should stand as a candidate for election to Parliament if he desired answers to his questions. For Tay, modern architecture was simply inseparable from its social under-pinnings and this carried over into other fields.

R e t u r n f r o m E x i l e

Encouraged by the success of the housing projects, Tay returned from his self-imposed exile and in March 1976 set up Akitek Tenggara in Singapore with Chung Meng Ker. They were joined by Woo Tchi Poung who sadly died in 1982. Chung Meng Ker studied architecture at the National University of Singapore and worked for Design Partnership after graduating in 1973. He met Tay, who was a part-time tutor in the School of Archi-tecture, at a workshop on high-density low-rise housing and subsequently worked with him on the Cheras and Setapak Jaya low-income housing projects.

You must constantly ask the question, 'So what?' Asking the right questions is an important function of analysis."

This gives an insight into Chung's contribution to the practice. Patrick Chia says of him,"Chung Meng Ker excavates deeply and precisely within the confines of an archi-tectural problem to arrive at the most balanced solution; he weaves together finely dovetailed answers. His strength is in the detailed resolution of morphologies and a simultaneous ability to make connections at the highest levels." (Chia 1996)

"Architectural input into the planning process is important. Planning invariably assumes certain built forms; certain models. Architectural models are not questioned sufficiently. The URA and the HDB, for example, do not sufficiently question past models. They restrict possibilities by assuming the truth of past models; in effect they confirm their own assumptions. Land is chopped into certain sizes and it is assumed that only contractors of a certain size can handle them but if you generate different parameters, there may be different design solutions and different geometries may emerge." Chung says of his relationship to Tay and Chia," We share several things in common. We believe that we should deal with every design problem at a very fundamental level. We don't jump into style. We try to define the forces and then define the geometry that resolves these forces."

In 1982, Tay delivered a paper to the Australian Institute of Architects Conference (held in Singapore) entitled 'The Architecture of Rapid Development' in which he pointed out that, "the attitudes and ideals gained through the educational systems of more wealthy and stable societies are simply not applicable in the situation of rapid development being experienced by Singapore. For example, in the former, change is regarded as destructive; in the latter, change is regarded as a good thing: similarly, in the former, planning must be comprehensive whilst in the latter, ad-hoc action gets things done. The values of professionals trained in the traditional way may have to undergo considerable readjustment in order to function effectively in an environment of rapid development." Tay contributed a paper entitled 'Cultural Identity in Architecture as Perceived from a Singapore Viewpoint' at a seminar organised by the Aga Khan Award for Archi-tecture and the Malaysian Institute of Architects (PAM) in Kuala Lumpur in 1983. In his paper, he listed a number of key issues which should form the agenda for continuing discussion on a relevant architecture for Asia.

The issues highlighted were:
o The study of complex interlocking geometries of human settlements.
o The reconceptualisation of land-use planning aimed at giving vitality to city centres and housing estates.
o The proper integration of nature in architecture.
o The injection of a sense of grandeur in public spaces calculated to uplift the human spirit.
o The speed and rate of visible change and methods of building to cope with this phenomena.
o The use of shadow graduations and the celebration of tropical rainstorms in architectural elements.
o The insistence that the basic direction of the search for a Southeast Asian architecture must come from those committed to the internal dynamics involved.

In another 1984 paper entitled "Innovative Technology: Implications on the search for a relevant approach to Architecture", delivered at the Asian Congress of Architects, Tay drew attention to the contributions of Kisho Kurokawa to the intellectual debate on Asian architecture and stressed the need to question the Western thought process itself. Kurokawa analyses the bi-polar fixation in Western thought and suggests it be replaced by an Asian tri-polar viewpoint which defines a neutral zone between polar opposites: as the zone of maximum tension and therefore of creativity. "What we need," said Tay," is a new modernism, one which can include matters of the spirit and of the senses. The rich oriental traditions can be a source of inspiration for this new modernism and in the search for a dynamic balance of the complex and contradictory realities."

A year later, in 1985, the practice completed the 447-unit Dairy Farm Condominium for the Kuok Brothers. Open balconies and wide overhanging roofs, a transformation of traditional climatic responses into contemporary technology, give the residential units a tropical aesthetic lacking in most recent condominiums. Ironically, the Building Control Department (BCD) regulations in Singapore have regressed in some respects, for they inadvertantly do not actively encourage ecologically-responsive housing. Balconies and roof overhangs in housing projects which exceed 1.4 metres are now included in Gross Floor Area (GFA) calculations and consequently, developers often enclose and air-condition them. Because of this, such buildings are frequently less environmentally-sensitive than many built 20 years ago. The Dairy Farm Condominium is a reminder of a solution which combines the benefits of living in harmony with nature whilst at the same time providing increased density. The Selegie Complex completed in the same year indicated an early, albeit tentative, attempt at developing a design language of line, edge and shade in an urban context.

In 1985, Tay attended an important International Conference held in Kuala Lumpur organised by the Malaysian Institute of Architects (PAM) and the Aga Khan Program for Islamic Studies at Harvard University and MIT. At that conference, Julian Beinhart of MIT, summarising the mood of the seminar, proposed a research programme on the form of cities in the tropics, the Southeast Asian City or the 'low-energy' city.
The West, he pointed out, has a tradition of designing city forms especially in the late nineteenth and early twentieth century. Le Corbusier's Une Ville Contemporaine and Ebenezer Howard's Garden City are two examples and they have been used selectively all over the world. Even today, they influence city design in all countries including those in the tropics.

The Tropical City: A sketch by Tay Kheng Soon (1989)

A house on Mt. Rosie photographed by Tay Kheng Soon in 1963 and now demolished, was a source for the language of Line, Edge, Mesh and shade.

The entire first storey is given over to the public as a sheltered plaza. It is conceived as a prototype of large, covered and linked verandah spaces in the city. It is a shaded interactive outdoor space, an oasis, which poses the question why do so few modern office towers contribute to the public realm in this manner. Why is the conviviality of traditional streets missing from the Central Business District? Such critical questions are invariably evident in Akitek Tenggara's buildings.

Later in 1986, the practice completed Serangoon Gardens Country Club, which marked a further step in the development of a modern design language for the tropics. On this occasion, the building type was a low-rise private club with a large covered outdoor space. Central to this project is a total reappraisal of what makes living in the tropics different; what makes it unique. Tay sees this building as one of the benchmarks in the development of an urban tropical design language and morphology. This bold architectural approach explored new frontiers in technology and finds new expressions of traditional and cultural patterns at a time when many new building designs were being transported wholesale to Singapore by foreign design consultants.

Chancery Lodge Townhouses were also completed in 1986. This small suburban residential development has a number of well worked-out architectural elements which give the development its tropical character. Jack-roofs and monsoon windows are used along with a system of open timber trellis beams which provide shade and visually integrate the whole development.

An indication of Tay's scepticism of the buildings emerging in the heady years of a newly independent nation was conveyed in the title of a paper given at an ARCASIA conference in Beijing in 1987, 'A World Class City deserves a World Class Architecture'. The implication was that Singapore was not getting the quality of buildings it deserves. The influence of unsympathetic foreign architects came in for severe criticism in the paper and Tay raises questions of the appropriateness of imported forms and architectural languages. "A world class architecture," he pointed out, "will not come about by recycling other people's ideas. Foreign expertise has not broken any new ground. Foreign designs brought to Singapore have not surfaced any new design issues in themes intrinsic to Singapore. The designs are conventional and conservative. They serve only as corporate status symbols."

In 1987, the practice completed the Chee Tong Temple in Hougang. It is another important building in the development of a design language for the tropics albeit addressing issues of tradition. On this occasion, it was a convincing transformation into modern architecture of a traditional religious building type. The architects believe that the building, "seems to have touched some deep common chord of consciousness and that it confirms that architecture can be made to respond to deeper imperatives than those obvious and literal stylistic motifs used as convenient signs and symbols of identity in a pastiche manner."

In 1988, the practice won a competition for the redevelopment of Kandang Kerbau Hospital in Singapore. The project had a chequered history. The site was changed after the competition was won and the brief, too, went through various amendments. Then, in a surprising turn of events, the competition jury's verdict was overturned and the com-mission was taken over by the Public Works Department (PWD). Tay Kheng Soon appealed to Mr S Dhanabalan, the then Minister for National Development, who intervened, and a compromise was worked out whereby the design work was done by Akitek Tenggara assisted by hospital consultants McConnell Smith and Johnson of Australia, with the Public Works Department (PWD) as Principal Consultants carrying out the contract administration. The hospital was completed in March 1997 and despite the separation of responsiblities, the clarity of the design by Akitek Tenggara has been realised. The project takes the notion of Line, Edge and Shade to a new level of sophistication.

of the design by Akitek Tenggara has been realised. The project takes the notion of Line, Edge and Shade to a new level of sophistication. In October 1988, the opportunity arose for Tay Kheng Soon to develop his ideas on 'The Tropical City.' Ho Pak Toe, one of his erstwhile collaborators in SPUR, was by then Director of the School of Architecture at the National University of Singapore. Ho Pak Toe invited Tay to conduct a workshop with senior students on the theme of the Intelligent Tropical City (Tay 1988). The programme would explore ideas set out in a working paper by Tay which sought to advance the paradigm of the Intelligent Tropical City.

A programme was devised to model the concept of The Tropical City. Singapore's population will expand by 1.3 million people in the next 40 years. What kind of city would emerge if 500,000 people were accommodated on the reclaimed land adjacent to Marina Bay? This was the proposition explored, a proposition which would maintain those parts of the island, as yet undeveloped, for recreation, nature reserves and forest reserve. These reserves are presently threatened with reduction into mere tokens.

The mathematical model and the fixed volume model initially looked daunting but the gross plot ratios arrived at were acceptable at 12.5. The final spatial model of the concept had a delightful quality of urban spaces and immense vitality even though the densities were high.

In exploring the conceptual framework provided by Tay, the student workshop developed specific guidelines for:
o Landscaping
o Support structures
o Tropical design
o Community in high-rise dwellings
o Tools for conviviality
o Transport technology
o Building technology
o Information technology

The workshop tested The Tropical City proposition and assisted in the formulation of the agenda for future research. The results were helpful to Tay in modelling many aspects of the Tropical City which was subsequently published as a book, Mega-Cities in the Tropics by the Institute of Southeast Asian Studies (ISEAS) (Tay 1989). Tay received support in his research from the late Professor Kernial Singh Sandhu at ISEAS where Tay was appointed Research Associate from 1988 to 1989 and at the Aga Khan Programme at MIT where he was appointed as a Visiting Scholar in 1986 and in 1989. Yet another project won in competition, the Nanyang Technological University Hall of Residence No.V was completed in 1989. The hall is a modern reinterpretation of traditional ways of responding to the tropical climate. Light wells, covered walk-ways, open-to-sky spaces and deep window reveals all work well within the compact plan. Most importantly, post-occupancy evaluation has shown that the design approach
in Hall of Residence No.V is 16% more energy efficient than the average of newly built halls on the NTU campus.

In 1990, Tay achieved an apparent breakthrough. The publication of 'Mega-Cities in the Tropics' and the positive assessment given of the buildings produced by the practice, notably in the book Innovative Architecture of Singapore (Powell 1989), led to an invitation from the then Minister of National Development, Mr S Dhanabalan, to prepare a Development Guide Plan (DGP) for a 76 hectare site on the fringe of the central area of Singapore known as Kampong Bugis. It was an inspired move by the Minister; in effect he challenged Tay and the Singapore Institute of Architects to produce a viable plan to integrate the ideas on the Tropical Asian City that Tay had been vociferously propounding for almost a decade. Tay was appointed by the SIA to lead a team on the project. His frequent criticism of the government agencies' approach was now put to the test. Could he produce a radical yet workable alternative? The time was past for abstract theories, the alternative would have to pass detailed scrutiny and empirical analysis by those who for years had borne the brunt of Tay's criticism.

Tay assembled a core team of professionals. The Revised Concept Plan for Singapore was still being prepared (it was not published until 1991), so Tay seized the opportunity to question the whole urbanisation strategy for the island. The team eventually produced a radical new approach to planning the city in the tropics, in effect answering the chal-lenge thrown down by Beinhart at the Kuala Lumpur conference in 1984. Given the Tay Kheng Soon model and an alternative plan by the URA which effectively continued the successful policies of the past, the government accepted the URA version.

Perhaps it was inevitable, for it would have been an admission of the limitations of its own metho-dology to have done otherwise. It was not that the URA produced a bad plan, simply that it lacked a vision of the Tropical City in the 21st century. Pragmatic, buildable and based on a proven formula, it did not engage in any rethinking of previous norms. It did not address the question of how the island could become more hospitable to nature or how an island-city-state could be more sustainable.

Tay Kheng Soon is philosophical about the outcome. "There is a certain inertia to planning policy and it is difficult to deflect it from its customary trajectory. At the same time, there is a tacit acceptance that we were correct: you see there has been a gradual increase in Plot Ratios in subsequent plans. In the Newton DGP, for example, a Plot Ratio of 4.5 is now being proposed which is precisely what we had advocated at Kampong Bugis. Light Rail Transit (LRT) is now being widely seen as an addition to buses and MRT. We had proposed this in the Kampong Bugis DGP and likewise, the idea of service tunnels beneath highways. It is all a matter of time before the ideas win acceptance."

Chung puts it another way, "The state is the largest landowner, but it restrains new possibilities by assuming past models. Certain attitudes are entrenched. It is difficult to pinpoint but in some respects, we have not moved very far and when new ideas come up, such as those proposed in the Kampong Bugis DGP, it is difficult for them to gain acceptance. The idea of vertical planting, for example, needs political will if it is to succeed: we are willing to do the research to verify ideas but it is dependent on
enlightened and imaginative patronage."

A D e s i g n L a n g u a g e f o r T r o p i c a l A s i a

In 1990, Tay wrote a seminal essay on The Architectural Aesthetics of Tropicality; an essay which summarised the progress to date in developing a design language for Tropical Asia. In the words of Patrick Chia, "It clarifies our position. It brings together a body of ideas, not a style of architecture but a way of thinking. It is both a look back-wards to assess what we have learnt and a look forwards to see what we can do based on this knowledge."

It amounts to a new theory of architecture. It is the outcome of a struggle in every sense of the word against deeply entrenched bias towards western models, parochial thinking in the profession and the centralisation of design opinion in Singapore which has tended to dampen new initiatives. "Perhaps by publishing these ideas at this juncture," says Chia, "it will encourage others to pause and to see if there is another route that we in Asia can take. If we do no more than raise questions, that will be enough." It is difficult to develop theory in the world of practice which is dominated by market forces.

How many clients are prepared to take the risk of experimenting with new ideas? Akitek Tenggara has been unusually lucky in having a few remarkable clients but it is also notable just how much of their work has had to be been won in competitions. "There is undoubtedly a struggle to develop an appropriate design language for the tropics," says Chia, "in fact there are two struggles. Firstly, there is the struggle against the establishment against entrenched ideas, and this is well-illustrated by the struggle that Tay Kheng Soon had in the early years of the practice. But there is another struggle which has an internal dimension, everyone of us comes to this. It is a private struggle, within oneself, what I call the unfinished business. In this time of rapid economic expansion, how do we stand with the rest of the world? How then should we design? Should it be in the manner of I M Pei or Kevin Roche or Norman Foster? What is the authentic response? If you are a conscientious architect in the Third World, you want to be involved in this. In the 1960's and 1970's there was ferment, there could not be consensus. But now is a different time with different ideals, different visions."

Later in 1990, the practice produced the Victoria Street Concept Plan, an urban study which built upon the Kampong Bugis DGP. The new study recommended the repopulation of the central area of Singapore, reversing the massive depopulation that resulted from a housing policy encouraged by the British New Town model. Akitek Tenggara recommended the provision of dense urban morphologies. In the Victoria Street area alone, residential accommodation for some 18,000 people was proposed.

In 1989, Akitek Tenggara won a competition for the design of an Institute of Technical Education (ITE) at Bishan. The design language of line, edge and shade reached a new level of refinement. "The traditional Malay-Village-response to the tropical climate is marvellous," explains Patrick Chia, "they had breathing walls, monsoon windows, raised floors and the air just went through to provide a perfectly balanced climatic response."

"You have to resurrect the idea of cross-ventilation. You have to use large roof eaves, because you want shadows and protection from driving rain and you want to use the Venturi effect to accelerate the air flow and create comfort." On the question of a design language for the tropics, Chia says, "With today's technology and the use of energy, you can lower the temperature to create comfort conditions, but in the ITE, comfort is achieved by allowing air to move, thereby controlling humidity and tempe-rature. If you can make all these things work simultaneously, you can achieve comfort at much less cost than by guzzling energy."

Chia is equally adamant about the need to develop a design language for the tropics. "You can consume indefinitely but you have to express yourself and make a statement about who you are. We crossed the threshold of basic needs about 15 years ago when we solved most of our infrastructure problems, so it's now time to ask who we are in the world community."

Chia goes on, "Here, the light is strong and at times produces very precise shadows so what you want to create is an architecture of lines and shadows as opposed to a temperate climate where

you use planes and volumes to make your statement. In the tropics, you should design with lines, shadows and horizontality. This is because the high vapour content in the air tends to diffuse the light. Volumetric forms don't stand out anywhere nearly as well as lines and edges. Those volumetric forms you see in Manhattan do not sit well here. Basically, in the tropics, you just need an 'umbrella' for a roof. You do not need to fight the elements. This is where the informality of Asian lifestyles comes out."

The Institute of Technical Education was completed in 1993. "At ITE Bishan, we wanted to encapsulate a microcosm of the city in a tropical climate," concludes Chia, "A very sad thing is happening in architecture in that there is a lot of glossing over of the artifact. The historical motif is creeping back. These are not authentic expressions of our time. Ours is a neo-industrial age. Here we are standing at the gateway of the 21st century yet we see people going back and copying history!". Strong words from Chia and an indictment of the classicist post-modern façadism that passes for architecture in many countries in Southeast Asia. "One of the greatest problems of being an architect,' says Chia, "is knowing how to restrain oneself, knowing when enough is enough."

The ITE was a conceptual breakthrough and in subsequent competition entries for other ITE buildings at Bedok, Balestier and Bukit Batok the practice attempted to advance the ideas further but they were unsuccessful in all three competitions. "The emotional damage is serious when this happens," says Tay. "In competitions, you have to risk all and thus there is an enormous commitment in time, energy and emotion."

Chia agrees,"The tragedy of the competition process is that there is a lack of continuity in developing ideas. Nevertheless, it is immensely challenging. You have to be more rigorous and demanding of yourself. You have to demonstrate superiority in a few drawings. Many subtleties are not visible; when you want to do something new or different you have to ask yourself why. This leads to the opening of minds, to creating conditions of change. It is immensely stimulating."

An indication of the increasing international recognition of the work of Akitek Tenggara came in 1993 when Tay Kheng Soon was invited to be a judge, along with Sir Norman Foster, Sir Richard Rogers and Philip Cox of the prestigious Quaternario Awards.

practice's earlier explorations and produced a stunningly beautiful contemporary dwelling.

The passion with which Tay Kheng Soon promotes the cause of an architectural language for Tropical Asia inevitably creates controversy; for it spills over into the spheres of culture and of politics. In 1994 he wrote a critical article in the Straits Times (ST July 30th) on the subject of the proposed Singapore National Arts Centre designed by Michael Wilford Associates in association with the Singapore practice of DP Architects Pte Ltd. "The project," says Tay," focusses on the dilemma of being Asian and Modern at the same time. On the cultural symbolic level, the acceptance of the dominance of the western-type performance hall structures is symbolic of an implicit acceptance of the dominance of western arts in the consciousness. That the huge structures are allowed to overshadow actually and symbolically the diminutive Asian arts performance spaces is a demonstration of insufficient consciousness of this as a cultural issue in design." The criticism of this potential national icon created a political furore although many agree with Tay's comments. Dramatist Kuo Pao Kun put it succinctly when he said, "this arts centre should not be the last of the great western arts centres, but the first of a series of Asian ones."

Tay went on to suggest that a certain mundane-ness (sic) has crept into the design, a mundane-ness that can only be corrected by providing more scope for the celebration of the outdoors in the design of the Asian arts section of the complex. The timidity with which the proposals have subsequently been revealed to the public suggests a lack of conviction on the part of the designers regarding these cultural issues.

In 1995, Tay took on a major role in organising the 8th Congress of the Architects Regional Council of Asia (ARCASIA) and presented a paper on urbanisation patterns in the region. The theme of the congress was 'Asian Cities in Asia's Century'. The claim that the 21st Century could see the economic resurgence of Asia is well founded. A period of impressive growth and physical transformation is already evident but the impact of this on the Asian Cities is giving cause for concern. It is far from the 'brave new world' that many have anticipated. Asian Cities are becoming extremely congested and highly polluted, not to say downright ugly, and it was these looming problems which focussed the minds of the delegates.

What should be the form and shape of Asia's Cities in the next century? Tay Kheng Soon's paper discussed essential spatial operations to address the ecology versus urbanisation conundrum. If the region is to become increasingly urbanised without undermining the balance with the natural environment, then spatial morphologies and built forms must be found which permit the development of high-density, compact settlements and which simultaneously do not have a negative impact on the environment. The disciplines of spatial morphology and built-form typology enable other disciplines to be harnessed in order to model space, energy, administration, finance and eco-environmental propositions at regional and local scales.

Tay went on to define what is meant by the term Spatial Operations. It is the relationship between height, block depth, site coverage and plot ratio. These constitute the independent variables which determine form. If one has a height restriction of say 3 storeys and the plot ratio is determined to be 2:1, a quick calculation reveals that the site coverage will be 2 divided by 3, i.e. 66%. All variations can be determined when the other three are fixed. Past knowledge of buildings shows that there are few successful designs which fulfill these parameters as the block depth will be considerable and the design will have to rely on internal courtyards and light wells. He cited an example in Fukuoka, Japan by Rem Koolhaas which extended the frontiers of high-density low-rise solutions for housing and which solved the problem of great block-depth elegantly. Without mastery of morphology, designers are trapped in premature spatial and form rejection and are caught in mindless repetition of past models.

Dealing next with the context, Tay advanced the proposition that the economic and political complementarity of Singapore, Johore and Riau province in Sumatra (SIJORI) is greater than the competition between them. The advanced technology, global business network and infrastructure of Singapore, added to the vast material, mineral and agricultural resources of Riau and Johore together with their combined population represent a development potential of regional and global significance.

Anticipating the scale of the development, it was assumed that greater parity of income is obviously desirable between Riau, Johore and Singapore than at present. A levelling upwards would generate a vast increase in economic activity and propel an in-migration of population upwards of 20 million. In spatial terms, one might expect a three-fold increase in urban floor space and infrastructure. This, as Tay pointed out, is both the consequence and the catalyst of economic development. He posed the following questions:

o What will this increase do to the environmental conditions in existing cities and towns?
o How many new settlements need to be constructed? In what manner? Where?
o What will this massive development, with its attendant pollution and demands on resources do to the natural environment?

The spatial strategy for SIJORI is based on catalyzing a new growth cycle by pooling the resources, capital, skills and infrastructures of the three territories. The construction of physical linkages in the form of a system of trans-national tunnels and bridges is the key catalyst. These would link Johore to Singapore to Karimun Island, then west to Sumatra and east to Batam. These linkages would in effect create one economic zone augmented by the existing telecommunications, shipping and air traffic links. The urbanisation of the enlarged economic region is conceptualised as nodal clusters along the trunk linkages with large natural areas in-between. It is postulated that this string of human interventions in the landscape will not only be cost-effective but also environmentally more friendly.

The spatialisation pattern is then linked to the demand and supply of labour, to sustainable use of resources and to nature conservation. The thrust of Tay Kheng Soon's paper was devoted to a spatialisation strategy for SIJORI and the exploration of the relationship between built form, CO2 generation and nature conservation. The paper offered a critique of planning models currently used and the disparate approaches of the different land-development disciplines. He explained how Morphological Research would give insights to designers in terms of urban layout and built-form in a stylistically unprejudiced manner. This view is substantiated by reference to Lionel March's investigations with Leslie Martin and others at the Centre of Built Form Studies at Cambridge, published in 1972 in the book 'Urban Space and Structure". This part of Tay's paper concluded with a proposed model for "A Compact, Low CO2-Generating City in the Tropics." The model was elaborated in some detail, including its relationship with its rural hinterland, the ecological impact, carbon dioxide emission, tropical forest conservation and food production as one system.

Rem Koolhaas, a guest speaker at the Congress, remarked that there is at present a bankruptcy of planning solutions for Asian Cities. Planning in the conventional, con-servative sense cannot deal with the modern city which in many cases is propelled by forces which are out of control. Planning has died without a whisper, surrendering to the homogenising forces of globalisation, capitalism and consumerism. In the face of this scenario, there is in the west a retreat to sentimentality for the past, nostalgia for tradition. Professor Tunney Lee, responding to Tay's paper, remarked that Asia is a high density context and that, "We should rid ourselves of the sentimentality of the West." Tay Kheng Soon's SIJORI paper represented a substantial shift from the received wisdom of western planning models. It rejected low-density planning solutions in the face of rapid urbanisation.

In 1995 and 1996 Akitek Tenggara completed work on three school projects: Elias Park Primary School, Clementi Town Secondary School and Beatty Secondary School. The Elias Park Primary School, in particular, raises questions on the nature of education and school design in Singapore at the end of the millennia. It challenges the notion that a school ought to have an imposing or monumental entrance. The design intention is to diminish the scale of the building so that it is perceived as a place for children and to make it an environment of constant discovery. It is a continuation of the process of developing an architectural language for the tropics and emphasises the interaction of children with the natural environment.

In early 1996, the practice underwent another self-renewal exercise. CP Lee, an AA graduate and a very strong maker of building forms, who had been a partner since 1987, left to pursue his own direction and Winston Yeh, a Harvard-educated architect and urban designer, amalgamated his Hong Kong practice with Akitek Tenggara. Formerly, the two practices had been associated through Pacific Asia International Ltd. Yeh was a member of the design team that formulated the Kampong Bugis DGP and it presents the enticing possibility that given Yeh's decade of experience of planning and urban design in China, the intelligent city, with accompanying dense morphologies, could yet be built, though in a different climatic context.

religions do provide me with an attitude to design. Love and kindness are things shared by all religions; love for individuals, for groups, for the environment; isn't this the ultimate criteria? Translating 'love and kindness' into specific architectural and planning terms is not easy. It is neccessary to resolve many difficult conflicts. I like the notion that William Morris had, that the end product should be a beautiful object as well as a utilitarian object. The space and time in producing these objects should also be pleasurable."

In November 1996, Tay delivered a paper in Kumamoto, Japan, entitled Architecture of the Future: the Challenge to Asia and the West. The title is significant in that it acknowledges the interconnectedness of the global economy and the global ecology. The paper enlarges upon The Tropical City concept to include the supporting region in the form of considerations for the production of food supply, water collection and CO2 absorption.

In early 1997, two major projects were completed which reveal the practice's progress in developing a design language for the tropics and in examining new morphological patterns for high-density housing. These are Kandang Kerbau Hospital and Choa Chu Kang Public Housing Precinct; both projects won in competitions. In 1982, Akitek Tenggara had made proposals to the HDB for Design-and-Build Housing but at the time it was judged to be inappropriate. The housing scheme at Choa Chu Kang critically questions many accepted norms in public housing in Singapore. Car parking, for example, is moved to the perimeter of the housing project and the block depth is increased. This opens up new permutations in the spacing of blocks.

These are both ideas that Tay Kheng Soon has advocated for many years, most recently in Thoughts on Mass Housing (Tay 1991). Kandang Kerbau Hospital, completed in March 1997, brings the development of the design language of line, edge and shade to a new level of sophistication. Tay has some minor criticisms of the way the project has materialised. It was the practice's intention that the western site boundary would merge with the adjoining lily pond in Kampong Java Park and that there would be a blurring of edges. But the boundary eventually set has inhibited the full potential here.

Tay Kheng Soon continues to cultivate controversy and the Singapore administrative establishment treats him warily. This is something he has grown to live with and perhaps it is the fate of the radical intellectual in any society. However, his international stature as an architect and educator was recognised by the invitation in 1996 to become Adjunct Professor at the prestigious RMIT School of Architecture, Australia. Also in 1996, he was an invited speaker at the UIA Congress in Barcelona and is to be an exhibitor alongside Peter Eisenman, Toyo Ito, Jean Nouvel and Rem Koolhaas at the Pompidou Centre in Paris, in an exhibition entitled Enquete sur l'architecture proche (Approaching Architecture: an Enquiry), scheduled to take place in 1997.

The search for a design language for the tropics and the process of (un)learning that it implies has a remarkable symmetry with the process of decolonisation. The practice is now, in Chia's words,"... in a period of transition. Increasingly, work is done outside Singapore. The arrival of Winston Yeh in 1996 will possibly accelerate this process. Our abilities are not just confined to this context. Our approach to design in a comprehensive manner is applicable in different contexts, the context of China, where we are currently doing masterplanning projects, the context of Fiji, where the practice is currently working on the World Trade Centre in Suva and the context of the Philippines where we are preparing proposals for low-income housing."

Chia expands on this,"The cities of Asia are also in transition. Many are going through periods of self-doubt as they are becoming more corporatised, losing their identity. There is a 'facelessness' about things. This situation is serious, this transformation of cities according to the logic of capitalism. I am not critical of foreign architects working in Asia but I am critical of those irresponsible foreign architects who are harnessed by these faceless corporations and who are not sympathetic to these issues. What we need are enlightened patrons who are alert to the need to create cities which are much richer and serve other agendas, not just the narrow agenda of capitalism, they are not mutually exclusive."

"As a practice, we perhaps do not take enough care to 'present' ourselves, to dress correctly, to appear in the 'right' places, but the problems that are affecting Asian Cities are much more pressing and so much more challenging than narrow professional politics."

Central to the work of Akitek Tenggara for more than two decades has been a responsiveness to the natural world and a concern for sustainable or 'green' architecture long before it became fashionable to include this in one's agenda. This does not infer a nostalgic return to past forms but a commitment to a design language for the tropics using a modern vocabulary. This was evident in the early days of the practice with the low-income social housing at Cheras in 1976, and in the most recent work such as the
