What has Thomson Ridge sold for?

Key takeaway1 transaction is on record since 1995, most recently in Sept 2007 — too few to support a median, so the deals themselves are listed instead.

Date	Use	Price	Area	PSF

URA's percentiles of RETAIL rents (shop, F&B, entertainment, health & fitness) across every lease stamped with IRAS on this STREET in the quarter — the street's figure, not this building's rent and never a unit's. Retail rent swings with floor and frontage, so the spread matters as much as the median. A median needs at least 2 buildings and 3 contracts (percentiles need 4); a blank means below that threshold, not zero.

What's been approved at Thomson Ridge?

Per URA circular DC23-08, Appendix A (2 Oct 2023: no new eating houses in shophouses on listed stretches). A planning guideline for the area, not a decision on any unit; it applies to new eating houses and bars, not to one already approved.

How does Upper Thomson Road price?

Strata sales on the street (5y)

Too few strata sales on this street to support a median — the count is shown without one.

Street figures cover strata deals only — land and strata PSF are not comparable.

What do commercial rents run near Thomson Ridge?

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.
