Earlsfield homeowners love practical space that works hard, whether it’s a quiet office, a gym, or a family hang-out. Our garden rooms are built to perform in all seasons, with proper insulation, electrics and heating options. We’re used to working around the pace of SW18 life, close to Earlsfield station and Garratt Lane. The result is a room you’ll genuinely use, not a shed you tolerate.
The Earlsfield area has a strong mix of Victorian terraces, Edwardian houses and smart conversions, often with long, narrow gardens and side-return access. We design around typical boundary lines, mature planting and existing patio levels so the room sits naturally in your garden. Whether you’re near Wandsworth Cemetery or closer to the River Wandle, we tailor foundations and drainage to suit the plot. Every build is planned to maximise internal space while keeping the outside footprint sensible.
From the first survey to the final snagging visit, we run a clear, fixed-scope process with a dedicated project lead. You’ll get detailed drawings, a build schedule, and clear specifications for insulation, glazing and electrics before work starts. Our teams protect access routes, keep the site orderly, and communicate daily so there are no surprises. Local homeowners choose us for dependable timelines, high-end finishes, and workmanship backed by a 10-year warranty.
Across the London Borough of Wandsworth we often encounter tight access, controlled parking and shared boundaries, especially around terraces off Garratt Lane. We plan deliveries, waste removal and working hours to reduce disruption, and we protect paving and hallways during access. Ground conditions can vary near the River Wandle, so we assess levels, drainage and base requirements before confirming the build-up. The design is then adjusted to your plot so the room stays warm, dry and compliant.

Most garden rooms in Earlsfield fall between £10,000 and £40,000 depending on size, specification and access. A typical fully insulated garden office or studio is usually £15,000–£25,000, including electrics, internal lining and quality doors/windows. Costs rise with larger footprints, premium cladding, extensive glazing, bathrooms or bespoke joinery. We provide a detailed breakdown after a site visit in SW18.
A standard build usually takes 2–4 weeks from groundworks to final finishes, assuming good access and no major enabling works. Timescales can extend if you need significant excavation, complex drainage solutions, bespoke glazing, or additional services such as plumbing for a WC. Weather and delivery lead times for specialist materials can also affect the programme. We confirm a realistic schedule before starting and keep you updated throughout.
Many garden rooms can be built under permitted development, but it depends on height, location in the garden, total outbuilding coverage and whether your property has restrictions. Conversions, flats and some homes near designated areas may have tighter rules. We review your site, check the relevant guidance for the London Borough of Wandsworth, and advise if a lawful development certificate or planning application is sensible. We design to meet the rules wherever possible.
We provide a 10-year warranty on workmanship and structural elements of your garden room, giving you confidence long after the build is complete. This covers issues related to installation quality, such as structural integrity, weatherproofing and key construction details. Manufacturer warranties on windows, doors, cladding and electrical components also apply, depending on the products selected. We complete a handover checklist and remain available for aftercare and advice.
You can choose from contemporary or traditional designs, with popular options including composite or timber cladding, aluminium or uPVC glazing, and flat or mono-pitch roofs. Internally, most clients opt for plastered walls, durable flooring and built-in storage for a clean finish. We also design layouts for home offices, studios, summer houses, gyms and entertainment spaces, all fully insulated. We’ll guide you through options that suit your budget, garden size and style of home.
