What is a jumbo flat and the HDB conversion scheme?

A jumbo flat is a type of housing unit in Singapore created by combining two adjoining three-room or smaller flats. This conversion scheme was introduced in 1993 to address the issue of unsold smaller flats during the 1980s. The Housing and Development Board (HDB) is currently reviewing the scheme following concerns raised about a jumbo flat listed for sale at $2.18 million in Telok Blangah.

To qualify for a jumbo flat, eligible owners must combine their flat with a neighboring unit and obtain HDB's assessment on the structural feasibility of the conversion. After approval, the two units can be combined into a single flat under one lease, which can then be sold on the open market after a five-year minimum occupation period (MOP).

In order to proceed with the conversion, the household must consist of a married couple or a family of parents and children. If the conversion is approved, the owner must hire a registered renovation contractor to create a 1m by 2m opening between the units and engage a licensed contractor to remove water, gas, and electricity meters for one of the two units.

As of now, there are approximately 2,900 jumbo flats in Singapore out of a total of about 1.1 million HDB flats. These larger units offer more living space, with sizes ranging from 1,400 sq ft to over 2,000 sq ft, providing a solution to the demand for larger living accommodations in the housing market.
