I worked at Housing and Development Board in the late 80s and I was lucky to be given the opportunities to design a few buildings. Most of the HDB architects were either designing public housing or managing the construction projects. My design won the SIA Architectural Design Award in 1991. Here is the citation published for the award.
CITATION - SIA ARCHITECTURAL DESIGN AWARD 1991
on Clementi Sports Hall by Housing and Development Board
"The dramatic form of the building is entirely appropriate to its setting with the Ayer Rajah Expressway on the south and the parking plaza on the north. The simple sculptural form is sensitively related to surrounding developments allowing for a harmony of geometries and sympathetic ground treatment.
The grammatical permutation of forms is reinforced by the choice of materials and the detailing of the junctioning of the different building elements and the use of the louvred facade cladding."
