Need extra space in W6 for family, guests or a quiet place to work? Our garden annexes are designed to feel like a proper small home, with a kitchenette, bathroom and comfortable bedroom zone. We regularly work near King Street and along the riverside routes by Hammersmith Bridge, so we understand the practicalities of building in busy streets. The result is a warm, private annexe that fits your garden and your lifestyle.
Hammersmith’s mix of Victorian terraces, mansion flats and modern riverside developments often comes with compact gardens and tight access. We plan layouts that make every square metre work, from smart storage to light-filled glazing. If you’re in Brook Green, Fulham or close to Shepherd's Bush, we’ll tailor the build to your boundary conditions and neighbouring sightlines. Good insulation and ventilation are prioritised so the space stays comfortable year-round.
Fine Landscaping handles the project end-to-end: survey, concept design, specification, groundworks, structure, insulation, electrics, plumbing and final finishes. You’ll get clear staging, tidy site management and straightforward communication throughout. We also provide planning support, including permitted development checks and documentation where needed. Many local homeowners choose us because we build like professionals and finish like craftsmen.
Across the London Borough of Hammersmith and Fulham, access can be narrow and parking controlled, so we plan deliveries, skips and working hours carefully. Many gardens sit behind Victorian terraces where party walls, drainage runs and boundary lines need accurate setting-out. We assess ground conditions, existing services and levels before finalising foundations and plumbing routes. If you’re in the garden annexes Hammersmith area near busy roads, we also consider acoustic performance and privacy.

Costs vary with size, specification and how self-contained you want it. As a guide, a compact insulated annexe with electrics and basic finishes often starts around £45,000–£70,000. A higher-spec build with kitchenette, full bathroom, upgraded glazing, heating and bespoke joinery commonly falls between £75,000–£120,000+. Restricted access in W6, drainage complexity and premium finishes can increase the budget.
Most builds take around 8–14 weeks on site once designs and approvals are in place. Smaller, simpler structures can be quicker, while annexes with full plumbing, bathroom fit-out and bespoke interiors take longer. Timescales depend on access for materials, groundworks complexity, utility connections, and lead times for windows, kitchens and sanitaryware. We provide a staged programme so you can plan around disruption.
Some garden buildings can be permitted development, but an annexe used as independent accommodation can trigger additional rules. In the London Borough of Hammersmith and Fulham we check height, footprint, boundary distances, overlooking, and whether the property has restrictions or is in a conservation area. We’ll advise what’s feasible, prepare drawings, and support any application if required, so you avoid costly redesigns later.
We provide a 10-year warranty covering structural workmanship and installation quality for the annexe build. This includes key elements such as foundations, framing, insulation build-up, external cladding installation and weatherproofing details. Electrical and plumbing works are carried out by qualified trades and certified accordingly, with manufacturer warranties applying to products like windows, doors and roofing systems. We also offer a clear snagging process after completion.
You can choose from contemporary or more traditional looks to suit local streetscapes, including timber cladding, composite boards, brick slips or rendered finishes.
