Sussex is a county of extraordinary variety, from the rolling chalk ridges of the South Downs to the ancient heathland of Ashdown Forest and the bustling coastal cities of Brighton and Eastbourne. At Garden Office Buildings, we’re proud to serve homeowners across both East and West Sussex, bringing the same bespoke design and build quality that has earned us over 1,000 satisfied customers since 2004.
We work across the county, from the northern towns of East Grinstead, Crawley, and Horsham that sit close to the Surrey and Kent borders, through the Mid Sussex heartland of Haywards Heath, Burgess Hill, and Cuckfield, to Lewes, the historic county town of East Sussex. We also cover the areas around Uckfield, Crowborough, and the villages of the High Weald, as well as reaching into Brighton and Hove and the coastal stretches. Whether you’re in a period cottage overlooking the Downs or a modern family home on a new development, we’ll design a garden room that works for your space.
Sussex gardens come in all shapes and sizes, and we’ve built in the full range. Large rural plots in the Weald and around Ashdown Forest offer wonderful settings for generous garden offices and studios, while the Victorian terraces of Brighton and Lewes present their own design challenges that we relish solving. Suburban family homes in Crawley, Horsham, and Haywards Heath typically have good-sized rectangular gardens that are ideal for a well-proportioned build. See our buildings and prices for the full range, or come to our showroom in Biggin Hill to see the quality for yourself.
Every Sussex build is fully bespoke, designed around your garden from the ground up. We manage the entire process, from the initial site visit through groundworks, construction, electrics, and final handover. Our own team does all the work, and we don’t disappear once the building is finished. We’ve been doing this for over twenty years, and our reputation matters to us.
