Planning Permission, Step by Step
A landed submission goes to the planning authority for written permission first, then to the building authority for structural and building plan approval, then through to TOP and CSC at completion. On a straightforward detached rebuild the first approval 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.
