Sia Koh is a Singaporean architect and urban designer known for integrating tropical ecology, heritage conservation, and climate resilience into large-scale urban interventions. Her practice has spanned public-sector commissions, international competitions, and academic collaborations, linking projects in Southeast Asia, East Asia, and global design networks. Koh's work commonly interfaces with entities ranging from municipal authorities to conservation NGOs and international development banks.
Born in Singapore, Koh trained in architecture and urbanism at the Massachusetts Institute of Technology and completed postgraduate studies at the University of Cambridge. During her formative years she engaged with practitioners and institutions including the National University of Singapore's Department of Architecture, the Architectural Association School of Architecture, and studios affiliated with the Royal Institute of British Architects. Early mentors and influencers in her trajectory included figures associated with the World Heritage Committee, the International Federation of Landscape Architects, and design theorists linked to Princeton University and the École des Beaux-Arts. She undertook fellowships and research residencies that connected her with the Harvard Graduate School of Design, the Smithsonian Institution, and the Asia-Europe Foundation.
Koh founded a multidisciplinary studio that has collaborated with municipal agencies such as the Urban Redevelopment Authority (Singapore), regional bodies like the ASEAN Secretariat, and international organizations including the United Nations Development Programme and the World Bank. Her studio's commissions have ranged from waterfront masterplans to heritage precinct revitalizations executed in partnership with the National Heritage Board (Singapore), the Japan International Cooperation Agency, and the Asian Development Bank. Koh has also been a visiting professor and studio critic at institutions such as the Royal College of Art, the Tokyo Institute of Technology, and the University of Melbourne, and she has lectured at symposiums hosted by the Venice Biennale of Architecture, the Stockholm Resilience Centre, and the World Cities Summit.
Her professional affiliations include membership in the Singapore Institute of Architects, the International Union of Architects, and advisory roles for the International Council on Monuments and Sites. Koh's practice has operated across design, policy advisory, and research, assembling teams with experts from Aga Khan Trust for Culture projects, the National Parks Board (Singapore), and private engineering consultancies such as Arup and Atkins.
Koh led the masterplan for the Marina Bay Greenbelt, a resilience-led landscape initiative produced in collaboration with the U.S. Green Building Council, the Gardens by the Bay team, and consultants from Foster + Partners and Sasaki Associates. The project linked coastal defenses, mangrove restoration, and cultural programming in coordination with the Marina Bay Sands precinct and agencies including the Land Transport Authority.
Another notable commission was the Kampong Renewal Project, a conservation-led regeneration of a historic neighborhood undertaken with the National Heritage Board (Singapore), the Heritage Conservation Centre (Singapore), and community partners associated with the People's Action Party municipal outreach. This intervention integrated conservation standards informed by the UNESCO World Heritage Centre and technical input from the ICOMOS network.
Koh's Southeast Asia Waterfront Vision won awards in international competitions judged by panels containing judges from Zaha Hadid Architects, the Royal Institute of British Architects, and the International Federation of Landscape Architects. The vision brought together hydraulic engineering from Mott MacDonald, ecological science collaborators from the Institute of Tropical Biology and Conservation, and cultural programming advisors from the National Arts Council (Singapore).
Her published design research, in collaboration with scholars from the National University of Singapore and the Smithsonian Tropical Research Institute, addressed urban heat mitigation strategies referenced by municipal climate plans and cited in policy dialogues convened by the Global Covenant of Mayors for Climate & Energy.
Koh's personal networks include partnerships with colleagues educated at Columbia University and the ETH Zurich, and she has participated in exchange programs with the Singapore-ETH Centre. She has received honors including awards from the President's Design Award (Singapore), fellowships granted by the Asia Foundation, and research prizes from the Loeb Fellowship (Harvard). Koh has been profiled in publications produced by Dezeen, Architectural Review, and the New York Times's architecture desk, and her studio has been shortlisted by juries from the Pritzker Architecture Prize advisory circles and the Mies van der Rohe Award.
She serves on advisory panels for cultural institutions such as the Asian Civilisations Museum and the National Gallery Singapore and participates in philanthropic initiatives connected to the Temasek Trust and the Khee Foundation.
Koh's practice is cited in case studies and curricula at the Harvard Graduate School of Design, the University of Cambridge, and the National University of Singapore for demonstrating integrated approaches to tropical urbanism that bridge conservation and climate adaptation. Her collaborative methodology influenced municipal frameworks developed with the Urban Redevelopment Authority (Singapore) and informed design guidelines promoted by the International Federation of Landscape Architects.
Her protégés and collaborators have taken leadership positions at firms such as Atelier Jean Nouvel, WOHA Architects, and Buro Happold and within agencies including the Land Transport Authority and the National Heritage Board (Singapore), spreading her approaches across projects in Jakarta, Bangkok, Manila, Kuala Lumpur, and Ho Chi Minh City. Koh's body of work contributed to dialogues at the Venice Biennale of Architecture and policy fora of the United Nations Environment Programme, establishing models for resilient waterfront design adopted in regional strategies by the Asian Development Bank.
