Singapore's biggest public housing project is also one of this year's best.

Casa Clementi, a 10-block development of 2,234 flats, has picked up two top Housing Board awards this year for being well designed and well built. Its features include 15,000 sq m large landscaped deck with playgrounds and exercise corners for residents. The contractor, Straits Construction, was also commended for minimising noise pollution to the nearby Nan Hua High School by installing curtains and barriers.

A total of 18 HDB awards will be presented to architects and contractors on Tuesday.

Punggol Breeze, a 12-block HDB project of 964 units with a long roof garden, also bagged two design and construction awards.
