Sydenham homeowners want workspace without losing the character of their gardens, especially near Sydenham Wells Park and the SE26 streets of period homes. Our garden offices are designed to look sharp from the house and feel calm inside, whether you’re taking calls or focusing on deep work. Every build is insulated, sound managed, and finished to a premium standard. You get a dedicated office that’s separate from the main house, yet fully connected.
We regularly work across the garden offices Sydenham area, including Forest Hill and Lower Sydenham, where plots can be long, narrow, and bordered by mature planting. Victorian villas, Edwardian houses, and period conversions often need sympathetic designs that don’t overwhelm the garden. We plan layouts around existing patios, trees, and access routes, keeping disruption low. The result is a bespoke building that suits both the property and the neighbourhood.
Fine Landscaping handles the full process: survey, foundations, design, build, electrics, heating, and final detailing. We’ll advise on planning early, confirm practicalities like access and cable routes, and keep you updated with clear milestones. Our team is local—about 20 minutes away—so aftercare and snagging are straightforward. Homeowners choose us for tidy working, durable materials, and a finish that stays solid through every season.
Across the London Borough of Lewisham, gardens can vary from clay-heavy ground to made-up areas near older extensions, so we specify foundations to suit the site, not a template. Parking and access can be tight around Bell Green and SE26 side roads, so we plan deliveries and waste removal to minimise disruption. We also design around established trees and boundaries common near Dulwich Wood and Sydenham Hill Wood. You get a build that respects neighbours, levels, and local constraints.

Most garden offices in Sydenham fall between £15,000 and £40,000 depending on size, insulation spec, glazing, and internal fit-out. A compact, well-insulated office with electrics typically starts around £15,000–£22,000. Larger bespoke designs with upgraded sound proofing, heating options, premium cladding, and more complex foundations can be £25,000–£40,000+. We’ll survey your garden and provide a detailed, itemised estimate.
A typical build takes 2–6 weeks from breaking ground to final finish, depending on design complexity and site access. Simple, smaller offices with straightforward foundations can be completed in around 2–3 weeks. Larger bespoke buildings, extra glazing, sound proofing, or tricky access (common with long Sydenham plots) can extend timelines. Planning checks, lead times for materials, and weather can also affect the schedule.
Many garden offices are allowed under permitted development, provided they meet limits on height, placement, and use, and aren’t intended as a separate dwelling. However, rules can change for listed buildings, conservation considerations, or if your property has previous development restrictions. We provide planning advice, review the proposed location and dimensions, and can recommend when a lawful development certificate is sensible for peace of mind before work begins.
We provide a 10-year warranty covering the structural build, including the integrity of the main frame, roof construction, and weatherproofing when installed and maintained as specified. Manufacturer warranties apply to components such as doors, windows, and cladding finishes, and electrical work is certified to current regulations. If any snagging issues appear after completion, our local team can respond quickly and put things right.
We offer bespoke designs with a choice of contemporary or traditional finishes to suit Sydenham’s period homes.

Inside, you can choose plastered walls, durable flooring, and tailored storage. We’ll guide you on layout, window placement for privacy, and heating choices so the space works year-round.
