A sofa that looks right in a showroom can be physically impossible to get through a standard HDB corridor unit door, and furniture ordered without confirming lift booking windows can sit in a delivery queue for weeks. Here's how to plan around both.
Standard HDB doorway and corridor widths
Most HDB unit entrance doors are around 850mm-900mm wide, and internal bedroom doors are often narrower, around 700mm-800mm. Corridor units add a second constraint: the common corridor width and any turns near the lift lobby. Before ordering anything large, such as a 3-seater sofa, a queen bed frame, or a wide wardrobe, check the product's packed dimensions, not just the assembled dimensions, against your narrowest doorway, not just your front door.
“Measure the narrowest doorway between the lift and the room, not the front door. That's the dimension that actually decides whether a piece gets in.”
Lift booking and delivery timing
Many HDB blocks require residents to book the lift in advance for large deliveries, particularly for upper floors or blocks without a dedicated cargo lift. If you're coordinating a BTO move-in, confirm your block's lift booking process with your Town Council or MCST before locking in a delivery date. A furniture delivery scheduled without a matching lift booking is the single most common cause of last-minute rescheduling.
3-room vs 4-room layouts: what changes
- 3-room flats (typically 60-65 sqm): bedrooms often fit a queen bed only if a wardrobe is kept compact or built-in; a loft bed or storage bed frees significant floor area in the second bedroom.
- 4-room flats (typically 90-95 sqm): more flexibility for a full dining set plus a 3-seater sofa, but living rooms are still narrower than condo equivalents. Measure the distance from sofa-back to TV console wall before buying a deep-seat sofa.
- Both layouts: corridor and lift-lobby width near the unit, not just the unit's internal floor area, is what actually determines whether a piece can be delivered intact.
Checking fit before you order
Avior's Room Planner lets you upload a floor plan or enter your room dimensions to visualise how a specific piece sits in your space before ordering. It's a useful first pass, but always cross-check the listed product dimensions against your actual doorway and corridor measurements. Visualisation tools account for floor area, not always door swing and corridor turns.
