Lease and eligibility context

About 86 years remain on the 99-year lease, based on its 2013 commencement year. This year-level figure is approximate.

A standard flat completed around 2011 would usually reach its 5-year MOP around 2016. 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.

204 flats: 104 × 2-room, 50 × 3-room, 50 × 4-room.
