Can a Garden Annex Be Designed for Wheelchair Access?
Can a garden annex be wheelchair accessible? Yes. We have completed a number of accessible annex projects across Sussex and the South East, designing them from the outset to suit wheelchair users and people with reduced mobility. Features such as wider doorways, wet rooms and step-free access can all be incorporated as part of the initial design.
What door width do you use for wheelchair access? We use an 850mm door width as standard throughout our annexes, providing comfortable access for wheelchair users without requiring an upgrade or bespoke specification.
Do you build ramps and access paths as part of the project? Yes. Paths and ramps are installed by our own team as part of the build programme, typically once the annex itself has been completed.
For many families, accessibility is not something to think about later. It is often the reason they start considering a garden annex in the first place.
Whether the aim is to create comfortable accommodation for an elderly parent, support a family member with a disability or plan ahead for changing mobility needs, good accessibility starts with thoughtful design. We have completed a number of accessible and wheelchair-friendly annex projects across Sussex and the South East, and we design for these requirements from the outset rather than trying to adapt a standard layout afterwards.
Designing for Wheelchair Accessibility From the Outset
Accessibility works best when it is considered during the earliest design stages.
Decisions about room sizes, circulation space, bathroom layouts and external access all influence how easy an annex will be to use day to day. Retrofitting accessibility features later can be more restrictive and often leads to compromises that could have been avoided with early planning.
One example is our standard door specification. We use 850mm wide door openings throughout our annexes, which provides comfortable access for wheelchair users and those using walking aids. This is part of our standard approach and not treated as a specialist upgrade.
Planning accessibility from the beginning also allows us to create layouts that feel spacious and practical rather than clinical. Many families tell us they want accommodation that supports independence while still feeling like a welcoming home, and that is exactly what we aim to achieve.
If you are still exploring different sizes and configurations, our annex range includes layouts that can be tailored around individual mobility requirements.
External Access: Paths, Ramps and Step-Free Thresholds
Getting into, out of and around the property easily is one of the most important aspects of an accessible annex, and it spans both the building itself and the route leading to it.
Where possible, we design our annexes with a level, step-free threshold between the outside path and the entrance door. This reduces trip hazards and removes the need to navigate steps or raised thresholds when using a wheelchair or mobility scooter.
Ground conditions do not necessarily prevent this from being achieved. We use ground screw foundations as standard, and these can extend up to two metres in length. That allows the foundation system to accommodate uneven or sloping gardens while still creating a level finished floor height and step-free entrance. We cover the foundation system in more detail in our guide to what groundworks and foundations are involved in building a garden annex.
The route from the main house matters just as much as the threshold itself, which is why path and ramp installation forms part of our own scope of works rather than being left for homeowners to organise separately. Our team typically completes this once the annex installation has finished, ensuring the final route aligns neatly with the entrance and surrounding landscaping. We consider several practical factors at this stage, including the surface material underfoot, ramp gradients, path widths, drainage and external lighting for safe use during darker evenings.
Every garden is different, so these details are assessed as part of the site visit and overall design process, with the aim of creating access that feels natural and integrated into the garden rather than something added as an afterthought.
Wheelchair Accessible Bathroom Design
Bathrooms are often one of the biggest concerns for families planning accommodation for someone with mobility needs.
The good news is that wet rooms are offered as standard within our annexes and are a common feature in many of the accessible projects we have completed.
A wet room layout removes the need for a shower tray or raised step, making it easier for wheelchair users and those with limited mobility to move safely around the space.
Depending on individual requirements, we can also incorporate grab rails in suitable locations, fold-down or fixed shower seating, clear turning circles for wheelchair manoeuvrability, wash basins positioned at an appropriate height, easy-to-reach storage solutions and lever-style taps for easier operation.
Because bathrooms need reliable water and drainage connections, we coordinate these services as part of the overall build programme. Our guide on how electricity, water and drainage connect to a garden annex explains how this works in more detail.
Doorways and Wheelchair Circulation Space
Accessible design is not only about getting into the annex. It is equally important to be able to move around comfortably once inside.
Using 850mm door widths as standard creates a more generous feel throughout the building and allows wheelchair users to pass easily between rooms.
Open plan layouts are particularly popular for accessible annexes because they reduce the number of internal barriers and make everyday activities simpler. Combining the kitchen, dining and living areas into one connected space can improve circulation and make it easier for family members or carers to provide support when needed.
Kitchen layouts can also be adapted for reduced mobility, with careful consideration given to worktop heights, appliance positioning and the amount of clear floor space available.
The intention is never to create a space that looks overtly adapted. Instead, we focus on designing annexes that are attractive, practical and comfortable for everyone who uses them.
Accessibility and Planning
Adding accessibility features to a garden annex does not normally alter its planning position.
Whether an annex includes wider doorways, a wet room, ramps or step-free access, planning considerations generally remain focused on how the annex is used and whether it is ancillary to the main dwelling.
We manage planning applications where required through our £1,500 planning package, helping homeowners across Sussex, Surrey, Kent and Hampshire navigate the process with confidence. If planning is still one of your main questions, our guide to planning permission for garden annexes explains the position in more detail.
Frequently Asked Questions
Can a garden annex be made fully wheelchair accessible?
Yes. We have completed a number of wheelchair-friendly annex projects and can design layouts around specific mobility requirements, including step-free access, wider doorways, wet rooms and adapted kitchens.
What door width do you use for wheelchair access?
We use 850mm door widths as standard throughout our annexes, providing comfortable access for wheelchair users without requiring any additional upgrade.
Can a garden annex include a wet room?
Yes. Wet rooms are offered as standard within our annexes and are a common choice for accessible layouts.
Can ground screws accommodate uneven or sloping gardens?
Yes. Our ground screw system can use screws up to two metres long, allowing uneven ground levels to be accommodated while maintaining a level threshold at the entrance.
Do you build access paths and ramps as part of the project?
Yes. Our own team designs and installs paths and ramps as part of the build programme, usually after the annex has been completed.
Does accessibility affect planning permission for a garden annex?
No. Accessibility features do not usually change the planning position of an annex. The key consideration remains whether it functions as accommodation ancillary to the main home.

Conclusion
For many families, an accessible annex provides reassurance that a loved one can remain close by while enjoying a greater level of independence and comfort.
Drawing on real project experience across Sussex and the South East, we understand that good design goes beyond simply meeting dimensions on a drawing. It is about creating spaces that work naturally for the people who will use them every day.
