Commercial

The number of storeys for commercial developments is guided by the building height plan.

If the storey height is not specified in the building height plan, the number of storeys shall be evaluated by taking into consideration the location, site context, site topography, and impact of the commercial development on the surroundings.

Basement storeys that protrude more than 1.0m above ground level on any side shall be counted as a storey.

Floor-to-floor Height

The maximum floor-to-floor height for commercial developments is 5m, including mezzanine floor.

Variations in floor-to-floor height are subject to evaluation depending on the use and location of the floor. If permitted, the proposed building height shall not exceed the maximum building height control computed based on the permitted number of storeys.

Unless otherwise stated, the overall building height¹ of commercial developments is subject to compliance with the technical height controls of the relevant agencies such as Civil Aviation Authority of Singapore (CAAS) and the Defence Science and Technology Agency (DSTA). 

¹ Building height is based on Singapore Height Datum (SHD). 

Additional Height for Predominant Sky Terrace Storeys

Predominant Sky Terrace Storeys (PSTS) are floors where the sky terrace areas within the 45-degree line occupy at least 60% of the floor plate. 

If the proposed number of storeys in the development is more than 7 storeys, commercial developments with PSTS may be allowed additional building height depending on the number of storeys proposed as shown in the table below:

Additional Building Height based on Proposed Storey Height

The additional building height may only be distributed to the sky terrace floors within the development. Spaces for M&E services located directly beneath the sky terrace floor may be included in the additional height.

The overall building height is subject to technical height controls.

The additional building height shall not apply to:

1. Developments within Conservation Areas and sites with National Monuments;
2. Developments with height control of 6 storeys or less; or
3. Developments with special controls e.g. areas with street block plans.

In addition to (a) – (c), any additional building height will be subject to evaluation for developments adjacent to conserved buildings or in urban design areas with site-specific height considerations.
