The Design, Build and Sell Scheme was introduced by the Housing and Development Board in 2005. Flats built under the scheme were meant for public housing and built by private developers. They were built with supposedly better designs and mostly in matured estates such as Tampines, Ang Mo Kio and Bishan. There were 13 DBSS projects, totaling 8,533 units. The scheme attracted public outrage when a series of five-room DBSS flats developed in Tampines by Sim Lian Group Limited opened for sale at S$880,000, significantly more expensive than most middle-class families could afford. As HDB did not control the pricing of DBSS units being sold, the scheme was poorly received and subsequently suspended indefinitely.
