PlanTape PlanTape Two-storey HDB living at ~139–155 m². Maisonette plans come as two separate floor drawings, which doubles the measuring work — and the room for error.
The lower floor holds living, dining, kitchen and a WC; bedrooms and bathrooms are upstairs. The internal staircase is not floor area for most flooring quotes (it is usually quoted separately per tread), and the double-volume void in some layouts must be excluded upstairs.
The reliable way to measure any maisonette plan is off the drawing itself: calibrate against a printed dimension line, then trace each room along the inside face of the walls. Measure each storey as its own plan and keep the staircase and any void out of the upstairs polygons. Export the two CSVs and sum — or keep them separate if the client prices staircase cladding independently.
PlanTape does the tracing for you — AI detects every labelled room and the scale line in under two minutes, you fine-tune the corners, and the per-room areas and skirting perimeters export as a CSV.
Typically 139–155 m² of internal floor area, with 3–4 bedrooms over two storeys. Exact size varies by launch year and block type — the floor plan for your specific unit is the only reliable source.
