A garden annexe is a practical way to gain a private, self-contained space without moving. In SE15, we design and build annexes that include a bedroom area, bathroom and kitchenette, finished to a high standard. Homeowners near Peckham Rye Park and Queen’s Road often choose an annexe for multigenerational living, home working or hosting. Every build is tailored to your garden’s layout and access.
Peckham’s housing mix—Victorian terraces, Georgian houses and converted warehouses—brings different constraints and opportunities. We’re used to narrow side returns in Nunhead, varied boundary lines in East Dulwich, and shared access arrangements common across Southwark. Our designs respect neighbouring sightlines and maximise natural light. The result is a garden annexe that feels like a proper small home, not a temporary outbuilding.
From the first site visit to handover, we manage the full build: foundations, structure, insulation, electrics and plumbing, then the internal fit-out. You’ll get clear specifications, staged payments and tidy working practices to keep disruption down. We also provide planning support and liaise with your chosen inspector for Building Regulations sign-off. Fine Landscaping is based just 25 minutes away, so aftercare is straightforward.
Across the London Borough of Southwark, gardens can be compact with limited access and controlled parking for deliveries. We plan logistics around permit bays, school-run traffic and narrow streets near Peckham Library and Camberwell borders. Ground conditions vary, so we specify foundations to suit and protect nearby structures. Our team adapts designs to period properties and boundary constraints typical in the garden annexes Peckham area.
Rated 4.9/5 from over 280 verified reviews
Costs in SE15 vary mainly by size, specification and how “self-contained” you want it. As a guide, a well-insulated annexe with electrics and basic finishes often starts around £45,000–£70,000. Adding a full bathroom, kitchenette, higher-end cladding, underfloor heating and bespoke glazing can take budgets to £80,000–£130,000+. We provide a detailed breakdown after a site survey.
Most builds take around 8–14 weeks on site once designs and approvals are in place. Smaller annexes with simpler fit-outs can be quicker, while larger units with bathroom, kitchenette, complex drainage runs or restricted access may take longer. Lead times for windows, doors and specialist finishes can also affect the schedule. We set a realistic programme and keep you updated at each stage.
Some garden buildings can fall under Permitted Development, but a self-contained annexe with sleeping, bathroom and kitchenette often needs closer checks. Restrictions can apply due to height, proximity to boundaries, conservation areas, or how the space will be used. We review your property, confirm what’s likely to be required, and provide planning support where needed. We also help ensure Building Regulations compliance.
We provide a 10-year warranty covering workmanship and the structural build elements of your annexe, giving peace of mind long after completion. This includes key construction components such as the frame, insulation installation, weatherproofing and external finishes when installed by our team. Manufacturer warranties apply separately to products like windows, doors, electrics and heating systems. We also offer prompt aftercare for any snagging issues.
You can choose from contemporary or more traditional styles to suit Victorian terraces and Georgian homes. Popular options include composite cladding, timber (cedar or larch), brick slips, and standing-seam metal details, plus large sliding doors or corner glazing. Internally, we can fit compact kitchenettes, tiled bathrooms and built-in storage for a bedroom zone. We guide you through layouts, finishes and energy-efficient upgrades to match budget and use.
