Keston homeowners want space that works as hard as they do—without sacrificing the garden. Our garden offices are built for comfortable, all-season use, ideal for remote work, meetings or creative studios. Whether you’re close to Keston Common or a short walk from Keston Ponds, we tailor the layout to your outlook, privacy and access. Every build is finished to a premium standard, ready to furnish and start using.
The Keston area includes everything from period cottages to large detached houses and country homes, often with generous plots and mature planting. We’re used to working around established lawns, trees and existing patios, keeping disruption low and finishes tidy. Many BR2 gardens benefit from a dedicated workspace that doesn’t compromise the character of the main house. We also regularly work across Hayes, Farnborough and Downe, so we understand the local styles and expectations.
We start with a site visit to confirm position, levels, access routes and services, then produce a clear design and specification. Your garden office includes proper foundations, insulation, electrics and heating, plus security and sound proofing options where needed. We keep you informed from groundworks to final fit-out, with clean working practices and careful handover. Fine Landscaping is based in Norbury—around 30 minutes away—so support and aftercare are close at hand.
Gardens in Keston can include sloping sections, mature roots and varied ground conditions, so we specify foundations to suit the site rather than guess. We plan deliveries and access carefully, especially where lanes are tighter or parking is limited. For projects in the London Borough of Bromley, we can advise on siting, height and boundary distances to help you stay within the rules. The result is a garden office that looks right with local property styles and performs properly in all seasons.

Costs vary by size, specification and access, but most garden offices in the Keston area start from around £18,000–£30,000 for a compact, fully insulated room with electrics. Larger bespoke designs with premium cladding, higher-spec glazing, heating upgrades, sound proofing and complex foundations often fall in the £35,000–£60,000+ range. We provide a detailed breakdown after a site visit so you can compare options confidently.
A typical build takes around 3–6 weeks from breaking ground to completion, depending on size and the level of fit-out. Groundworks and foundations can take longer if levels need adjusting or access is restricted. Bespoke joinery, specialist glazing, or additional sound proofing may extend lead times. We’ll confirm a realistic programme after surveying the site and agreeing the specification and finish schedule.
Many garden offices fall under permitted development, provided they meet limits on height, footprint, and where they sit in relation to boundaries and the main house. However, rules can change if your property is listed, in a conservation area, or if previous extensions have used up allowances. We’ll review the proposal against London Borough of Bromley guidance and advise if a lawful development certificate or planning application is sensible for peace of mind.
We supply a 10-year warranty covering the core build elements, including structural integrity, weatherproofing and workmanship. This gives you long-term reassurance that the building will remain robust, dry and fit for purpose. Manufacturer warranties also apply to specific components such as doors, windows, cladding systems, heaters and electrical parts where relevant. We’ll explain what’s covered and provide documentation at handover.
We offer bespoke designs with a range of finishes, including timber cladding (cedar or larch), composite boards, and contemporary rendered panels. Inside, popular options include plastered walls for a “home office” feel, acoustic lining for sound reduction, and integrated storage. You can choose glazing styles, roof types, security upgrades and heating solutions to match how you’ll use the space. We guide you through choices to balance looks, performance and budget.
