Flats and Condominiums

Maximum Number of Dwelling Units

The formulae to determine the maximum number of dwelling units (DUs) shall not apply to HDB flats and Serviced Apartments, and developments within the Central Area (PDF, 436 KB).

As a guide, all self-contained DUs island-wide shall be more than 35sqm nett in internal area.

The formulae in the following tabs for calculating the maximum allowable number of DUs are intended to derive an upper bound figure¹. The actual number of DUs that may be supported in any development shall be assessed based on the site context, existing site conditions and the impact on the local infrastructure. URA shall assess the overall layout, design and unit sizes of the residential development proposals, and may add other requirements where necessary to protect the quality of the living environment.

There shall be provision of a good mix of unit sizes including larger DUs that can cater to the needs of larger families. An example is a development where about 20% of the DUs have a nett internal area of at least 100sqm, excluding voids, balconies, air-conditioner ledges and other external areas, and units of nett internal area less than 50sqm shall not exceed about 20% of the proposed DUs¹.

¹ These guidelines shall apply to the residential component of mixed-use developments (e.g. Residential with Commercial at 1^st Storey or Mixed Commercial and Residential developments)
