Land Sizes, Height Limits, Setbacks & What You Can Build
Landed Property Buyer’s Guide (2025)
When buying landed property in Singapore — whether it’s a terrace, corner terrace, semi-detached home, detached house, or a Good Class Bungalow (GCB) — understanding URA’s building guidelines is just as important as knowing the land size.
Two plots may have the same land area, but the allowable heights, envelope control rules, and setback requirements can make one plot far more valuable than another.
This guide breaks down the essentials for buyers who want clarity before committing to a major investment.
- Terrace Houses — Entry Point Into Landed Living
Minimum land size:
* 150 sqm (approx. 1,615 sqft)
Minimum width:
* 6m
Key considerations for buyers:
* Typically up to 2 or 2.5 storeys, depending on URA zoning
* Rear, front & side setbacks must be respected
* Envelope control limits may affect attic height and roof profile
* Terraces in mature estates often have stronger long-term value due to scarcity
- Corner Terraces — Extra Land, Extra Flexibility
Corner terraces often offer:
* Larger land sizes
* More light, ventilation & privacy
* Potential for bigger extension footprints
Because they border a side road or open space, side setbacks differ and can unlock more buildable area — especially useful for families wanting bigger bedrooms or an extended kitchen.
- Semi-Detached Homes — Balance of Space & Privacy
Semi-Ds typically allow:
* Wider frontage
* More flexibility in reconfiguration
* A higher sense of privacy compared to terraces
Setbacks matter here, especially the open-to-sky side which must remain free for ventilation under URA rules.
Buyers should check:
* Whether the existing structure can support an attic
* Whether extensions comply with envelope control
* If the neighbour’s build-up affects light or privacy
- Detached Homes — Full Freedom on a Single Plot
Detached houses enjoy:
* Maximum privacy
* Largest buildable footprint
* Highest configuration flexibility
Setback requirements:
* Larger required distances on all sides
* Significant impact on GFA potential depending on land shape
Irregular or pie-shaped plots can reduce effective buildability even if land area is large.
- Good Class Bungalows (GCBs) — Singapore’s Pinnacle of Landed Homes
GCBs require:
* Minimum 1,400 sqm land size
* Located within designated GCB areas
* Strict planning controls to preserve greenery & low-density character
Typically capped at 2 storeys, though attics may be permitted within envelope guidelines.
- Understanding URA Setbacks — The Most Misunderstood Factor
Setbacks determine how much of the land you can actually build on.
Front setback
Usually around 7.5m, varies depending on road category.
Rear setback
Typically 2–3m, depending on height and zoning.
Side setbacks
* Terrace: constrained due to party walls
* Corner terrace / Semi-D: generally 2–3m from open side
* Detached: more stringent, often >3m on each side
Arterial road setbacks
If the property fronts an arterial road → larger setbacks apply, which can significantly affect GFA.
- Height Limits & Envelope Control
Most landed homes fall under:
* 2 or 2.5 storeys + attic
* Attic must follow the 45-degree roof angle rule
* Maximum building height varies by location & street profile
Envelope control replaces rigid storey counts with a 3D “building envelope” that regulates massing, roofline, and extensions.
- Why These Guidelines Matter for Buyers
Two plots can be the same size on paper but have:
* Different build-up potential
* Different privacy levels
* Different extension allowances
* Different long-term resale performance
Understanding setbacks, height limits, and envelope rules ensures buyers don’t overpay for land that can’t achieve their desired layout or build-up potential
