Designing for change, not just for now

A home that works perfectly today may not work so well in ten or twenty years. Children grow, knees ache, eyesight changes, and a sprained ankle or a broken hip can turn a familiar staircase into a daily obstacle. Accessible design is not about creating a clinical or institutional space. It is simply good, thoughtful architecture: generous, calm and practical, with room for everyone from toddlers to grandparents. Whether you are renovating a Victorian terrace or planning a new build, thinking about accessibility early usually costs less than retrofitting later, and the result is a home that feels comfortable rather than medical.

Level access: the first and most important step

Steps at the front door are one of the most common barriers to independent living. Aim for a level or gently sloping approach, ideally with a maximum gradient of 1:12 (and 1:15 where space allows). Even a single 100mm step can stop a wheelchair, a walking frame or a delivery trolley. Where a ramp is unavoidable, include a level landing at the top and bottom, and handrails on both sides.

• Thresholds: keep external door thresholds to 15mm or less, ideally with a chamfered edge.
• Paths: firm, slip-resistant surfaces at least 1200mm wide, with no loose gravel.
• Lighting: motion-sensor lights at the entrance reduce fumbling for keys in the dark.
• Shelter: a canopy or recessed porch gives you time to unlock the door in the rain.

Inside, a level ground floor with a accessible WC or shower room is a huge advantage. If your home is on a slope, consider a through-floor lift or a ground-floor bedroom extension rather than relying on stairs alone.

Doorways, corridors and turning circles

Narrow doorways are a frequent frustration. A clear opening width of 850mm is a good minimum for a wheelchair or a walking frame; 900mm is better if you have the space. Remember that the door leaf itself, the frame and the architrave all eat into that width. A 762mm door (common in older UK homes) gives you only around 700mm clear, which is tight for many users.

Corridors should be at least 1200mm wide, and 1500mm where you need to turn a wheelchair or pass someone. At the end of a corridor or in front of a key door, allow a 1500mm turning circle. Sliding or pocket doors save swing space and are easier to operate with limited reach. Lever handles are far easier than round knobs, and they can be operated with a closed fist or an elbow.

• Consider future needs: a 900mm door frame now may allow you to widen the opening later without moving walls.
• Visual contrast: door frames and handles in a contrasting colour help people with low vision.

Bathrooms that adapt with you

The bathroom is where accessibility matters most, and where retrofitting is most disruptive. If you are renovating, install a ground-floor shower room or WC even if you do not need it yet. A level-access wet room with a gentle slope to a linear drain removes the step over a tray. Reinforce the walls around the WC, shower and bath with plywood or blocking so that grab rails can be added later without major works.

Choose a wall-mounted WC at a comfortable height (around 480mm to the seat) with space either side for a carer or a wheelchair. A wheel-under washbasin with lever taps and a shallow bowl allows someone to sit while washing. Non-slip floor tiles, a fold-down shower seat and a thermostatic mixer tap that limits the maximum temperature are simple, affordable additions. If you have the space, a 1500mm x 1500mm shower area gives room for a carer to assist.

Kitchens and living spaces that work for everyone

An accessible kitchen is not about lowering everything. It is about variety and flexibility. Include a mix of worktop heights: 900mm for standing, 750mm for seated use, and a section with clear knee space under the sink and hob. Pull-out baskets, drawer-style fridges and side-opening ovens are easier to reach than low cupboards. Lever taps and a shallow sink reduce strain.

In living areas, leave clear routes between furniture. A 1000mm gap between a sofa and a coffee table allows a walking frame to pass. Avoid deep-pile carpets, which are hard to push a wheelchair over; low-pile or hard flooring with a matte finish is safer. Consider a ground-floor bedroom or a room that could easily become one, with a wardrobe that has hanging rails at two heights.

Future-proofing: structure, services and storage

Good accessibility is often invisible. During a renovation, add extra blocking in walls for future grab rails, widen stud walls to 150mm so they can take a hoist, and run capped-off pipes and cables for a future shower or lift. Underfloor heating frees up wall space and avoids radiators that block circulation. Smart lighting with motion sensors and dimmable LEDs helps everyone, especially at night.

Storage should be reachable: avoid deep cupboards that require bending or stretching. A well-placed shelf at 1200mm is easy for most people. Finally, think about the outside: a gentle path to the bin store, a raised planting bed, and a tap at waist height all support independent living. Accessible design is not a compromise on style. It is a quiet, generous way of making a home that looks after you, whatever the years bring.
