An INDICATIVE AREA yield for District 1 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.

Read the figures right

Year of completion is not on record for this building. Building age cannot be stated.

Total units: the strata units in the building's MCST (BCA's register) — strata lots, not tenancies; a single-owner building can be one lot. Units with a recorded sale (URA caveats) are a separate figure.

Strata lots: the lot count in the development's MCST (BCA's register) — the whole development, homes included where it is mixed; a single-owner mall or tower can be one lot.

Strata formed: the year the MCST was set up (BCA's register). NOT the year the building was completed — an MCST forms after TOP, sometimes years later. Never state it as the building's age.

Managing agent: as BCA's MCST register names it; it can change between register updates.

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. Never say a use is allowed, permitted or approved for a unit, and never say a use would be approved.

Station taps: average weekday fare-card taps in and out at the nearest MRT/LRT station (LTA DataMall). People passing the station's gates, not people visiting this building.

Foot-traffic score: PropKaki's relative score from nearby MRT and bus taps, workers and residents around (and, for retail, competing malls), ranked against buildings of the same kind. A percentile, not a count of people.

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.

Storeys: from OpenStreetMap (© OpenStreetMap contributors), volunteer-mapped, not an official record. Shown only because no official or listed floor count is held for this building.
