A garden annexe can add real flexibility to your home in SE12, whether you need space for relatives, grown-up children or a quiet work-and-sleep setup. We build fully self-contained units with a kitchenette, bathroom and bedroom, tailored to your plot. From the Lee Green crossroads to homes near Manor House Gardens, we plan layouts that make the most of light, privacy and garden access. Every build is finished to a high standard, ready to use from day one.
Lee Green has a mix of Victorian terraces, Edwardian semis and 1930s houses, often with long rear gardens that suit an annexe footprint. We’re used to working around shared side access, existing patios, and mature planting that homeowners want to keep. If you’re close to Lee station or Leegate Shopping Centre, we’ll factor in access routes for deliveries and considerate working hours. Our garden annexes Lee Green area designs respect neighbouring boundaries while maximising internal comfort.
Fine Landscaping manages the full process: survey, concept design, specification, and build, including electrics and plumbing. You’ll get clear stages, realistic timescales, and tidy site management, with regular updates throughout. We also provide planning support, advising on permitted development and any constraints before you commit. Local homeowners trust us for reliable workmanship, transparent options, and a finish that looks like it belongs with the main house.
In Lee Green, access can be tight behind terraces and semis, so we plan deliveries, waste removal and storage carefully. We also consider drainage runs, existing manholes and levels common in SE12 gardens, keeping disruption to a minimum. Parking and neighbour proximity are factored into our working plan, especially near Lee station. We tailor foundations and services routes to suit each property style and garden layout in the London Borough of Lewisham.
Rated 4.9/5 from over 280 verified reviews
Costs vary with size, specification and how “turnkey” you want the annexe. As a guide, a compact insulated annexe with electrics and basic finishes may start around £60,000–£90,000. A larger, fully self-contained unit with kitchenette, bathroom, higher-end glazing, upgraded heating and bespoke joinery is often £100,000–£160,000+. Groundworks, drainage runs and access constraints in SE12 can affect the total.
Most garden annexes take around 8–14 weeks on site once the design and specification are agreed. Smaller builds with straightforward access and short plumbing runs can be quicker, while larger annexes with complex groundworks, bespoke interiors and multiple service connections take longer. Lead times for windows, doors and kitchens also influence the schedule. We provide a staged programme so you know what’s happening each week.
Some garden outbuildings can fall under permitted development, but a self-contained annexe intended for independent living can trigger extra rules. In the London Borough of Lewisham, factors like overall height, distance to boundaries, garden coverage, and intended use all matter. We review your site, advise on the most suitable route, and provide planning support where needed. If permission is required, we help prepare drawings and information for submission.
We provide a 10-year warranty covering workmanship and build quality for your garden annexe structure and installed elements completed by our team. This includes key construction components and finishing standards, subject to normal use and maintenance. Manufacturer warranties also apply to specific products such as windows, doors, insulation systems and sanitaryware. You’ll receive documentation at handover, plus clear guidance on care to keep everything performing well.
You can choose from contemporary or more traditional styles to suit Lee Green’s Victorian and 1930s homes.

Inside, we can fit compact kitchenette layouts, walk-in showers, built-in storage and underfloor heating or efficient electric heating. We’ll guide you through finishes, durability and budget, then finalise a specification that fits your garden and lifestyle.
