The city-state’s Urban Redevelopment Authority said on Tuesday it has received an application from Tunku Ismail, who is also the Regent of Johor, to develop his 16.6 hectares of land into low-rise, low-density housing, including GCBs, with a gross plot ratio of 1.4.
After reviewing the application, the agency proposed rezoning the land parcels for residential use, adding that part of the site zoned “residential” would also be designated as a GCB Area if the development plan is approved.

GCBs are the most coveted type of landed housing in Singapore. They are confined to specific zones, require a minimum land size of 1,400 square meters, and are capped at two stories under URA rules. There are fewer than 3,000 such properties in 39 designated areas across the city-state.
Tunku Ismail, the eldest of six children of Sultan Ibrahim, is also the Regent of Johor. The Johor royal family’s wealth was estimated at US$5.7 billion in 2024, with their property holdings in Singapore making up a sizable portion of that fortune.
