Every GCB is a Detached house (URA's structural classification), but not every Detached house is a GCB. The GCB designation requires three additional things: (1) location within one of 39 gazetted GCB Areas, (2) plot ≥ 1,400 sqm, and (3) the planning-control package (2-storey cap, 35% site coverage, citizen-only ownership). A Detached home in Bishan or Bukit Timah is not a GCB regardless of plot size.
The classification hierarchy
- Landed property: Umbrella term covering Terrace, Semi-Detached, Detached, and a few strata variants.
- Detached: A free-standing house with no shared walls. URA's structural classification.
- Bungalow: Singapore parlance for a Detached house on ≥~400 sqm. No strict legal definition.
- Good Class Bungalow (GCB): Detached house in a gazetted GCBA on ≥1,400 sqm, with the planning-control + citizenship-restricted regime.
Why the distinction matters
- Ownership: A non-GCB Detached can be owned by a foreigner with LDAU approval. A GCB cannot, except in extreme PR cases.
- Redevelopment: A non-GCB Detached may support more than 2 storeys if zoning allows. A GCB is capped at 2.
- Price: Non-GCB Detached in D9/D10 can hit $15-30M but rarely matches the trophy GCB tier.
- Buyer pool: Non-GCB Detached has a broader pool; GCB is citizens-only.
