If you’re near Hither Green station or walking distance to Mountsfield Park, a garden annexe can transform unused outdoor space into a practical extra room. Fine Landscaping creates self-contained annexes with a bedroom area, bathroom and kitchenette, ready for everyday living. We handle insulation, electrics and plumbing as part of a coordinated build. The result is a warm, private space that works year-round in SE13.
Hither Green’s Victorian terraces, Edwardian houses and 1930s semis often have generous gardens but limited internal layout flexibility. We plan annex footprints that respect neighbouring boundaries and make the most of long, narrow plots common around Lee and Grove Park. Our designs suit period homes, with finishes that complement brickwork, sash windows and established planting. You get modern comfort without compromising the character of your property.
From the first site visit to final handover, we keep the project clear and organised: measured survey, concept drawings, specification, and a fixed-scope schedule. We coordinate qualified trades for electrics and plumbing, and we provide planning support where required. Homeowners choose us for tidy working practices, reliable communication and consistent build quality. We’re only around 25 minutes away, so aftercare is prompt and practical.
Across the London Borough of Lewisham, gardens can have mixed ground conditions and mature tree roots, especially near Manor Park and Hither Green Cemetery. We assess levels, drainage routes and service runs early, so foundations and plumbing are planned properly. Access can be tight on Victorian streets, so we organise deliveries, protect paths and keep sites secure. We also factor in parking and council expectations to keep the build moving.
Rated 4.9/5 from over 280 verified reviews
Costs vary with size, specification and how “turnkey” you want it. In the SE13 area, a compact, well-insulated annexe with electrics and basic finishes often starts around £45,000–£70,000. A larger self-contained build with kitchenette, bathroom, upgraded glazing, heating and higher-end interiors is commonly £80,000–£140,000+. Site access, groundworks and service connections can shift budgets either way.
A typical build takes around 8–14 weeks on site once designs and specifications are agreed. Simpler, smaller annexes can be quicker, while larger layouts with a full bathroom, kitchenette, bespoke joinery and complex plumbing runs may take 14–20 weeks. Timescales are influenced by groundworks, access for materials, lead times for windows/doors, and whether planning approval or party wall matters are required.
Some garden buildings can fall under permitted development, but a self-contained annexe intended for independent living can trigger additional rules. In Lewisham, factors such as overall height, proximity to boundaries, use as a separate dwelling, and conservation constraints can affect what’s allowed. We provide planning support, check your property’s status, and advise whether a lawful development certificate or full application is the safest route before work begins.
We back our workmanship with a 10-year warranty covering structural build quality and installation standards for the annexe shell, including insulation, cladding/roofing integrity and weatherproofing when installed by our team. Manufacturer warranties apply to products such as windows, doors, membranes and heating components. We also complete a clear handover with care guidance, so you know how to maintain finishes and keep everything performing as intended.
We tailor the look to your home and garden, from contemporary composite cladding to timber, render finishes or brick slips that suit Victorian and Edwardian properties. Inside, you can choose layouts with a separate shower room, compact kitchenette, built-in storage and acoustic upgrades for office use. Heating options include electric panel, underfloor systems or air-to-air solutions. We guide you through samples, durability and maintenance so choices fit your budget and lifestyle.
