Chelsea homeowners often need more space but want to stay close to King’s Road and the Saatchi Gallery. A well-designed garden annexe gives you a private, self-contained living area for family, guests or a live-in carer. We create annexes with a bedroom, bathroom and kitchenette, finished to match high-end Chelsea standards. From first sketch to final fit-out, we keep disruption controlled and communication clear.
The Chelsea area features Georgian townhouses, Victorian mansions and luxury apartments, each with different garden layouts and constraints. We’re used to working with tight side access, shared boundaries and premium finishes that suit period architecture. Whether you’re in SW3 near South Kensington or SW10 closer to Fulham, we tailor the annexe footprint and elevations to complement your property. Our insulation, glazing and ventilation choices are made for year-round comfort and low running costs.
Our process starts with a site survey, concept design and a transparent specification covering insulation, electrics, plumbing and internal layouts. You’ll get planning support, clear programme dates and a dedicated project manager coordinating trades. We protect existing paving, planting and access routes, and we keep neighbours in mind with considerate working hours. Fine Landscaping is trusted locally because we deliver premium workmanship, tidy sites and dependable aftercare.
In the Royal Borough of Kensington and Chelsea, access can be restricted and parking is often controlled, so we plan deliveries and skips carefully. Many gardens sit behind listed or heritage-style properties, so sympathetic design and detailing matter. We also account for party walls, boundary lines and neighbour considerations common around Knightsbridge and Pimlico edges. Our team prepares practical drawings and documentation to support smooth approvals and inspections.
Rated 4.9/5 from over 280 verified reviews
Costs in Chelsea vary mainly by size, specification and how much is included in the fit-out. As a guide, a compact, self-contained annexe with insulation, electrics, plumbing, bathroom and kitchenette often starts around £60,000–£90,000. Larger or higher-spec builds with premium cladding, bespoke joinery, underfloor heating and upgraded glazing can reach £100,000–£180,000+. A site survey helps us price accurately for access and groundwork.
Most garden annexes take around 10–16 weeks from start on site to handover, depending on size and complexity. Groundworks, structure, first-fix electrics/plumbing, insulation and internal finishes each add time. Lead times for glazing, doors and bespoke kitchens can also affect the programme. If planning approval or party wall matters are needed, allow additional weeks before construction begins. We provide a clear schedule and regular progress updates.
Some garden buildings can fall under permitted development, but a self-contained annexe with a bathroom and kitchenette may trigger extra scrutiny, especially in conservation areas. In the Royal Borough of Kensington and Chelsea, rules can be tighter due to heritage considerations and garden constraints. We review your site, check permitted development limits, and advise whether a householder application is sensible. Our planning support includes drawings and guidance through the council process.
We provide a 10-year warranty covering workmanship on the build, including key elements such as structure, insulation installation and weatherproofing details. Manufacturer warranties apply separately to items like windows, doors, roofing membranes, boilers or electric heaters, and sanitaryware. At handover, you receive documentation for electrics and plumbing compliance where applicable. If any snagging arises, we respond promptly and schedule remedial work to keep your annexe performing as intended.
We offer a wide range of options, from contemporary cedar or composite cladding to rendered finishes that suit period Chelsea homes. Inside, you can choose layouts with separate bedroom zones, built-in storage, compact kitchenettes and hotel-style bathrooms. Popular upgrades include underfloor heating, acoustic insulation, skylights and large sliding doors. We guide you on materials, glazing and ventilation based on privacy, light levels and how you plan to use the space.
