Garden room drawings
Fixed-price drawings for garden offices, studios, gyms, annexes and outbuildings. Most garden rooms qualify under permitted development — no full planning application required. We tell you whether yours does, then draw it the right way.
Every type of garden room
Garden rooms are one of our most-asked-for projects — and for good reason. They add genuinely useful space, often without the cost or disruption of an extension. Pick the closest match to what you have in mind:
A purpose-built workspace at the bottom of the garden. Typically 12–20m². Includes power, lighting, broadband, sometimes mini-split air-con. Almost always permitted-development. Add-on: a small WC and tea-point.
Dedicated space for weights, yoga, Pilates, dance. We design with the right floor build-up to take impact loads, plus considered ceiling height (2.5m+) and rubber flooring detail in the construction spec.
A self-contained one-bedroom unit with kitchenette and shower room. Used for ageing parents, returning kids, Airbnb. Falls outside permitted development if it's a separate dwelling — needs full planning permission.
Multi-purpose spaces — art studio, music room, reading nook, pool house. Generally permitted-development if under 30m² and meeting height/proximity rules. We design to maximise the natural light.
What you get
Garden rooms are usually built by specialist garden-room companies, generalist builders, or DIY enthusiasts. We tailor the drawings & spec to whoever's on the spanner, with enough detail that the council signs off and the build doesn't drift.

For most UK homeowners, the answer is no. Garden rooms are usually classed as "outbuildings" under Class E permitted development, which lets you build them without full planning permission — provided you stay within the rules.
To qualify under permitted development, your garden room must be:
· Single storey with a maximum eaves height of 2.5m
· Maximum overall height of 4m (dual pitch) or 3m (any other roof)
· Within 2m of a boundary: maximum height 2.5m
· Used incidentally to the main house — i.e. not as a separate dwelling, not lived in
· Not in front of the principal elevation
· Not covering more than 50% of the garden's land area
You'll need full planning permission if you're in a conservation area, the property is listed, you exceed the size limits above, or you intend the room to be lived in as a separate dwelling (an annexe with a bedroom, kitchen and shower would normally fail this test).
Even if you don't need planning permission, you may still need Building Regulations approval. The trigger is usage and electrical work: any garden room with a hardwired electrical supply, or any room over 30m² internal floor area, falls within Part P. We sort this on your behalf.
