From garden offices for hybrid working to summer houses for weekends, we build outdoor structures that add practical space in Raynes Park. Many clients are a short walk from Raynes Park station and want a quiet, insulated room that feels separate from the house. We also create workshops, sheds, log cabins, gazebos and pergolas tailored to your layout. Every build is planned around how you use your garden, not a one-size kit.
Raynes Park’s family streets include plenty of 1930s semis alongside Victorian terraces and Edwardian houses, often with long rear gardens and side access constraints. We design buildings that complement period brickwork, bay windows and mature planting, while keeping footprints sensible. Whether you’re near Wimbledon, New Malden or Motspur Park, we can match rooflines, cladding tones and glazing to your property style. The result looks intentional, not bolted on.
We start with a site visit, discuss intended use, power needs and insulation, then provide a clear specification and itemised quote. Our team handles base preparation, drainage considerations, electrics coordination and a clean, safe build programme. You’ll get regular updates, considerate working hours and a finish that’s ready to furnish. Homeowners choose us because we’re local (around 20 minutes away), consistent, and we stand behind our work.
Across the London Borough of Merton, access can be tight on terraced streets and driveways, so we plan deliveries, parking and waste removal in advance. Soil conditions vary, and we’ll specify the right base type to prevent movement and water pooling. If you’re near Cannon Hill Common or Prince George's Playing Fields, we’ll also consider tree roots, shade and drainage runs. Our garden building contractors Raynes Park area clients value practical solutions that suit real gardens.

Costs depend on size, insulation, glazing and the base. As a guide, a quality shed or small workshop often starts from £2,000–£6,000. A fully insulated garden office or garden room is commonly £10,000–£30,000+, while larger log cabins can run £15,000–£45,000+. Groundworks, electrics, heating and premium finishes can increase budgets, and we’ll itemise everything clearly.
Most builds take 1–3 weeks on site once materials are ready, depending on size and complexity. A simple shed base and install may be a few days, while insulated garden rooms with electrics, plasterboard and fitted finishes can take longer. Timescales are affected by access, ground conditions, bespoke joinery, glazing lead times and weather. We provide a realistic programme before starting.
Many garden buildings can be installed under permitted development, provided they meet limits on height, location and use (for example, not being used as a separate dwelling). However, rules can change for listed buildings, flats, maisonettes, or if previous permissions removed permitted development rights. We’ll review your plans against current guidance and advise if a lawful development certificate or planning application is sensible before work begins.
We provide a 10-year warranty on our workmanship for the garden building structure and installation, giving you long-term reassurance. This covers issues arising from how the building is constructed and fitted, including fixings and assembly. Manufacturer warranties apply separately to items such as doors, windows, membranes and cladding products where relevant. We’ll explain what’s covered in writing and how to maintain the finish for best longevity.
We build in a range of styles, from contemporary garden rooms with large glazing to traditional summer houses and log cabins. Popular choices include cedar or composite cladding, EPDM or felt roofs, aluminium or uPVC doors, and optional verandas, pergolas or integrated storage. Internally, you can choose insulation levels, plastered walls, lighting layouts and flooring. We’ll help you balance looks, security, maintenance and budget.
