Lease and eligibility context

About 70 years remain on the 99-year lease, based on its 1997 commencement year. This year-level figure is approximate.

A standard flat completed around 1996 would usually reach its 5-year MOP around 2001. The actual MOP starts from each owner’s key collection date, and special schemes can differ. Check HDB’s rule ↗

Indicative only. Check your dates and eligibility with HDB, CPF and your conveyancing adviser.

87 flats: 66 × 4-room, 21 × 5-room.
