Tan Kok Hiang

Principal Director
Forum Architects Pte Ltd

There is good reason Tan Kok Hiang describes his own architectural style as “thoughtful”. Take one of his favourite projects, the S$7.8m Assyafaah Mosque in Singapore. An architectural statement that has received multiple awards both locally and internationally, it neatly epitomises Kok Hiang’s approach to architecture: understanding the raison d’être of a building and creating a design that conveys this in context.

Dispensing with traditional domes and arches, the contemporary mosque looks different from what one would normally expect of such a building.

“Most mosques in Singapore are very Middle-Eastern modelled, so you’ll see arches and domes. And I used to think that they had nothing to do with Singapore”, he explains. Instead, Kok Hiang designed a thoroughly contemporary structure incorporating the arabesque, the design element predominant in Islamic buildings. This is defined as two or more geometric patterns coming together to form a third pattern, says Kok Hiang, who completed a thesis on Islamic architecture in university.

“These patterns were developed by scholars, maybe a thousand years ago, because they wanted an art form to represent the Qur’an. The Qur’an cannot be represented in figurative terms. You have to use abstract terms”.

About the Assyafaah Mosque in Admiralty Lane, Kok Hiang adds: “The happiest thing for me about this building is that it looks nothing like a Middle Eastern mosque. It is contemporary and it belongs more to Singapore. Today, many visit the mosque, including non-Muslims”. To Kok Hiang, the real triumph behind a well thought-through and executed project is for the architect and the client “to be able to think about the different aspects of a building, and its impact on the community, today as well as in the future”.

Another project he is proud of is the Singapore Chancery in Manila, the Philippines. He says: “It’s a functional building that has to exude a sense of what it means to be a Singaporean in a foreign country”. So Kok Hiang incorporated the landscaping to reflect Singapore’s positioning as a garden city. In addition, as Singaporeans are known to be precise, punctual and efficient, he designed the building, in spatial flow and physical form, to convey all these characteristics.

Kok Hiang also takes pride in the “rainbow wall” at the Singapore Science Centre that stretches past the entrance of the Centre to give the complex a new front, and orientate visitors to the main entrance.

Kok Hiang, 54, is Managing Director of his own firm Forum Architects Pte Ltd, which he established with his wife and fellow architect Ho Sweet Woon in 1994. Holder of a Bachelor of Arts degree (Architectural Studies, 1984) and a Bachelor of Architecture Honours Degree (1987) from the National University of Singapore, he has held numerous exhibitions and participated in various conferences locally and internationally and garnered more than 30 awards, including the Chicago Athenaeum International Architecture Award in 2008 and 2010, the URA Architectural Heritage Awards in 2007, and two nominations and an honourable mention in the President’s Design Award. He is also involved in architectural education and sits on several professional committees.

Early in his career, Kok Hiang had trained with William Lim and Tay Kheng Soon. He learned about building in context and having a deep concern for the environment from the two architecture veterans. From the latter, he also learned that an architect should be a partner to a client. “Not necessarily equal, but a partner. Then we have a shared objective: achieving something together as partners. This is a very important stance”, says Kok Hiang, recalling the advice.

When collaborating with a client who is a visionary, Kok Hiang is the partner who takes on the role of a facilitator. “If the client is pursuing his vision, I’m not going to force my own on him”. While not every client is a visionary, sometimes he or she may turn into one with a bit of help, according to Kok Hiang. He names the Japanese martial arts form, aikido, which he has been practising for the past 25 years, as having indirectly helped him in this regard. Aikido’s basic philosophy is harmony, Kok Hiang explains. In a conflict, aikido advises practitioners “to move in and confront the conflict and take charge of the situation from the weakest point”. By adapting the philosophy to his work, he can sometimes help his clients become visionaries.

Reviewing the evolution of Singapore’s design scene, Kok Hiang thinks the Urban Redevelopment Authority’s inaugural “20 under 45: A selection of works by under 45 Singapore-registered architects” in 2004, and subsequent instalments to have done much in creating design awareness in Singapore. When the exhibition moved to Venice as part of the La Biennale di Venezia, Kok Hiang feels a turning point was reached where Singapore’s talent in the field was given a place on a prominent world stage. For him, the President’s Design Award is a continuation of paying this homage to design.

Now that he has received the most prestigious of Singapore’s design awards, Kok Hiang says: “I want to continue looking for openings and opportunities. Architecture is about so much more than just space. It’s also about influencing people’s attitudes and lives, and always in relation to harmonious living”.

Insights from the Recipient

What does it mean to practise as a designer in Singapore?

I used to begrudge the conservativeness of architecture in Singapore. Then I look at some other countries that have been ahead of the curve. Maybe they have gone overboard and consequently their architecture has sometimes become wasteful and supercilious. Singapore's pace, on the other hand, has been measured and always in consideration of careful use of resources and technology. There has been extensive emphasis on urban planning and less desire for icons

How has Singapore's design industry evolved over the past decade or, indeed, since you started practising?

To me, the architectural design industry started in 2004 when Singapore participated for the first time in the Architectural Biennale in Venice. Around that period, a series of initiatives by the Urban Redevelopment Authority and DesignSingapore Council, helped by flourishing design publications, created an incredible ethos of design appreciation and environmental consciousness. Suddenly, clients sought good design. It didn't matter that sometimes, nobody knew what that meant.

What is the responsibility of a designer to the community or society?

The architect's role is to be the guardian of the built environment. A house owner may not care too much about the visual or environmental impact of his house, but the architect must be concerned about this.

Nominator Citation


Tan Kok Hiang is a very thorough person. He is a passionate architect who has opinions about what goes on in the world and how he can positively influence it through his architecture.

I first met him over 15 years ago. When we started working together on projects, I noted Kok Hiang’s thorough and holistic approach to architecture, and how he considered the importance of apparently small things in the context of seemingly bigger ones. There was also his concept of “care” in the design of a space. It’s remarkable how the layman feels comfortable in a space he has taken a lot of care to design and construct, as opposed to another space of the same size which has received somewhat less affection in the course of its creation by others.

Kok Hiang made it his business to address beyond the emotive concepts of line, edge, shade and the spatial qualities of solids and voids. His architecture remains to this day an alchemy of appropriateness, structure, relevance and congruity to the brief, formed through a continuous dialogue with the specifics of the project, and driven by the higher purposes of context, the city, the country and beyond. Kok Hiang’s Assyafaah mosque project epitomises all these in a project for the community, which he researched until he came up with a building with the kind of relevance that invited applause and gratitude from all involved. He has applied the same rigorous approach to the design of all his other projects, more recently, at the Yale School campus in Singapore.

It is with utmost pride that I nominate Kok Hiang, an alumni of NUS who has practised at the highest levels of design and social consciousness in Singapore, for the prestigious award.
