3-room HDB flat floor plan: size, layout & how to measure it

60–65 m²
typical internal floor area
2 bedrooms
layout

A staple of older Singapore estates like Toa Payoh, Ang Mo Kio and Bedok, typically 60–65 m² with two bedrooms — a very common size for skirting and flooring repackaging jobs.

What the layout looks like

Older 3-room blocks (New Flat / Improved / Model A variants) differ meaningfully: corridor-facing units often have a long access balcony, and improved layouts add a separate WC and bathroom. Many pre-1980s plans have rougher linework, so AI-assisted tracing saves the most time on these.

Measuring it accurately

The reliable way to measure any 3-room hdb plan is off the drawing itself: calibrate against a printed dimension line, then trace each room along the inside face of the walls. On corridor-type plans, the ACCESS BALCONY strip is common property — include it only if the quote covers it. Check whether the plan marks "ROUGH FLR. FIN." rooms; those often need levelling allowances in the quote.

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.
