Free wheelchair-accessible CAD block pack for AutoCAD

What's in the accessibility pack

The set covers the core accessibility checks. People: a seated wheelchair user in plan and a standing assistant figure for transfer space. Clearance templates: a turning-circle template, a T-shaped turning-space template and a clear-floor rectangle for a forward or side approach. Sanitary: accessible WC layouts with grab rails, an accessible basin with knee clearance, and a level-access shower zone. Furniture and access: roll-under desks and lowered worktop sections, plus ramp-run and door-swing clearance symbols.

These are diagrammatic by design — the turning circle and clear-floor rectangle are meant to be laid over your layout to test it, then frozen or removed before the final plot. Keeping them as their own blocks means you can toggle the whole accessibility overlay on and off.

Typical accessibility dimensions to design around

Reach for these commonly-cited ranges as a starting point, and always verify against your project's code. A wheelchair turning circle is frequently drawn around 1500 mm diameter, with some standards calling for more. A clear floor space for a single wheelchair is commonly about 750–900 mm wide by 1200–1350 mm deep for a forward approach. Accessible WC compartments are often planned around a 1500 mm × 2200 mm zone to fit the transfer space and grab rails. Roll-under desks and worktops typically need around 700–740 mm clear knee height.

These figures vary by jurisdiction and building type, so treat them as typical planning values rather than fixed requirements. The point of the scaled blocks is to let you test whichever specific clearance your code mandates by overlaying it directly on the drawing.

How to use the set to check a layout

Work clearance-first. Drop the turning-circle template into each space a wheelchair user must turn in — the lobby of an accessible WC, the foot of a bed, a kitchen work zone — and confirm nothing intrudes on it. Where a turn isn't needed, use the clear-floor rectangle at each fixture, appliance or desk to confirm the approach space. Place the wheelchair figure at desks and counters with a roll-under block to verify knee clearance.

For the WC, insert the accessible compartment block, align the grab rails to the WC and basin, and check the transfer space stays clear of the door swing. Add the door-swing and ramp clearance symbols where access routes pass through. Keep all these templates on a dedicated accessibility layer so you can overlay them to test, demonstrate them to a reviewer, then freeze them for a clean construction plot.

Plan-view focus and why

Accessibility checking is almost entirely a plan-view exercise — clearances, turning spaces and approach zones are all measured on the floor plane — so this pack is plan-led. The wheelchair figure, turning circles and clear-floor rectangles are all plan blocks meant to be arrayed and overlaid on your floor plan.

Where the pack includes fixtures like the accessible WC and basin, those carry the rail heights and knee clearances you need for an elevation, so you can produce the accessible-bathroom elevation that reviewers often ask for. But the primary work — and the primary value of the pack — is on the plan, testing that a wheelchair user can actually reach and use every space.

Per-item notes

- Wheelchair figure: place it at the point of use (desk, basin, counter) to test the real reach, not just in open floor. - Turning circle: overlay it wherever a 360° turn is needed; if furniture or fixtures clip it, the space fails. - Clear-floor rectangle: use it for forward or side approaches where a full turn isn't required. - Accessible WC layout: keep the transfer space clear of the inward door swing — swap to an outward-opening door if it clips. - Roll-under desk: pair it with the wheelchair figure to confirm knee clearance, not just width. - Ramp clearance symbol: a planning aid for the run and landings — confirm the gradient against your code separately.

Where the accessibility pack is used

Accessibility blocks belong in almost every building type: accessible and adaptable housing, offices and workplaces, schools and universities, clinics and hospitals, shops, restaurants, hotels and all public and civic buildings. Combine them with the people, furniture and kitchen categories so the accessible figures and clearances sit alongside the rest of your layout.

Because they are free and licence-clear, they suit access statements, design-review submissions, student briefs and concept plans where you need to show inclusive design without licensing fuss. Used early, the overlay catches access problems while they are cheap to fix on the drawing rather than expensive to fix on site.
