See Prices by Floor & Stack

Tower View shows how transacted prices move across a building. For a condo, it draws the block as a floor × stack grid where each cell is a transacted unit, shaded by price per square foot. For an HDB block, it shows median resale prices across storey bands and flat types. It surfaces the floor premium, the priciest stack and the full storey gradient for any Singapore project.

The floor premium is how much more, in percentage terms, higher floors transact at compared with lower floors of the same building — measured by median PSF between the top and bottom storey bands. Higher floors usually command a premium for views and light; Tower View quantifies it per project.

From URA caveat data. Each private sale caveat states the unit number (in #floor-stack form, e.g. #12-07) inside the address, so the floor and stack are recovered directly from the transaction record — not estimated.

Tower View only shows units that have actually transacted. An empty cell means there is no caveat on record for that floor and stack — not that the unit doesn't exist. Denser projects (more transactions) produce a fuller grid.

Yes. HDB resale records don't include unit numbers, so HDB uses a storey-band × flat-type grid instead: rows are storey ranges (e.g. 10 to 12) and columns are flat types (3-room, 4-room, 5-room), with the median resale price in each cell — plus the block's true height and unit mix.

The stack (the vertical column of units sharing a unit number, e.g. #xx-07) with the highest median PSF in the most-transacted block. Stacks differ by facing, view and layout, so the priciest stack is often the best-facing column of the development.
