How to widen interior doorways for wheelchair access
A wheelchair-accessible route depends on a continuous path through the home. The doorway is only one pinch point: floor level, approach space, door swing, furniture and turning room determine whether a chair can pass and stop safely.
Australian homes make the task highly variable. Narrow passages in Sydney terraces and compact plans in Melbourne apartments can conceal different walls, services and turning constraints, even when two doors look identical on a plan.
Use Australian metric measurements, and treat AS 1428.1 and the National Construction Code as references rather than a substitute for individual advice. A project in Sydney, Brisbane or Adelaide may still require council consent, owners corporation approval in NSW or body corporate approval in Victoria, especially in a rental, apartment or heritage building.
Start with a full mobility route
Begin with the narrowest clear opening along the route, not the nominal door-leaf width. Measure between the door stop and the opposite frame with the door open, then note any architrave, floor build-up or projecting handle. Under Australian accessibility guidance, 800 mm is a commonly cited minimum clear opening, but a user may need 900 mm or more for comfort and manoeuvring.
Record the approach and turning space on both sides, plus thresholds and space beside a bed, desk or toilet. Dimensions alone cannot reveal whether a powered chair will approach the doorway squarely, reverse through it or recover after a turn.
In an open-plan home, the widened opening may also change how cabinetry projects into the travel path; open shelving ideas demonstrate how storage choices can keep that route calmer and less cluttered. This matters when a dining chair, appliance door or bin becomes the next obstruction.
Choose a doorway system that fits
The main structural choices are to widen the framed opening, install a sliding or pocket door, or change the swing and hinge arrangement. If the passage doubles as a garage or workshop route, garage flooring upgrades show how hard-wearing surfaces and wall storage can keep the widened threshold clear of stored equipment and trip hazards.
A pocket slider can provide a wide, unobstructed passage, but it needs a cavity or surface-mounted track and careful planning around wiring, studs and wall finishes. Relocating a door to swing outward may avoid moving the frame, although it can conflict with a corridor, another leaf or an escape route. Offset hinges offer only a modest gain and cannot rescue an extremely narrow frame.
Australian hardware retailers such as Bunnings stock common frames, lever handles and hinges, while joinery suppliers can make wider or heritage-matched units. Check the assembly: a broad leaf in an old frame may add little usable clearance, and non-standard sizes can affect seals, locks and floor finishes.
Resolve approvals before demolition
Check the wall before demolition. Ask a builder or building surveyor whether it is load-bearing and whether the opening contains a lintel, plumbing, electrical wiring, insulation or fire-rated construction. In brick-veneer and weatherboard homes, the lining may conceal timber studs, while masonry walls require a different approach.
Approvals depend on the site and work. A private owner may be able to alter a non-structural internal partition, but a unit owner should check the strata contract, and a landlord should obtain written consent. Melbourne apartments may have fire doors and communal escape rules; Adelaide heritage cottages may need advice from a heritage architect and local council before original trim is changed.
Use an appropriately licensed tradesperson for service relocation and obtain structural input where a header is affected. Record existing conditions, keep product certificates and check that insurance or warranty conditions will not be breached.
Fit the opening to everyday use
Once the route and approvals are settled, remove architraves carefully, expose the framing and create the opening. A builder will install or resize the header, jamb and stop, then patch the lining. Dust control and protection of the occupied room matter during this stage.
Match the new reveal, architrave and flooring to adjoining surfaces rather than relying on a narrow filler strip. Use a flush or gently bevelled threshold, smooth running clearance and a lever handle that can be operated with one hand. Position the stop and latch so the chair cannot catch a projecting edge.
Plan the doorway around the resident’s whole routine, not only transfers at the door. Communication is another part of independent access: stuttering communication resources can help relatives and support workers understand that a delayed or altered response should not be treated as consent. An occupational therapist can also advise on approach direction, reach and equipment placement.
Compare the main doorway options
The three main approaches have different effects on space, structure and daily operation. The most useful comparison is therefore based on usable clearance and fit, not simply on the finished width of the door panel.
A conventional hinged door often feels most familiar, while a slider changes the wall build-up and a relocated swing changes where the door occupies the room. These differences affect furniture placement, maintenance and the remaining turning space.
| Option | Main effect | Best fit | Checks before work |
|---|---|---|---|
| Widen the framed opening | Keeps a conventional hinged door and usually offers the largest clear width | Internal walls where framing can be altered | Load-bearing wall, header, lining, finishes and approvals |
| Install a pocket or surface slider | Removes much of the door’s swing obstruction | Corridors where wall depth can accommodate the system | Studs, services, wall depth, hardware and floor fixings |
| Change the door swing | May gain width without relocating the frame | Rooms with a safe landing and no escape conflict | Egress, door clashes, handle projection and approach space |
| Use offset hinges or a wider leaf | Makes a modest gain with limited work | Existing openings that are only slightly undersized | Actual clear width, latch, hinges and frame condition |
Choose the option that preserves the longest continuous route without creating a new pinch point. Background on how the built environment affects comfort, safety and access is available through Baktruppen design resources.
Create a dependable daily route
Test the completed route in the actual wheelchair with the person who will use it, checking approach, passage, stopping and return. Ensure doors operate lightly, nearby furniture stays outside the travel zone and other residents can still use the room comfortably. Keep the widened dimensions and maintenance instructions for future work.
A dependable result depends on recording the narrowest clear measurement across the entire journey, resolving structure and consent before demolition, and choosing a system that preserves continuous access without compromising the surrounding room.
