Compact yet spacious garden annexe

An L-shaped annexe on a 6m x 8.5m footprint, designed with its client so that everything needed for accessible living is there without announcing itself.

Garden annexe design for young person to live independently
Annexe Spaces  6m x 8.5m, L-shaped

This L-shaped annexe has created a compact yet spacious, accessible home for a young man. Annexe Spaces worked closely with their client to design a tailored, stylish apartment in the garden.

As someone living with a disability, I am impressed by the thoughtful design that Annexe Spaces and their client have achieved together. The essential elements for accessible living are integrated so cleverly and discreetly that you hardly notice them. This is one of the most remarkable garden annexes we have seen.

The annexe occupies a 6m x 8.5m footprint. The choice of an L-shaped layout draws the view towards the heart of the garden. The two wings are connected by a decked area, with French doors and bifold doors that open onto the decking, allowing the living space to extend seamlessly into the garden.

The deck  level with the floor inside

Annexe Spaces installed a low-maintenance composite decking system in a contemporary dark grey finish, complementing the powder-coated aluminium doors, window frames, and roof kerbs.

In their designs, Annexe Spaces ensure that the decking is level with the internal floor and fit doors with low threshold systems, eliminating steps between outdoor and indoor spaces. This thoughtful feature makes the annexe more accessible for wheelchair users and reduces the risk of trips or falls.

At a glance

  • Size: a 6m x 8.5m footprint, in an L whose two wings are joined by a deck and turn the view towards the middle of the garden.
  • Accessibility: the essentials are built in so discreetly you barely notice them — decking level with the internal floor, low-threshold doors, and a 2m x 2.1m shower room that is fully wheelchair accessible.
  • Zoning: the corner of an L is usually wasted; here it has been given a job, and the living area runs open-plan with a curtain rather than a door closing off the double bedroom.
  • Room for rehab: there is space for a home gym, so the owner can keep up his rehabilitation at home.
  • Outside: low-maintenance composite decking in dark grey, matched to powder-coated aluminium doors, window frames and roof kerbs.

Zoning

L-shaped annexe with smart zoning

We have featured many L-shaped garden rooms over the years, but what makes this one unique is how Annexe Spaces and their client have zoned the interior for different uses. The corner of an L-shaped building is often wasted space, but here, the shower room has been positioned in the corner, making the best use of the area.

The corner  given a job rather than wasted

This is one of the most beautifully designed shower rooms ever fitted in a garden annexe. The 2m x 2.1m room is elegantly detailed and fully wheelchair accessible. Annexe Spaces manage the installation of the shower room fittings and connections to mains services as part of their comprehensive service-something many companies leave you to organise separately.

The main living area is open plan, with a curtain separating the double bedroom to provide privacy from the day-to-day living space. The absence of doors makes the annexe feel larger, with each area flowing into the next.

There is even space for a home gym, allowing the owner to continue with his rehabilitation. This project is a fine example of what can be achieved by working with an experienced bespoke garden annexe designer like Annexe Spaces.
