Commercial

Retail Unit Size and Internal Corridor Width

Retail Unit Size

The average retail unit size shall not be less than 50sqm. Average retail unit size is determined using the following formula:

The width requirements for internal corridor are dependent on the number of commercial units it serves, and are detailed in the table below.

Internal Corridor Width

Type of Corridor Primary Corridor1
(with expected high footfall) 		Secondary Corridor2
Single Loaded
(single row of retail units) 		Minimum 2.4m Minimum 2.0m
Double Loaded
(retail units on both sides) 		Minimum 3.0m Minimum 2.4m

1 Primary corridors are thoroughfares where high foot traffic is expected. These are typically the routes between the main entrances and exits of the development. Each commercial development shall provide at least 1 primary corridor and indicate this on plan.

2 Secondary corridors refer to all other corridors.

For other types of corridor width requirements, refer to relevant guidelines (eg. BCA Approved Document and SCDF Fire Code). Where a corridor is required to fulfil other functions (eg. Accessible Corridor), the minimum corridor width shall take reference from whichever corridor width requirement that is greater.

Note: A wider corridor width may be required for corridors with expected heavy pedestrian traffic.
