Executive Apartment (HDB) floor plan: size, layout & how to measure it

130–145 m²
typical internal floor area
3 bedrooms + study/utility
layout

Built mainly in the late 1980s–1990s, Singapore Executive Apartments run ~130–145 m² with generous living zones, and often angled walls that make manual measurement tedious.

What the layout looks like

Expect a study or utility room on top of three bedrooms, sometimes a balcony plus an ACC. BAL. (access balcony), and — in stair/corner blocks — walls meeting at non-right angles. Angled walls are where scale-off-the-plan mistakes concentrate; a traced polygon handles them exactly.

Measuring it accurately

The reliable way to measure any executive apt plan is off the drawing itself: calibrate against a printed dimension line, then trace each room along the inside face of the walls. On angled-block plans, never approximate the living room as a rectangle — trace every jog. The 77° corner blocks common in estates like Bangkit and Choa Chu Kang can hide 3–5 m² of error in eyeballed quotes.

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.
