Lewisham homeowners want space that works as hard as the rest of the house—especially with fast links from Lewisham station. Our garden rooms are built for everyday use, whether that’s a quiet home office, a garden studio, or an entertainment space. We regularly work across SE13 and nearby streets by Mountsfield Park. Every build is planned to suit your garden’s shape, access and privacy.
From Victorian terraces to Edwardian houses and newer developments, gardens in the Lewisham area come in all sizes and layouts. We design around typical features like narrow side returns, shared boundaries and mature planting. In Ladywell and Hither Green, we often create slimline footprints that still feel spacious inside. If you’re in Blackheath or Lee, we can match materials and proportions to complement period character while keeping performance modern.
We start with a site visit, measured survey and a clear specification, then produce a design that balances light, storage and insulation. Our team handles groundworks, electrics, insulation, glazing and finishes, with tidy site management throughout. You’ll get transparent staging, agreed timelines and a single point of contact from start to handover. Local clients choose us for dependable scheduling, premium detailing and a 10-year warranty for peace of mind.
Access can be tight around terraced streets, so we plan deliveries, waste removal and protection for shared paths. Ground conditions vary near the River Ravensbourne, and we specify suitable bases and drainage where needed. We also consider parking restrictions and neighbour boundaries common in SE13. Where permissions apply, we align designs with London Borough of Lewisham guidance and keep paperwork straightforward.

Most garden rooms in the Lewisham area fall between £10,000 and £40,000 depending on size, insulation spec and finishes. A typical, fully insulated home office or studio is often £15,000–£25,000. Costs rise with larger footprints, premium glazing, fitted storage, bathrooms, or higher-end cladding. We’ll survey your garden and provide a detailed, itemised estimate based on your brief.
A standard build usually takes 2–4 weeks from groundworks to final finishes, assuming straightforward access and settled weather. Timescales can extend if you need extra groundwork, drainage adjustments, bespoke joinery, or complex electrics. Lead times for specialist glazing or cladding can also affect the start date. We agree a programme in advance and keep you updated at each stage.
Many garden rooms can be built under permitted development rules, but it depends on height, placement, overall garden coverage and whether your property has restrictions. Homes in conservation areas or with previous extensions may face additional limits. We check the key criteria and advise what’s likely to apply in the London Borough of Lewisham. If permission is needed, we can help prepare drawings and supporting information.
We provide a 10-year warranty covering workmanship and the structural integrity of the build, giving you confidence in the long-term performance. This includes key elements such as the base, framing, insulation installation and weatherproofing details. Manufacturer warranties apply separately to products like windows, doors and certain cladding systems. We also supply handover guidance so you know how to maintain finishes properly.
You can choose from contemporary or traditional looks, including timber, composite or rendered finishes, plus aluminium or uPVC glazing options. Inside, popular choices include plastered walls, acoustic upgrades for offices, durable flooring for gym rooms, and built-in storage. We can add skylights, wide sliding doors, and smart lighting or heating controls. We’ll guide you through options to match your budget, style and intended use.
