Balham homeowners want garden buildings that feel like a true extension of the house, not an afterthought. Whether you’re near Balham station or closer to Tooting Bec Common, we create garden offices, summer houses and garden rooms that work year-round. Expect clean lines, solid insulation and a finish that complements your existing property. We can also add practical storage with sheds and workshops that don’t dominate the garden.
The Balham mix of Victorian terraces, Edwardian houses and mansion conversions often comes with narrow side access and carefully planned rear gardens. Our team designs around these constraints, using modular builds where needed and keeping disruption controlled. In areas such as Nightingale and Clapham South, clients often ask for quiet workspaces for hybrid working, plus discreet storage for bikes and prams. We tailor layouts, glazing and door positions to suit how you actually move through the garden.
From the first site visit, we check levels, drainage, boundaries and access before recommending foundations and a build method. You’ll receive a clear specification covering structure, insulation, electrics readiness and finishes, so there are no surprises. We keep neighbours in mind with considerate scheduling and tidy working practices. Local homeowners choose us for reliable project management, high-end workmanship and a 10-year warranty on our builds.
Working across the London Borough of Wandsworth, we’re used to SW12 access limits, parking controls and neighbour-sensitive builds. Gardens around Balham High Road often have mixed ground and legacy paving, so we assess sub-bases and drainage before setting foundations. We plan deliveries to reduce disruption and keep pathways protected. The result is a smoother build and a better long-term finish.

Costs vary by size, insulation and finishes. As a guide, a quality shed or small workshop often starts around £2,500–£6,000. Insulated garden offices and garden rooms typically fall between £12,000–£35,000+, depending on glazing, electrics, heating and cladding. Larger log cabins, bespoke pergolas or gazebos can range from £4,000–£25,000+. We provide a detailed, itemised quote after a site visit.
Most projects take 2–6 weeks from start on site, depending on complexity. A simple shed base and install can be completed in a few days, while insulated garden rooms with electrics, plasterboard and premium finishes take longer. Timescales are affected by access (common with terraces), groundwork needs, bespoke joinery, and weather during foundations and roofing. We confirm a realistic programme before work begins.
Many garden buildings can be installed under permitted development, especially if they’re within height limits and used as incidental accommodation (not a separate dwelling). However, rules can change based on proximity to boundaries, listed buildings, conservation considerations and previous extensions. We’ll talk through your intended use, check constraints relevant to the London Borough of Wandsworth, and advise whether a planning application or building regs input is sensible before you commit.
We provide a 10-year warranty covering workmanship and structural integrity for the garden building we construct, subject to normal use and maintenance. This includes key elements such as framing, fixings and weatherproofing details. Manufacturer warranties apply separately to products like doors, windows, membranes and cladding systems. We also supply care guidance so timber finishes, seals and gutters perform as intended over the long term.
You can choose from contemporary garden rooms, traditional summer houses, robust workshops, log cabins, gazebos and pergolas. Popular options include composite or timber cladding, EPDM or felt roofing, aluminium or timber doors, and double or triple glazing for offices. Internally, we can prepare for electrics, data and heating, plus storage solutions. We help you balance style, durability and budget to suit your Balham garden and property.
