A well-built summer house adds usable space without changing the feel of your garden. In Carshalton, we design and build garden rooms that suit everything from relaxed seating to a home office or studio. We regularly work near Carshalton Ponds and around SM5, so we understand the local mix of plot sizes and access. Every build is tailored, from foundations through to interior finishing.
Homes across Carshalton Beeches, Hackbridge and Wallington range from Victorian and Edwardian houses to 1930s semis and other period properties. That variety calls for designs that complement existing brickwork, rooflines and garden layouts. We can match traditional styles with timber detailing, or deliver contemporary designs with clean lines and modern glazing. Insulation options are available to keep the space comfortable beyond summer.
We start with a site visit, clear measurements and a practical design proposal, then confirm foundations, drainage considerations and cable routes before work begins. Our team handles electrics, insulation and internal lining so the finished space feels like a proper room, not a shed. You’ll get straightforward planning advice, tidy working practices and a build schedule you can rely on. Local homeowners choose us for consistent workmanship and a 10-year warranty for peace of mind.
Across the London Borough of Sutton, gardens can vary from compact plots to long, established lawns near parks such as Oaks Park. We plan deliveries and waste removal around local parking and access, keeping disruption low. Ground conditions can differ between older landscaped gardens and newer reworked plots, so we specify the right base and subframe. If you’re in SM5, we’ll also advise on siting to protect privacy and light.

Costs vary by size, specification and whether you want insulation and electrics. As a guide, a small bespoke summer house might start around £3,500–£6,500. Mid-size insulated garden rooms with electrics commonly fall in the £7,000–£15,000 range. Larger, fully finished builds with premium glazing, heating readiness and higher-end cladding can be £15,000–£30,000+. A site visit helps us price accurately.
Most builds take 1–3 weeks from breaking ground to completion, depending on complexity. A simple structure on a prepared base can be quicker, while insulated builds with electrics, plasterboard-style lining and bespoke joinery take longer. Timescales are affected by access, groundwork requirements, drying time for bases, and lead times for doors, windows and cladding. We provide a clear schedule before starting and keep you updated throughout.
Many summer houses fall under permitted development, especially when they’re single-storey, within height limits and used as incidental garden space. However, rules can change if you’re close to boundaries, in a restricted area, or if you want plumbing, sleeping accommodation or a larger footprint. We give planning advice for Carshalton projects and can help you check Sutton Council guidance. If permission is needed, we’ll support you with the details required.
We provide a 10-year warranty covering our workmanship and the structural integrity of the build when maintained as advised. This includes key elements such as the frame, fixings and installation of cladding, roofing and internal finishes. Manufacturer warranties may also apply to windows, doors, membranes and electrical components. We’ll explain what’s covered, how to care for timber finishes, and what to do if you ever need support after completion.
We offer traditional styles with timber boarding, felt or shingle-style roofing, and classic doors and windows, as well as contemporary designs with clean profiles and larger glazing. Popular upgrades include insulated walls and roof, vapour control layers, durable composite cladding, and smart interior finishing such as panelling, shelving and built-in storage. We’ll help you choose a layout, orientation and specification that suits your garden use, budget and the look of your Carshalton home.
