Professional Outbuildings & Garden Rooms for Bath Properties

The demand for high-quality outbuildings and garden rooms has grown enormously, and Brick Builds constructs them to the same standard as any other building project — with proper foundations, structural walls, insulation, electrical supply and high-specification finishes. Whether you need a home office in the garden, a gym or studio, a detached garage or a fully insulated annexe for a family member in Bath, we design and build it to last.

Our outbuildings in Somerset are built in brick, stone or timber frame depending on your preference and planning requirements. Unlike many garden room suppliers who install flat-pack structures with minimal foundations, everything we build in Bath is constructed properly from the ground up — with correct drainage, weatherproofing, insulation to Part L standards and electrical installation by certified contractors. The result is a building that adds real, lasting value to your Somerset property.

An outbuilding or garden room can be constructed under Permitted Development in most Somerset properties, provided it meets the relevant size, height and use restrictions. We advise on this as part of our initial consultation and handle the full build process in Bath from groundworks through to decoration — including plumbing and electrics coordination. We also carry out larger detached annexe builds that require full planning permission across Somerset.

Frequently Asked Questions �� Outbuildings & Garden Rooms in Bath

Do I need planning permission for an outbuilding in Bath?
Many outbuildings in Bath qualify under Permitted Development, meaning no planning permission is required provided they meet size, height and use criteria. Conservation areas and listed properties in Somerset have stricter rules. We advise on this for free during our initial visit and have extensive experience navigating Somerset planning requirements.
What is the difference between a garden room and an annexe?
A garden room is typically a single-use space without full domestic facilities — a home office, gym or studio. An annexe includes a kitchen, bathroom and sleeping area and constitutes a separate dwelling. Annexes in Somerset require planning permission and must meet building regulations as a habitable space. We build both to the same high standard.
How much does a garden room cost in Somerset?
A properly built, insulated garden room or home office in Bath typically costs £15,000–£35,000 depending on size, materials and specification. This includes foundations, structure, insulation, electrical installation and internal finishes. Call 01460 353121 for a free, no-obligation site visit.
Can you build an oak frame outbuilding in Somerset?
Yes — we construct oak frame and heavy timber outbuildings across Somerset. Oak frame buildings are particularly well suited to traditional Somerset rural settings and can be built as garages, cart lodges, garden rooms or annexes. We work with specialist oak frame suppliers and provide a complete turnkey build including groundworks.
