Inside the 39 Good Class Bungalow (GCB) Zones

Occupying the absolute apex of Singapore's social and financial hierarchy, Good Class Bungalows (GCBs) represent an ultra-exclusive asset class of.

Occupying the absolute apex of Singapore's social and financial hierarchy, Good Class Bungalows (GCBs) represent an ultra-exclusive asset class of approximately 2,800 estates islandwide.

Guarded by the Urban Redevelopment Authority (URA) through rigorous planning directives, GCBs are protected from dense urban subdivision to preserve the verdant, low-density green lung character of Singapore’s prime estates.

Acquiring and reconstructing a GCB requires mastering the 1,400 sqm cadastral threshold, 35% site coverage limits, and statutory NParks Tree Conservation Area laws.

Executive Rules of Good Class Bungalows

The 39 Designated Areas: GCB status is tied strictly to geography, not architectural style. Properties must sit within one of the 39 designated Good Class Bungalow Areas gazetted by URA (e.g. Nassim Road, Cluny Park, Queen Astrid Park, Ridley Park, Leedon Park, Oei Tiong Ham Park).
The 1,400 Square Meter Rule: GCB plots cannot be subdivided if any resulting lot falls below 1,400 square meters (15,070 square feet). If an existing historical GCB plot sits on 1,200 sqm, it cannot be rebuilt with subdivision rights.
Maximum 35% Site Coverage: The physical building footprint (including outhouses and covered porches) cannot exceed 35% of the plot area. At least 65% of the land must remain lush, unbuilt greenery.
Strict Citizen-Only Ownership: Under the Residential Property Act, non-Singaporeans cannot own GCBs. Rare approvals granted to exceptionally contributing Singapore PRs carry strict conditions against flipping.

Protected Girth Threshold: Any tree with a trunk girth exceeding 1.0 meter (measured 0.5 meters from ground level) is statutorily protected.
Mandatory Arborist Assessment: Prior to any demolition, excavation, or reconstruction, the owner must submit a formal Tree Protection Plan authored by an ISA-certified arborist to NParks.
Criminal Liability: Felling or damaging the root system of a protected tree without NParks clearance incurs statutory fines up to S$50,000 per violation.
