Response within 24 hours
Thornton Heath homeowners are choosing garden offices to gain space for work, study or a side business—without sacrificing a bedroom. Whether you’re near Thornton Heath station or walking distance from Thornton Heath Pond, we design buildings that look smart and perform all year round. Every build is insulated, wired and finished to a premium standard. We also make sure it’s internet-ready, so you can plug in and get on with your day.
CR7 gardens often sit behind Victorian terraces, Edwardian semis and 1930s houses, each with different access and layout challenges. We plan around narrow side returns, shared boundaries and existing patios, keeping disruption low. If you’re in Broad Green or close to Selhurst, we’ll tailor the footprint and roofline to suit neighbouring sightlines and garden proportions. The result is a garden office that feels like a natural extension of your home.
We start with a site visit, then produce a clear design and specification covering foundations, insulation, electrics, heating and security. Our team manages the build end-to-end, with tidy working practices and straightforward communication throughout. You’ll receive planning advice where needed, plus a written 10-year warranty for peace of mind. Being only 5 minutes away means we can respond quickly and keep your project moving.
Across the London Borough of Croydon, we regularly work with mixed ground conditions and gardens that need robust, level foundations. Thornton Heath streets can mean tighter access and limited parking, so we plan deliveries and waste removal carefully. We also account for party walls, boundary lines and mature planting common in older CR7 plots. This local experience helps us avoid delays and deliver a cleaner finish.

Costs vary by size, specification and access. As a guide, a compact insulated office with electrics typically starts from around £12,000–£18,000. Mid-sized, fully finished garden offices with heating, upgraded glazing and better sound proofing often fall between £18,000–£30,000. Larger bespoke designs with premium cladding, extra security, WC plumbing or complex foundations can be £30,000+. We provide a detailed, itemised quote after a site visit.
Most projects take 3–6 weeks from start on site to completion, depending on the foundation type, size and internal fit-out. Simple bases and standard specifications can be quicker, while bespoke designs, sound proofing, upgraded electrics or tricky access can add time. We’ll confirm lead times after surveying your garden and agreeing the design. If planning checks are required, we factor that in before scheduling the build.
Many garden offices can be built under permitted development, provided they meet limits on height, placement and overall garden coverage. However, rules can change with listed buildings, conservation considerations, or if you plan to use the space as separate accommodation. We’ll review your site, intended use and design, then advise on whether planning is likely. If needed, we can help you prepare details for Croydon’s planning process before work begins.
We back our builds with a 10-year warranty covering workmanship and key structural elements, including the building shell and installation quality. If an issue arises due to our construction—such as defects in assembly, fixings or weatherproofing—we’ll put it right. Manufacturer warranties also apply to many components like doors, windows and certain insulation products. We’ll explain what’s covered in writing, along with care guidance to protect your finish long-term.
Your garden office can be tailored to your style and budget. Popular choices include composite or timber cladding, contemporary aluminium trims, and a range of glazing options for light and privacy. Inside, we can specify extra insulation, acoustic layers for sound proofing, and finishes such as plasterboard, panelling or built-in storage. Roof types can be flat or pitched, depending on height limits and aesthetics. We’ll guide you through options and recommend what suits your garden best.
