Knightsbridge homeowners often need discreet, high-spec extra space that suits premium surroundings near Harrods and Hyde Park. Our garden annexes are built as true mini-homes, not glorified sheds—complete with kitchenette, bathroom and bedroom options. Every build is insulated for year-round comfort and finished to complement refined gardens and terraces. We work across SW1 and SW3 with a focus on clean lines, quiet performance and lasting value.
Property layouts here vary from grand mansion blocks with private courtyards to period townhouses in Belgravia and South Kensington with compact, carefully landscaped gardens. Access can be tight, boundaries are sensitive, and neighbours are close—so design and sequencing matter. We tailor foundations, drainage and services to the site, whether it’s a paved mews-style garden or a planted courtyard. If you’re in SW7, we’ll help maximise usable space while keeping the look architectural and understated.
Fine Landscaping manages the full journey: survey, concept design, specifications, and a clear build programme with tidy working practices. Your annex is delivered with certified electrics, properly planned plumbing runs, and insulation that meets modern expectations. We provide planning support and handle the practical details that protect timelines in central London. Homeowners choose us for consistent communication, premium finishes, and a 10-year warranty for peace of mind.
Garden annexes Knightsbridge area projects often involve restricted access, strict delivery windows and controlled parking. We plan logistics around resident requirements and local council expectations in the Royal Borough of Kensington and Chelsea/City of Westminster. Many gardens sit over mixed ground and historic drainage routes, so we survey levels and services before we build. Our detailing suits premium façades and boundary-sensitive plots common around Chelsea and Mayfair.
Rated 4.9/5 from over 280 verified reviews
Costs in Knightsbridge typically start from around £45,000–£70,000 for a compact, well-finished annex shell with electrics. Fully self-contained builds with kitchenette, bathroom, plumbing, higher insulation specs and premium joinery more often fall between £80,000–£160,000+. Pricing depends on size, access constraints, foundation requirements, service connections, and the level of interior fit-out you choose.
A typical programme is 8–14 weeks on site for many annexes, after design is agreed. Allow extra time for design development, structural calculations, and ordering bespoke glazing or joinery. Tight access in SW1/SW3, neighbour considerations, and complex plumbing routes can extend timelines. If planning approval is needed, add the council determination period on top of the build schedule.
Some garden buildings can be permitted development, but a self-contained annexe with sleeping and bathroom facilities can trigger extra planning considerations. Conservation areas, listed buildings, and maisonettes with shared gardens can also affect what’s allowed. We review your site, intended use, heights and boundaries, then advise on the best route. Our planning support helps you submit the right information and avoid costly redesigns.
We provide a 10-year warranty covering workmanship and key construction elements of your garden annexe. This includes the structural build, weatherproofing details and installation quality, subject to normal use and maintenance. Manufacturer warranties apply separately to items such as glazing, roofing membranes, appliances and sanitaryware. We also hand over documentation for electrics and any relevant plumbing certifications for your records.
We offer contemporary and classic designs, including timber or composite cladding, brick slips to echo period townhouses, and crisp render finishes for modern schemes. Roofing options include warm flat roofs, green roofs, and discreet parapets. Inside, you can choose underfloor heating, built-in storage, acoustic upgrades, and premium kitchenette/bathroom packages. We guide you through layouts, finishes and lighting so the annexe feels proportionate to your garden.
