Planning Permission, Step by Step
A landed project goes to URA for planning permission first, then to BCA for building plan and structural approval, then through to TOP and CSC at completion. On a straightforward detached rebuild, written permission typically takes six to twelve weeks. Queries reset that clock, which is why the drawings matter more than the covering letter.

Setbacks and Envelope Control, Explained
Landed housing in Singapore is controlled by an envelope rather than a plot ratio, so the maximum shape of a house is fixed by its plot before any design begins. Outside Good Class Bungalow Areas, the main building is set back 2 metres from side and rear boundaries; from the road it is 7.5 metres on most residential roads, 12 on a Category 2 road and 24 on a Category 1. Height is 12 metres in a two-storey area and 15.5 in a three-storey one.

Conservation Properties: What Changes
On a conserved property URA's principle is the 3R — maximum Retention, sensitive Restoration and careful Repair — so the original structure and architecture are kept, and new work goes where the rules for that area allow it: in a residential historic district such as Emerald Hill or Blair Plain, a rear extension lower than the main roof; in a secondary settlement such as Joo Chiat, a rear extension up to the area's height. Approvals take longer and the palette is narrower, and the design problem is more interesting rather than less.

BCA Requirements and Building Plan Approval
After URA planning permission, a landed project moves into building control with BCA: building plan and structural plan approval, then a permit to commence before any work on site, inspections during construction, and TOP and CSC at the end. Planning decides what the house may be; building control decides whether it can safely be built.

Common Approval Mistakes, and How to Avoid Them
Most approval problems are self-inflicted and discovered late. The recurring ones are designing before the envelope is confirmed, treating a neighbour's house as a precedent, inheriting unauthorised works, working from inaccurate drawings, missing site constraints, changing the design after approval, and building a programme that assumes first-time approval.
