If you want extra space that feels like part of the home, a garden room is a smart upgrade for Biggin Hill properties. We design and build bespoke rooms for home offices, studios, gyms and entertainment spaces with proper insulation and electrics. Many clients near Biggin Hill Airport and the RAF Memorial choose garden rooms to work from home in peace. We cover TN16, including Aperfield and Berry's Green.
Biggin Hill’s semi-rural setting means gardens are often generous, making it ideal for a well-proportioned garden studio or summer house. We regularly work on large detached houses, bungalows and period properties where access, levels and existing outbuildings vary. Our designs suit both traditional homes and modern extensions, keeping proportions and finishes in balance. For families, a separate space can reduce noise in the main house and protect resale appeal.
We start with a site visit to measure, check access, and talk through how you’ll use the room day to day. You’ll receive a clear specification, build schedule and fixed scope, with tidy working practices throughout. From groundworks to insulation, glazing and internal finishes, everything is managed by our team so the project stays on track. Local homeowners choose us for reliable communication, premium materials and a 10-year warranty.
Across the London Borough of Bromley, gardens can be sloped and ground conditions vary, especially around the higher points near Biggin Hill. We plan foundations and drainage to suit the site, then set finished floor levels so the room feels integrated with the garden. Parking and access can be tight on some lanes around Cudham and Berry's Green, so we schedule deliveries carefully and keep the site organised. The result is a clean build and a room that performs properly in all seasons.

Most garden rooms in Biggin Hill fall between £10,000 and £40,000, depending on size, insulation level, glazing, and internal fit-out. A typical project is £15,000–£25,000 for a fully insulated room with electrics, lighting and a quality finish. Extras such as bathrooms, air conditioning, premium cladding, or complex groundworks can increase the budget. We provide a detailed specification so you can compare like-for-like.
Garden rooms are usually completed in 2–4 weeks from the start of on-site work, depending on the design and the amount of groundwork required. Sloping gardens, restricted access, or upgrades like large sliding doors and higher-spec insulation can extend the programme. We confirm lead times for materials and agree a clear schedule before starting. You’ll know what’s happening each week, with tidy handover at the end.
Many garden rooms can be built under permitted development rules, but it depends on factors such as height, position in the garden, and whether the room is for incidental use. If your property has restrictions, is listed, or sits in a sensitive area, the rules may differ. We review the proposed design against current guidance and can advise on whether a planning application is sensible. If needed, we’ll help you prepare the information required.
We provide a 10-year warranty covering workmanship and key structural elements of the build, giving you confidence that the room will stay solid, weather-tight and fit for purpose. This includes items such as the base, framing, insulation installation and external envelope. Manufacturer warranties also apply to specific products like windows, doors and cladding where relevant. We’ll explain what’s covered in writing before work begins.
You can choose from modern composite cladding, timber cladding, or rendered finishes to suit your home, plus aluminium or uPVC glazing options. Inside, popular choices include plastered walls, acoustic upgrades for office use, and durable flooring for gym rooms. Roof options can include flat or mono-pitch designs with high-performance membranes. We’ll guide you through layouts, lighting, sockets and heating so the room works perfectly for how you’ll use it.
