At about 110–113 m², the 5-room HDB flat adds a dining area or study zone to the 4-room template — more floor, more skirting, and more places for a quote to go wrong.
The extra space typically shows up as a distinct DINING zone beside the kitchen or a wider living room. Open-plan living/dining areas meet with no dividing wall, so a measured plan needs a sensible split line between the two zones if the client wants per-room breakdowns.
The reliable way to measure any 5-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. Where living and dining are open-plan, pick the natural dividing line (usually flush with a kitchen wall) and keep the two polygons edge-to-edge with no overlap — your totals stay honest and the per-room CSV still makes sense.
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 110–113 m² of internal floor area, with 3 bedrooms + extra living space. Exact size varies by launch year and block type — the floor plan for your specific unit is the only reliable source.
