Garden Rooms & Outbuildings in London

💻 Garden Offices & Studios

Working from home is here to stay, and a dedicated garden office gives you a proper workspace separate from the house. Our garden offices are fully insulated, double glazed, and wired for power and data. They're designed as year-round workspaces, not glorified sheds.

Standard sizes range from 3m × 2.5m (a comfortable single-person office) to 5m × 4m (suitable for two desks or a desk plus meeting area). We also build bespoke sizes to fit your garden layout and can incorporate features like built-in storage, cable management, and external lighting.

🏠 Custom Outbuildings

Beyond offices, we build garden rooms for a range of uses — home gyms, art studios, music rooms, guest accommodation, and general purpose entertaining spaces. The construction is the same regardless of use: concrete pad or screw pile foundations, treated timber frame, insulation, vapour barrier, and quality cladding.

Cladding options include timber (cedar, larch, or treated softwood), composite panels, and rendered finishes. Roofing is typically EPDM rubber membrane with a slight pitch for water runoff. We finish the interior to your specification — from basic plywood lining to fully plastered and painted walls.

💷 How much does a garden room cost?

A basic insulated garden room of around 3m × 3m typically costs between £10,000 and £15,000 including foundations, electrics, and finishing. Larger rooms (4m × 5m or above) with premium cladding and full interior finishing range from £15,000 to £30,000.

The main cost variables are size, cladding material, interior finish, and electrical requirements. We provide a fully itemised quote so you can adjust the specification to fit your budget. We also offer a shell-only option if you want to handle the interior fit-out yourself.
