Mr Chua Kheng Wee Louis asked the Minister for National Development (a) what is the current average site expiry in years, for HDB flats introduced under the Parenthood Provisional Housing Scheme (PPHS); and (b) in each year over the last five years, what is the breakdown of PPHS units by flat type, such as flats under the Selective En bloc Redevelopment Scheme, unsold HDB units, HDB rental units and polytechnic staff apartments.
Mr Desmond Lee: Flats under the Parenthood Provisional Housing Scheme (PPHS) have various site expiry dates. Out of the current stock of 1,430 PPHS flats:
a) 900 (63%) are HDB flats such as unsold flats and public rental flats, which generally have longer and more flexible tenures of more than three years and can be used for PPHS as long as they are not required for more urgent uses; and
b) 450 (31%) are vacated Selective En bloc Redevelopment Scheme (SERS) flats and 80 (6%) are polytechnic apartments, which generally have shorter tenures of around two to three years, and must be returned when the sites are needed for redevelopment or when the leases are up.
The breakdown of PPHS flats from various sources in each of the past five years is shown in Table 1.
