A garden annexe can turn unused outdoor space into a private suite for family, guests or a home office with overnight comfort. We design and build self-contained annexes across SE11, close to The Oval cricket ground and Kennington Park. Each build can include a kitchenette, bathroom and a dedicated bedroom zone. Insulation, heating-ready construction and secure doors/windows come as standard for everyday use.
Oval’s Georgian townhouses, Victorian terraces and mansion flats often come with compact gardens and shared access routes. We plan annex layouts that respect neighbouring boundaries, light and privacy, while maximising internal storage and usable floor area. In the garden annexes Oval area, we regularly work around period brickwork, mature planting and tight side returns. Finishes are chosen to suit the character of the property, from contemporary cladding to more traditional detailing.
Fine Landscaping handles the full package: survey, concept design, specification, and a managed build with qualified electrics and plumbing. You’ll get clear drawings, a staged programme, and practical planning support where required. We protect paths, lawns and planting, keep noise and waste controlled, and leave the garden clean at handover. Local homeowners choose us for consistent workmanship, straightforward communication and a warranty you can rely on.
Access and parking around Oval tube station can be limited, so we schedule deliveries and waste removal carefully. Many gardens sit behind terraces with narrow side passages, so we design modular components where needed to reduce disruption. We’re familiar with the London Borough of Lambeth approach to planning and constraints, and we’ll advise early if your site sits near sensitive boundaries or has overlooked neighbours. Ground conditions vary, so we specify foundations to suit your soil and drainage.

Costs vary with size, specification and whether you include a full bathroom and kitchenette. As a guide, a compact insulated annexe with electrics typically starts around £35,000–£55,000. A larger, fully self-contained annexe with bathroom, kitchenette, plumbing, higher-end finishes and upgraded glazing often falls between £65,000–£120,000+. Site access, foundations and utility connections in SE11 can also affect the budget.
Most projects take around 6–12 weeks from start on site to completion, depending on size and complexity. Simple insulated rooms can be quicker, while fully self-contained annexes with bathroom, kitchenette and bespoke joinery take longer. Timescales are influenced by access constraints, foundation type, weather, and lead times for windows, doors and sanitaryware. We provide a staged programme before work begins and keep you updated throughout.
Some garden buildings can be permitted development, but a self-contained annexe with sleeping and bathing facilities may require planning permission, especially if it’s intended as a separate dwelling. Rules can also change for listed buildings, conservation considerations, or where height and boundary distances are tight. We review your site, proposed use and design against Lambeth guidance, then provide planning support and drawings if an application is advisable.
We provide a 10-year warranty covering workmanship and key build elements, including structural assembly, weatherproofing and installation quality. Manufacturer warranties apply separately to products such as windows, doors, cladding systems, electrics components and sanitaryware. We also complete commissioning checks for electrics and plumbing so everything operates safely and as intended. If an issue arises, you’ll have a clear point of contact and a documented handover pack.
You can choose from contemporary composite cladding, timber (including treated or charred finishes), brick slips, or render to suit period homes. Inside, popular options include acoustic insulation, underfloor heating-ready floors, fitted storage, and pocket doors to save space. Kitchenettes can range from compact units to full galley layouts, and bathrooms can be shower-room or wet-room style. We guide you through choices based on budget, maintenance preferences and the look of your property.
