Eastfields homeowners are using garden offices to gain space for work, study and creative projects. Whether you’re near Eastfields station or walking distance to Figges Marsh, we can create a warm, secure room that works in every season. Our builds include insulation, electrics, heating and internet-ready cabling as standard. The result is a dedicated workspace that feels like a real extension of your home.
The Eastfields area has a mix of Victorian terraces, 1930s semis and newer developments, each with different garden sizes and access routes. We tailor foundations and layouts to suit long, narrow plots and shared side passages common around SW16 and CR4. For modern homes, we can match clean lines and contemporary finishes. For period properties, we design garden rooms that sit comfortably with existing brickwork and boundary details.
From the first site visit to final handover, we manage the full process: survey, design, foundations, build, electrics and finishing. You’ll get clear specifications, realistic timescales and tidy working practices that respect neighbours and access. We also provide planning advice and handle the details that often cause delays, such as cable routes and drainage falls. With our nearby base just five minutes away, support is always close if you need us.
Across the London Borough of Merton, gardens can vary from firm ground to softer, made-up areas linked to older landscaping. We assess levels, drainage and soil conditions to choose the right foundations and prevent movement. Access and parking can be tight around Mitcham and Pollards Hill, so we plan deliveries and waste removal to minimise disruption. We also factor in boundary lines, overlooking and height limits when advising on placement.

Costs vary by size, specification and groundworks. As a guide, smaller insulated garden offices often start from around £12,000–£18,000, while mid-size bespoke builds with higher-end finishes, heating and upgraded glazing typically fall in the £18,000–£30,000 range. Larger designs with extensive sound proofing, premium cladding, extra electrics or complex foundations can exceed £30,000. We provide a detailed itemised quote after a site survey.
Most garden office projects take around 2–6 weeks from start on site, depending on the design and specification. Simple builds with straightforward access and standard foundations can be completed faster, while bespoke layouts, heavier groundworks, or upgraded electrics and sound proofing add time. Lead times for doors, glazing and cladding can also affect schedules. We confirm a clear programme before work begins and keep you updated throughout.
Many garden offices can be built under permitted development, provided they meet limits on height, placement and overall use (for example, incidental use rather than a separate dwelling). However, rules can change if you’re in a restricted area, near boundaries, or if previous extensions have used up allowances. We give planning advice, check the key criteria, and can recommend a lawful development certificate where it adds reassurance.
We provide a 10-year warranty covering the main structure and build quality of your garden office, including issues linked to workmanship and installation. Manufacturer warranties apply separately to items such as doors, windows, cladding systems, heaters and electrical components. We also document the specification and maintenance guidance so you know how to keep finishes performing well. If anything needs attention, our local team can respond quickly.
We offer bespoke designs with a wide choice of finishes, including composite cladding, timber cladding, and modern render-style boards. Inside, popular options include plastered walls, acoustic panels for sound control, and durable flooring such as LVT. You can choose double or triple glazing, integrated blinds, rooflights, and different heating types. We help you balance aesthetics, insulation performance and budget, then finalise a design that suits your garden and home.
