Site Coverage

Check the guidelines relating to site coverage for bungalows (or detached houses).

Last updated 7 June 2026

Bungalows (or Detached Houses) are subject to a two-tier site coverage control as follows:

  1. Site Coverage

    • This is measured based on the footprint of the building and coverage of all building features (raised 1m or more above ground level) when viewed from above.

  2. Sub-control

    • The sub-control is for areas computed up to the external façade of the building, including features such as balconies, planters, bay windows and roof terraces. 50% of the car porch roof area will also be counted towards the sub-control.

    • Sun-shading features (e.g. roof eaves, ledges, trellis, horizontal and vertical fins), including those with vertical supports (e.g. pavilions, covered patio), are excluded from the sub-control.
