A Garden Room is distinct from a summerhouse because it is engineered for 365-day use. While a summerhouse is a single-skin timber building, our Garden Rooms function as detached home extensions. They feature thermal insulation (in walls, roof, and floor), residential-grade double glazing, and EPDM rubber roofing to retain heat in winter and stay cool in summer. Whether you need a Home Office, gym, or art studio, these buildings provide the stable internal climate required for expensive electronics and year-round comfort.
Garden rooms give you flexible, year-round living space without the cost and disruption of a traditional extension. These timber buildings transform how you use your garden, creating dedicated space for home offices, fitness studios, art workshops, or simply a quiet retreat from family life. If you are looking for a simpler building specifically for warm weather relaxation, our Summerhouses collection offers a cost-effective alternative.
Our collection includes insulated garden rooms with 50mm wall thickness for winter warmth, modern designs with floor-to-ceiling glass, and corner models that maximise awkward plots. Every garden room features pressure-treated timber for 25-year rot resistance, UPVC double-glazed windows with toughened safety glass, and EPDM rubber roofing that lasts 50+ years. All timber products include our 10 Year Warranty, plus free UK mainland delivery and professional installation service available nationwide.
Home Office & Studios: 68% of our customers buy garden rooms for remote working. A dedicated 10x8ft office keeps work separate from home life, with proper insulation maintaining 18-22°C without constant heating.
Insulation Levels: Uninsulated summerhouse-style rooms cost from £3,329 but suit summer use only. Insulated models (£6,000+) with 50mm walls and double glazing maintain comfortable temperatures year-round, cutting heating costs 40% versus single-skin buildings.
Note: Insulation adds £2,000-£4,000 but saves £300+ yearly on heating. Electrics cost £800-£1,500 professionally installed.
Structural Timber: Pressure-treated 44mm framing provides the skeleton. Better models use 56mm framing for strength. Tongue-and-groove cladding creates weatherproof walls.
Glazing Standards: All our garden rooms include UPVC double-glazed units with 4mm toughened safety glass. Argon-filled gaps improve thermal efficiency by 30%.
Roofing Systems: EPDM rubber membranes last 50+ years with zero maintenance, outperforming felt significantly.
Why We Chose This Range
“We stock Palmako and Lichfield garden rooms because they don't cut corners on the Roof Insulation. Heat rises; a garden room with insulated walls but a thin roof will be freezing in January. Our curated models use proper EPDM rubber roofing and allow for 50mm+ of Celotex or Rockwool insulation in the ceiling cavity, ensuring your heater isn't just warming up the winter sky.”
— Matt, Founder of Greenhouse StoresOur installation teams build the structure, but you need a plan for power. You cannot just run a standard extension lead down the garden.
Before your base is laid, plan where your Steel Wire Armoured (SWA) cable will enter the building. It usually needs to run underground from your house consumer unit. If you are pouring a concrete base, you must install a cable duct (a plastic pipe) through the concrete before it sets, otherwise, you'll have unsightly cables running up the outside of your beautiful new office.
Most garden rooms fall under "Permitted Development" if they are under 2.5m high (eaves height) and located within 2m of a boundary. If they are further than 2m from a boundary, they can be up to 4m high. However, if you live in a Listed Building or Conservation Area, check with your local council.
Yes, provided you choose an insulated model. Our garden offices feature double glazing and insulated walls/roofs, making them comfortable even in winter. Uninsulated "log cabins" are generally suitable for Spring-Autumn use only unless you retrofit insulation.
WiFi signals struggle to penetrate insulated foil-backed walls. We recommend running an external-grade CAT6 Ethernet cable alongside your power cable for a hardwired connection, or using a Powerline Adapter kit if your home's wiring allows it.
A garden room requires a substantial foundation. We recommend a concrete slab (100mm thick) or a specialist ground screw system. Unlike sheds, garden rooms are too heavy for simple paving slabs on sand. The base must be perfectly level to ensure doors and windows operate correctly.
Professional installation typically costs 15-20% of the building's value. Our service includes full assembly, roofing installation, and glazing fitting. DIY installation is possible but requires 2-3 people and 2-3 days for a standard sized room.
