How big is an HDB flat of each type?
The median floor area of HDB flats resold from Jul to Sep 2026, by flat type, from HDB's resale records. The Floor Plan Finder holds condo floor plans; it does not hold HDB layouts.
| Flat type | Median size | Middle half | Resales |
|---|---|---|---|
| 2-room | 47 sqm (506 sq ft) | 44–47 sqm | 156 |
| 3-room | 67 sqm (721 sq ft) | 65–69 sqm | 1,216 |
| 4-room | 93 sqm (1,001 sq ft) | 92–101 sqm | 2,488 |
| 5-room | 117 sqm (1,259 sq ft) | 112–122 sqm | 1,369 |
| Executive | 146 sqm (1,572 sq ft) | 141–148 sqm | 360 |
What the Floor Plan Finder does
The Floor Plan Finder shows the unit floor plans of a Singapore condo — search by street address, postal code or project name and see every unit type's layout, grouped by bedroom count with sizes and features. Where a project's unit index is available, enter a unit number like #12-25 to jump straight to that exact unit's plan. Plans are digitised from developer brochures, each tagged with its layout class (dual-key, penthouse, loft, ground-floor PES) and features like a study, helper's room or private lift.
Search by address
A street address, 6-digit postal code or condo name — all resolve to the development's plans.

How do I find the floor plan for a Singapore condo?
Enter the condo's address, postal code or project name in PropKaki's Floor Plan Finder — free, no account needed. It returns the development's unit floor plans grouped by bedroom count, each labelled with its unit type, size in square feet and layout features. The plans are digitised from developer brochures, so they're the official layouts rather than an agent's sketch.
Can I find the floor plan for my exact unit number?
Yes — for projects with a unit-level index, enter your unit number (for example #12-25) after looking up the project, and the Floor Plan Finder maps it to the developer's unit type and shows that exact plan. The mapping comes from the developer's schedule of units in the brochure, cross-checked against per-unit records, so most units resolve directly to their layout.
What does a dual-key or dumbbell layout mean on a floor plan?
A dual-key unit has two self-contained sections — each with its own entrance and kitchenette or bath — sharing one main door and title, popular for renting one half out. A dumbbell layout places bedrooms at opposite ends with the living and dining in the middle, giving both bedrooms privacy. PropKaki tags each floor plan with these layout classes, plus features like a study, helper's room, private lift or PES, so you can compare layouts across projects.
What is a PES or ground-floor garden unit?
PES stands for Private Enclosed Space — the fenced patio or garden attached to a ground-floor condo unit. It's outdoor space you use exclusively but it's usually counted in your unit's strata area, so a PES unit's floor area reads larger than its air-conditioned interior. The Floor Plan Finder labels these plans as ground-floor PES layouts so you can spot them before viewing.
Why does my condo's floor plan show a household shelter or bay window?
A household shelter (often marked HS) is the reinforced room required in Singapore homes built from the late 1990s — most owners use it as a store room. Bay windows and planter boxes appear mainly in condos completed before around 2009, when they stopped being exempt from gross floor area rules; they add to your strata area, which is why older layouts often show them. Floor plans in the finder carry these details, which is useful when comparing usable space between projects of different eras.
Which projects are covered, and what if mine isn't yet?
Coverage is growing project by project as PropKaki digitises developer brochures — condominiums first, with more added regularly. If your project isn't covered yet, the finder tells you honestly rather than showing someone else's layout, and you can still see the project's details, transactions and amenities through PropKaki's other free tools or ask the PropKaki assistant directly.
Are these floor plans accurate enough to renovate or buy from?
The plans are digitised from official developer sales brochures, so layouts, orientations and unit-type labels reflect the developer's own drawings. Brochure plans are indicative, though: dimensions are approximate, mirrored variants exist, and developers occasionally revise layouts during construction. Use them to shortlist and compare — then confirm against the developer's title-deed plan or a site measurement before committing to renovation works or a purchase.
