A garden annexe gives you independent space without moving—ideal for guests, grown-up children, or a quiet work-from-home suite. We design and build self-contained garden annexes across SE1 and SE17, with proper insulation, electrics and plumbing as standard. From compact plots near Elephant Park to courtyards around Walworth, we make the most of every metre. Expect a clean, well-managed build with a finish that matches your home.
Elephant & Castle has a mix of modern high-rises, new-build apartments and Victorian terraces, each with different garden access and layout challenges. In Kennington and Borough, we often work with long, narrow gardens and shared boundaries where privacy and light matter. For newer developments near Strata Tower, we plan around tighter access routes, building management rules and noise considerations. Our designs suit both contemporary outdoor spaces and traditional Southwark back gardens.
We start with a site visit, measured survey and a clear scope covering the bedroom, bathroom and kitchenette layout you need. You’ll get transparent staging, tidy working practices, and a single point of contact from design through handover. Our team coordinates groundworks, electrics, plumbing and insulation so the annexe performs year-round. Homeowners choose us for dependable scheduling, premium detailing and straightforward planning support when required.
In the garden annexes Elephant & Castle area, access can be restricted by narrow side returns, shared alleys and controlled parking. We plan deliveries, waste removal and working hours to suit residential streets around Newington and Walworth. Ground conditions and drainage vary across Southwark, so we specify suitable foundations and manage surface water properly. Where properties sit close to neighbours, we design for privacy, boundary compliance and considerate construction.

Costs vary with size, specification and how “self-contained” the annexe is. As a guide, a well-insulated garden room can start around £35,000–£55,000, while a fully self-contained annexe with bathroom, kitchenette, electrics and plumbing is often £70,000–£130,000+. Complex access in SE1/SE17, higher-end finishes, and upgraded foundations can increase budgets. We provide an itemised estimate after a site survey.
Most projects take around 6–12 weeks on site once the design is agreed and materials are ordered. Larger annexes with a full bathroom and kitchenette, or those needing more extensive groundworks and drainage, can run 12–16 weeks. Timescales are also affected by access constraints, neighbour considerations, and any planning or building control requirements. We set a programme upfront and keep you updated at each stage.
Some garden buildings can be permitted development, but a self-contained annexe with sleeping, bathroom and kitchen facilities can trigger additional planning considerations. Southwark rules may also be affected by conservation areas, previous extensions, height limits, and proximity to boundaries. We review your property, advise on the likely route, and can prepare drawings and supporting information. Where needed, we help you through the planning application process.
