What do commercial rents run near 1,1a Thomson Ridge?

Key takeawayURA publishes contracted-rent percentile grids quarterly (latest: 2026Q3) — the benchmark evidence an asking rent should be weighed against.

20 sales

An INDICATIVE AREA yield for District 20 retail — NOT this building's yield, and not any unit's. Commercial rents are published as a district percentile grid, so both halves describe the district.

Priced on STRATA sales only: rent is quoted per unit of lettable area, and commercial land PSF runs far above strata — mixing them would shift the ratio sharply.

Net deducts the 10% non-residential property tax ONLY — not vacancy, maintenance, agent fees, financing, or the 9% GST on purchase.

Submarket: PropKaki's own map from URA's planning subzones (CBD core, City Hall / Bugis, Orchard, city fringe, regional centres, suburban). Brokers draw these lines differently.

Changes of use: URA planning approvals recorded at this building since 2000 (any unit; renewals of a temporary permission not counted). History only — Past approvals are not today's approved use; check with URA's approved-use enquiry before signing.

Company REGISTRATIONS at this address (ACRA), not a tenancy schedule. Registration does not mean the company physically occupies space here, and a low count does not mean the building is empty. Do not describe this as occupancy or vacancy.

Unbuilt GFA cannot be computed here — it needs BCA built-GFA, which covers about 5% of commercial buildings and no industrial ones. Zoning and plot ratio are on record; headroom is not.
