Earl’s Court homeowners often need extra space without the upheaval of moving. Our garden annexes create a private, self-contained room for guests, older relatives, or a dedicated workspace. We regularly work near Earl’s Court tube station and around Philbeach Gardens, where gardens vary from compact courtyards to generous rear plots. Every build is tailored to your layout, access and lifestyle.
The local housing mix—Victorian mansion conversions, period flats and garden square properties—brings specific constraints and opportunities. Party walls, shared boundaries and limited side access are common in Kensington and West Brompton. We design annexes that respect neighbouring outlooks while maximising internal comfort with proper insulation and efficient heating. Finishes are chosen to complement Victorian architecture and contemporary interiors alike.
We start with a site survey, then produce a clear specification covering foundations, insulation, electrics and plumbing. You’ll receive a staged programme, tidy working practices and transparent communication throughout. Our team coordinates trades so the kitchenette, bathroom and bedroom elements integrate seamlessly. Homeowners choose Fine Landscaping for dependable project management and a premium finish that lasts.
Working in the Royal Borough of Kensington and Chelsea means careful attention to access, parking restrictions and neighbour considerations. In SW5, deliveries and waste removal often need timed planning, especially near the Earl’s Court Exhibition Centre site and main routes. We adapt build methods for confined gardens, protect existing paving and planting, and keep sites orderly. Our designs also suit period property settings, helping annexes look intentional rather than bolted on.

Costs vary with size, specification and site access. As a guide, a compact, insulated studio-style annexe with electrics can start from around £35,000–£55,000. A fully self-contained build with kitchenette, bathroom, upgraded glazing and higher-end finishes is often £60,000–£110,000+. Restricted access, bespoke joinery and complex drainage connections can increase the budget.
Most projects take around 6–12 weeks from start on site to handover, depending on complexity. Smaller annexes with straightforward foundations and simple services can be quicker, while larger self-contained layouts with bathroom plumbing, kitchen fit-out and bespoke glazing take longer. Timescales are also affected by access in SW5, lead times for materials, and any planning or party wall requirements.
Some garden buildings can fall under permitted development, but a self-contained annexe with sleeping and bathroom facilities may trigger additional rules. In Kensington and Chelsea, constraints such as conservation areas, listed buildings, and limits on height, footprint and boundary proximity can apply. We review your property, check local guidance, and provide planning support so you proceed with the right approvals and documentation.
We provide a 10-year warranty covering workmanship and key structural elements of the annexe build. This includes items such as the building shell, insulation installation, weatherproofing and core construction details. Manufacturer warranties apply separately to products like windows, doors, cladding and roofing membranes. We also hand over clear care guidance and remain available for post-completion support if anything needs attention.
You can choose from contemporary or period-friendly designs, with options such as timber or composite cladding, brick slips, standing-seam metal roofing, and high-performance aluminium or timber windows. Internally, we can fit compact kitchenette units, tiled shower rooms, built-in storage and underfloor heating. We’ll help you select finishes that suit your home’s Victorian character, your budget, and the level of privacy needed from neighbouring properties.
