PlanTape PlanTape Jumbo flats are two adjacent Singapore HDB flats converted into one — commonly in Woodlands, Yishun and Tampines — spanning roughly 145–190 m² depending on the pair joined.
Because each jumbo is a one-off conversion, no two plans are alike: expect duplicated kitchens turned into utility zones, non-standard corridors at the join line, and occasionally two household shelters. The official floor plan is the only reliable source of truth.
The reliable way to measure any jumbo plan is off the drawing itself: calibrate against a printed dimension line, then trace each room along the inside face of the walls. Get the post-conversion plan from HDB rather than measuring the two original flats — walls at the join were hacked or added, and old plans will mislead the quote by several square metres.
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 145–190 m² of internal floor area, with 4–5 bedrooms (two flats joined). Exact size varies by launch year and block type — the floor plan for your specific unit is the only reliable source.
