Three residential sites will be rolled out for sale under the first half Government Land Sales (GLS) programme.

Together, they can yield about 1,300 residential units, said the Urban Redevelopment Authority and Housing Development Board in a joint statement on Thursday.

Two of the parcels, at Yishun Street 51, are for executive condominiums put up for sale under the confirmed list.

One of the EC sites, Parcel A, has a maximum gross floor area (GFA) of 50,302 square metres and can yield 490 units.

The other site - Parcel B- can have 520 units and has a maximum GFA of 51,139 sq m.

A plum residential site at Margaret Drive, however, will be made available on the reserve list today. The 4,810 sq m site can yield 275 units.

Confirmed sites go on sale regardless of interest. Those on the reserve list are put up for tender only if developers submit an acceptable initial offer.

All sites are on 99-year leases.

Tenders close on May 22 for both EC sites.
