If you want a garden office, summer house or workshop that feels like a real extension of your home, we build it properly from the ground up. Our team works across CR4, including projects near Mitcham Common and Mitcham Junction station. Every build is planned around how you’ll use the space—quiet working, entertaining, storage or hobbies. Expect clean lines, solid foundations and finishes that suit your garden.
Mitcham’s mix of Victorian cottages, 1930s semis and modern estates means no two gardens (or access routes) are the same. We regularly design buildings that fit narrower side passages, long plots and family gardens that need to stay usable during the works. For homes around Pollards Hill and Figges Marsh, we often create multi-purpose rooms that double as storage and a comfortable retreat. We’ll match proportions, rooflines and cladding choices to complement your property.
We start with a site survey, discuss intended use, then provide clear options for base type, insulation, electrics and finishes. Your build is scheduled with tidy working practices, careful material handling and a dedicated point of contact. We use proven construction methods and quality timbers to minimise movement and weathering over time. Local homeowners choose us for reliable timelines, transparent specifications and workmanship backed by a long warranty.
We’re used to the practicalities of working in the London Borough of Merton, including parking constraints and shared access on residential streets. Ground conditions can vary near open land such as Mitcham Common, so we recommend base types that suit drainage and long-term stability. For 1930s semis and Victorian cottages, we plan deliveries and construction to protect existing paths, lawns and boundaries. We also factor in neighbour considerations and site set-up to keep disruption down.

Costs depend on size, specification and whether you need insulation, electrics and heating. As a guide, a quality shed or storage building often starts from around £1,500–£4,000. Insulated garden offices and garden rooms typically range from £10,000–£30,000+, while larger log cabins, workshops or bespoke builds can be £20,000–£60,000+. We’ll survey your CR4 garden and provide a detailed, itemised quote.
Many smaller structures such as sheds, pergolas and gazebos can be installed in 1–3 days once materials are ready. Insulated garden rooms and offices usually take 2–6 weeks from start on site, depending on groundwork, electrics, internal finishes and weather. Timescales also change with access constraints, bespoke joinery and lead times for doors, glazing or specialist cladding. We confirm a realistic programme before work begins.
Many garden buildings fall under permitted development, especially if they’re within height limits, positioned correctly and used as ancillary space (not a separate dwelling). However, rules can change for listed buildings, flats, corner plots, or if you’re close to boundaries and outbuildings cover a large portion of the garden. We’ll check the key criteria for your Mitcham property and advise if a lawful development certificate or planning application is sensible.
We provide a 10-year warranty on our workmanship for garden buildings we construct, covering structural integrity and installation-related issues. This includes key elements such as the base, framing, fixings and weatherproofing details when maintained as advised. Manufacturer warranties on products (for example, membranes, doors, glazing or cladding treatments) are passed on where applicable. We also offer practical aftercare guidance to keep your building performing well year-round.
You can choose from modern garden rooms with composite or timber cladding, traditional summer houses, robust workshops, log cabins, and open structures like pergolas and gazebos. Popular options include cedar or larch cladding, EPDM or felt roofing, aluminium or uPVC glazing, and insulated walls and floors for year-round use. We help you balance looks, maintenance and budget, then tailor dimensions, doors and windows to your garden layout and privacy needs.
