Written Answer by Ministry of National Development on take-up rate of 3Gen HDB flats

Jul 8, 2019

Mr Liang Eng Hwa: To ask the Minister for National Development in respect of the take-up rate of 3Gen HDB flats at recent BTOs, what are the reasons for the current response and what does HDB intend to do for those 3Gen flats that remain unsold after repeated Sale of Balance Flats exercises.


Three-Generation (3Gen) flats are specifically designed for multi-generation families who wish to live under one roof. The response to 3Gen flats has been encouraging, with about seven in ten units booked since such flats were introduced in 2013.

In general, the take-up rate of flats in each Build-To-Order (BTO) project depends on many factors, including distance from the city centre, proximity to transport nodes, and amenities in the neighbourhood.

Like all other balance flats, unsold 3Gen flats are subsequently offered for sale under the Sale of Balance Flats and Re-Offer of Balance Flats exercises. Unselected units from these two exercises will then be made available for open booking throughout the year.

HDB will continue to monitor the demand for 3Gen flats and calibrate the supply accordingly.
