Lease and eligibility context

About 91 years remain on the 99-year lease, based on its 2018 commencement year. This year-level figure is approximate.

A standard flat completed around 2017 would usually reach its 5-year MOP around 2022. 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.

108 flats: 48 × 4-room, 60 × 5-room.
