Honor Oak homeowners often want extra space without moving, especially near Honor Oak Park station and the slopes of One Tree Hill. A garden annexe gives you a private, fully usable extension at the end of the garden—ideal for family, guests or a quiet workspace. Our builds can include a kitchenette, bathroom and a separate bedroom zone. Everything is designed to look right with your home and garden.
We regularly work across SE23 and nearby Forest Hill and Brockley, where gardens vary from long Victorian plots to compact side returns. Victorian terraces, Edwardian houses and 1930s semis each bring different constraints—party boundaries, mature trees, and existing outbuildings. We plan the footprint, access and services to suit your property type. The result is a garden annexe that feels like part of the home, not an afterthought.
Fine Landscaping manage the full process: survey, concept design, specification, and a clear programme from groundworks to final fit-out. You’ll get compliant electrics and plumbing, robust insulation, and tidy site management with respectful neighbours in mind. We provide planning support and handle the practical details that slow projects down. As we’re only around 20 minutes away, aftercare and snags are dealt with quickly.
The garden annexes Honor Oak area often involves sloping plots and stepped levels, especially near One Tree Hill, so we design foundations and drainage to suit. Access can be tight on residential streets, so deliveries and waste removal are planned to minimise disruption and parking issues. For garden annexes in London Borough of Lewisham, we also consider conservation constraints, trees, and neighbour sightlines. Our team adapts layouts and finishes to match SE23 period homes and modern upgrades.

Costs vary mainly by size, specification and how far services need to run. As a guide, a compact insulated annexe with electrics can start from around £35,000–£55,000. A fully self-contained unit with kitchenette, bathroom, plumbing and higher-end finishes is often £60,000–£120,000+. Ground conditions, sloping gardens, and bespoke glazing or cladding can increase the budget. We provide a detailed, itemised estimate after a site visit.
Most projects take 6–12 weeks from start on site to handover, depending on size and complexity. Simple shells with basic fit-out can be quicker, while self-contained annexes with bathroom, kitchenette, and bespoke joinery take longer. Timescales are affected by groundworks, drainage connections, access for materials, and lead times for windows, doors and specialist finishes. We give a clear programme and keep you updated throughout the build.
Some garden buildings can fall under permitted development, but a self-contained annexe used as separate accommodation can trigger additional planning considerations. Height, boundary distances, overall footprint, and whether the property has restrictions (such as conservation area controls) all matter. We review your site, advise on the safest route, and provide planning support where needed. If permission or certificates are required, we help prepare drawings and documentation.
We provide a 10-year warranty covering workmanship and key elements of the build, including structural assembly and weatherproofing. Electrical and plumbing work is carried out by qualified trades and certified where required, with manufacturer warranties passed on for products and appliances. If any snagging issues arise after handover, we schedule prompt remedial visits. Clear documentation and maintenance guidance are included so your annexe performs as intended long-term.
You can choose from contemporary or more traditional styles to suit Victorian, Edwardian or 1930s homes. Popular options include timber or composite cladding, brick slips, standing-seam metal details, and large sliding or bi-fold doors. Inside, we can fit compact kitchenette runs, shower rooms, built-in storage and acoustic upgrades for quiet working. We’ll guide you through layouts, finishes and energy-efficient heating so the annexe matches your needs and budget.
