Designing an Accessible Conservatory: Thresholds, Doors and Circulation
In this guide
Accessible design begins with the intended users and their equipment. A checklist can improve the brief, but it cannot certify accessibility: gradients, thresholds, door forces, controls, drainage and turning space must work together.
Capture actual use
| Area | Information to record |
|---|---|
| Approach | Surface, gradient, width and weather exposure |
| Threshold | Level change, drainage and weather seal |
| Doors | Clear opening, handles, force and transfer space |
| Circulation | Mobility-aid dimensions and turning needs |
| Controls | Reach, visibility and ease of operation |
| Furniture | Routes when chairs and tables are occupied |
Use current local accessibility guidance and involve the intended user. An occupational therapist or access consultant can help where needs are complex.
FAQs
Can a low threshold still manage rainwater effectively?
It can with coordinated external levels, drainage and a tested door detail. Lowering one element without redesign can introduce water risk.
What mobility equipment dimensions should be included in the brief?
Measure the equipment actually used or expected, including turning, footplates, handles and assistance space; generic icons are not enough.
Suggested component
A user-specific access brief with metric/imperial inputs and explicit “not certification” output.
