See Prices by Floor & Stack
Search any Singapore condo or HDB block to see how transacted prices move across storeys and stacks — the floor premium, the priciest stack and the full storey gradient, from URA caveat data.

indicative asking range for a specific unit, from this block's stack & floor premia
Indicative only — stack #01's median PSF adjusted for the floor band, applied to its typical size. Not a valuation.

Unit-level transactions are URA caveats with a stated unit number (#floor-stack). Stacks re-use numbers across blocks, so the grid is per block. Landed and basement units are not shown.
What Tower View does
Tower View shows you how price moves within a single building — floor by floor and stack by stack. For a Singapore condo it maps the floor premium (how much more a higher floor costs) and the priciest stacks; for HDB it shows the storey gradient by flat type. It's how you tell whether a specific unit is well-priced for its exact floor and facing, using real transacted prices rather than a blanket project average.
Floor premium & best stacks
See how much each floor adds and which stacks command the highest prices.
Condo grids & HDB storeys
A floor-by-stack grid for condos, and a storey gradient by flat type for HDB.
Priced from real deals
Built from recorded transactions, so the gradient reflects what units actually sold for.
Floor and stack change the price — by how much?
How much a higher floor or better stack is worth, and if a unit's priced right.
PropKakiEach floor adds roughly $4–6k; the pool-facing stacks sell about 7% higher.
Tower View — frequently asked questions
What is Tower View?+
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.
What is the floor premium?+
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.
Where does the unit-level data come from?+
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.
Why are some cells in the grid empty?+
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.
Does Tower View work for HDB flats?+
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.
What is the priciest stack?+
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.
