Bedroom types and unit prices
Matched developer-sale transactions by bedroom type: average price, average psf, transacted price range, size range and units sold. Entry prices usually reflect lower floors or less ideal facings.

Figures from matched transactions as at 16 Jul 2026. Averages vary by floor, stack, facing and size — ranges matter more than any single number.
Estimated launch pricing
Estimates are anchored on awarded land cost, construction cost and comparable launches; developers make final pricing decisions. Indicative quantums apply the estimated psf range to typical unit sizes — not a price list.
How D09 resales have performed
Capital appreciation context for The Collective At One Sophia: what profitable sellers of completed condos in the same district realised between Jan 2018 and Apr 2026, and where resale psf has trended.
Read this first: the resale dataset below records profitable matched exits only (Jan 2018 – Apr 2026). Medians describe what profitable sellers made — never the probability of making a gain. Unprofitable exits are not included.

Quarterly median exit psf of profitable resales, Jan 2018 – Apr 2026. Quarters with fewer than 5 exits carry no point; lines bridge to the next qualifying quarter. Dashed line marks The Collective At One Sophia’s current average developer-sale psf — a new-launch price against a resale trend, so compare direction, not levels.

Primary schools within 1km and 2km
MOE primary schools within a straight-line 1km and 2km of this project, with each school's P1 demand tier and phase-by-phase oversubscription ratios from the last completed registration exercise. An address inside a school's 1km band ranks highest whenever that school ballots. Explore every school on the primary schools map.

Distances are straight-line estimates computed from project and school coordinates and shown to 2 decimal places — they are not the official home-school distance. For P1 registration, verify the exact 1km/2km status with the OneMap School Query tool, which applies MOE’s official measurement. No guarantee of accuracy; school demand tiers reflect the 2025 P1 exercise and can change year to year. Full map and methodology: primary schools near new launches.
