Ken Yeang


Ken Yeang is a Malaysian architect, ecologist, planner and author, noted for his work in ecological architecture and eco-masterplanning. Since the early 1970s he has developed an approach to design grounded in ecology and environmental sustainability. In 2008, The Guardian included him in its list of "50 people who could save the planet". Yeang’s architectural practice, Hamzah & Yeang, is based in Kuala Lumpur, with associated offices in London as Llewelyn Davies Ken Yeang Ltd. and in Beijing as the North Hamzah Yeang Architectural and Engineering Company.

Biography

Formative Years

Yeang was born in Penang, Malaysia, he attended Penang Free School and entered Cheltenham College.
He qualified in architecture from the AA School of Architecture where he did freelance illustrations and graphic work for the AD, AAQ magazines and for the AA. His dissertation at Cambridge University, "A Theoretical Framework for Incorporating Ecological Considerations in the Design and Planning of the Built Environment" earned him a PhD, published as ‘Designing With Nature’ and as 'Proyectar Con La Naturaleza’. Academically, he holds the Distinguished Plym Professor chair. His honorary degrees include D.Litt., PhD , D. Arch , D.Sc .

Professional career

He is registered as an architect with ARB , RIBA , PAM, and Singapore Institute of Architects. He is a Fellow of the SIA, Fellow of the AIA, Fellow of the Royal Incorporation of Architects in Scotland, and Fellow Wolfson College, Cambridge University.
Yeang interned at S.T.S. Leong, worked at Louis de Soisson Partnership, Akitek Bersekutu which became T. R. Hamzah & Yeang Sdn. Bhd.. Yeang also served as Design Director and Chairman for Llewelyn Davies Ken Yeang until it was dissolved in 2012.
Yeang has completed over 12 bioclimatic eco high-rise buildings, several thousand dwellings, over two million sq. ft. interior design space, numerous eco-master plans and eco-city designs.
Yeang lectures extensively at conferences and schools of architecture. He currently holds the Distinguished Plym Professorship chair. He has been Professor of Practice, Provost’s Distinguished Visiting Scholar, Visiting Eminent Scholar, Advisory Professor, Honorary Professor, misc. Adjunct Professorships,
His key built work include the Roof-Roof House, Menara Mesiniaga , National Library Singapore, Solaris, Spire Edge Tower, DiGi Data Centre, Great Ormond Street Children's Hospital Extension, the Genome Research Building, Suasana Putrajaya.

Work on Ecological Design

Yeang’s research has focused on ecological architecture and masterplanning, particularly on the integration of built structures with natural systems. His approach emphasizes bioclimatic design, climate-responsive, passive, and low-energy strategies, as part of a broader ecological framework. He has also explored how biodiversity can be incorporated into buildings through habitat creation and vegetation systems.
One of his early experimental projects was his own residence, the Roof-Roof House in Selangor, Malaysia, which included features such as a louvred roof canopy for solar shading, wind-directing walls, and a pool designed to assist with evaporative cooling. Elements from this house informed his later large-scale work.
Yeang extended his principles to high-rise design, developing the concept of the “bioclimatic skyscraper.” The Mesiniaga Tower, an office building for IBM in Subang Jaya, Malaysia, incorporated strategies such as a shaded façade, recessed terraces, a rooftop pool, and a vegetated exterior. The building received the Aga Khan Award for Architecture in 1995 and other regional architectural awards.
In Singapore, Yeang’s Solaris building featured a continuous vegetated ramp forming a “vertical linear park,” integrating green spaces into the circulation of the tower. His later projects, such as Suasana Putrajaya and the National Library of Singapore, further developed ideas of “vertical green urbanism,” including sky gardens, naturally ventilated atria, and green infrastructure networks. He has also applied these principles internationally in projects such as the SOMA Masterplan in Bangalore, India, and the Spire Edge Tower in Gurgaon, India.
Yeang’s theoretical work includes proposals for “eco-mimicry,” or designing buildings and cities as constructed ecosystems that reflect ecological processes and structures rather than imitating their appearance. His doctoral research at the University of Cambridge in the 1970s laid out a systemic model for eco-design, which continues to inform his later architectural and planning work.

Key Projects

Yeang has completed over 200 built projects since 1975. His benchmark buildings, projects and their innovations include:
  • The EDITT Tower – Waterloo Road, Singapore – a 2ndn prize winner, EDITT competition.
The project has been published in over 30 international publications for its hirsute extensively-vegetated ramp façade and aesthetic.
  • The Roof Roof House – Selangor, Malaysia – an experimental climate-responsive house that rethought bioclimatic passive-mode low-energy building design.
  • Menara Mesiniaga Tower – Selangor, Malaysia – a climate-responsive tower that exemplifies Yeang’s key principles for 'bioclimatic skyscraper' design, and received the Aga Khan Award for Architecture, the RAIA International Award, the Malaysian institute of Architects Design Award.
  • Kowloon Waterfront Masterplan – Hong Kong – a green masterplan where Yeang developed the green eco infrastructure concept and the novel use of 'eco cells'.
  • National Library – Singapore – a green library tower with large landscaped sky courts that received the BCA Green Mark Platinum Award 2005, and the Singapore Institute of Architects Award.
  • SOMA Masterplan – Bangalore, India – a signature eco masterplan that espouses his innovative idea for eco city masterplanning as the integration of four eco infrastructures, with the use of eco bridges and eco undercrofts to enable an ecological nexus across the terrain.
  • DiGi Technical Office – Shah Alam, Malaysia – advances the idea of a 'living' eco wall as a nexus of greenery linking all the facades. It received the Malaysian Institute of Architects Design Award and Green Building Index Gold rating.
  • Solaris Tower – 1-north, Singapore - with a 1.5 km long 'Vertical Linear Park' vegetated ramp that wraps itself around the tower's façade, a diagonal light-shaft, automated glass-louvers roof over the atrium, rain-check walls at the ground floor, which received the Singapore Institute of Architects Award, the Malaysian institute of Architects Gold Award 2011, the WACA Gold Medal 2011 and BCA Green Mark Platinum rating.
  • Spire Edge Tower –, under construction with anticipated completion 2013, a signature tower that espouses the idea of a vertical green eco infrastructure, LEED Platinum rating.
  • Ganendra Art House – Petaling Jaya, Malaysia – Art Gallery with accommodation for live-in artist has an experimental 'down-draft' ventilating flue for enhancing comfort cooling, received the Malaysian Institute of Architects Design Award 2010, Green Building Index certification rating.
  • The Great Ormond Street Children's Hospital Extension Phase 1 – London, UK, BREEAM 'excellent rating'
  • GyeongGi Development, Seoul, Korea – habitat creation that exemplifies the use of a Biodiversity Matrix that makes the development into a total 'living system'..
