The SIA Architectural Design Awards – Singapore Institute of Architects’ pinnacle recognition – stands as a beacon for excellence in architectural design. Breaking new ground, the results of this prestigious accolade will be unveiled at the inaugural integrated Singapore Archifest 2024 (15th-17th May 2024).

These awards honour SIA Members for their exceptional contributions to architectural excellence and innovation, emphasizing their vital role in fostering meaningful conversations about architecture both within and beyond the discipline. A distinguished panel of jurors has been curated to meticulously evaluate this year’s projects.

For the first time, we are inviting our friends from the 4-Nations partnership to participate in the “Overseas Residential Projects” category. We are also re-introducing the “Small Houses” category to spotlight the creativity of our younger architects from small firms. This award cycle will truly be inclusive and exciting. SIA invites all eligible members to partake in the SIA Architectural Design Awards 2024, amplifying the appreciation and patronage of exemplary architectural design within the professional and public spheres.

Gallop Extension at Singapore Botanic Gardens by Kay Ngee Tan Architects
A once in a lifetime project where architecture, landscaping, heritage, and conservation come together as one.
