Organized by Singapore Institute of Architects, the SIA Architectural Design Awards is the most prestigious award implemented by SIA to promote and encourage excellence in architectural design. The intention is to recognize the efforts of SIA members in their pursuit of architectural excellence and innovative solutions. It is also aimed at heightening the appreciation and patronage of good architectural design from both the architectural fraternity as well as the general public.

21 Jervois Hill was awarded Honorary Mentioned under the Residential Category for Individual Houses during the 10th SIA Architectural Design Awards 2010. This award serves as an encouragement to the quality of architecture that AR43 hopes to sustain and improve further in many more building projects to come.
