Garden Rooms
We stock 57 garden rooms priced from £2,199 for the Palmako Karl carport to £29,000 for the Lichfield Crown Elegant Home Sauna, covering insulated pods, log cabins, corner cabins, octagonal rooms, saunas, garages, carports, and garden shelters. Every timber building uses pressure-treated wood with a 10-year warranty. Insulated models feature double-glazed windows and EPDM rubber roofing rated for 50+ years. We have fitted garden buildings across the UK since 2012.
For insulated-only options, see our insulated garden rooms. For warm-weather buildings without insulation, browse our summerhouses.
About Our Garden Rooms
A garden room is not a shed with a window. It is a detached building engineered for 365-day use. Our range includes insulated pods from Calmpod, Nordic spruce log cabins from Palmako, premium timber rooms from Lichfield, steel-framed buildings from Telluria, and glass orangeries from Janssens. Prices start at £2,199 for the Palmako Karl carport and run to £29,000 for the Lichfield Crown Elegant Home Sauna. When we fit these buildings, we see the difference proper insulation, double glazing, and EPDM roofing make to year-round comfort.
If you want a seasonal summer space rather than a year-round room, our summerhouses start from a lower price point. For compact options under 3m wide, see our small garden rooms collection.
Why We Chose This Range
"I test every brand we stock by looking at three things: roof insulation thickness, glazing quality, and timber treatment. Heat rises, so a garden room with insulated walls but a thin roof will freeze you out by November. Our Calmpod range uses 100mm sandwich panel insulation. The Palmako cabins use slow-grown Nordic spruce that holds screws better than fast-grown pine. The Lichfield buildings use 44mm+ walls with proper chalet-cut corners for wind resistance. I will not stock a building that cuts corners on any of those three."
— Matt, Founder of Greenhouse Stores (fitting garden buildings since 2012)Types of Garden Room We Offer
Insulated Garden Rooms
Best for: home offices, studios, therapy rooms. The Calmpod insulated garden rooms use 100mm sandwich panel walls with U-values matching a modern house extension. Double-glazed windows and EPDM rubber roofing come as standard. Three sizes: 8x8, 8x12, and 12x8. Prices from £9,799.
Apex Log Cabins
Best for: maximum headroom and classic aesthetics. The pitched roof creates vaulted ceilings and superior rainwater runoff. Browse our full apex garden rooms range from Palmako and Power. Wall thicknesses from 28mm to 44mm. Sizes from 3m x 2.4m to 20x18ft.
Pent & Modern Garden Rooms
Best for: planning-friendly builds near boundaries. Single-slope roofs stay under 2.5m total height, keeping most builds within permitted development. Our pent garden rooms and modern garden rooms feature clean architectural lines with EPDM rubber roofing.
Corner & Octagonal Rooms
Best for: reclaiming dead corner space or creating a garden focal point. Our corner garden rooms slot into 90-degree garden corners. Octagonal garden rooms offer panoramic views with hub-and-spoke roof construction for wind resistance.
Metal Garden Rooms
Best for: zero-maintenance and boundary builds. Our metal garden rooms from Telluria use composite sandwich panels: two sheets of galvanised steel bonded to insulated core. Rot-free, fire-retardant, and the only option permitted within 1m of a boundary under fire regulations. 20-year warranty.
Home Saunas
Best for: wellness and relaxation. Our home saunas from Palmako range from compact 0.9m barrel-style units to the 8.2m Grace sauna room. Built from Nordic spruce with proper ventilation systems. Prices from £2,325.
Quick Guide: Which Garden Room Do You Need?
Home office: Choose an insulated model (Calmpod or Lichfield) with double glazing. Run SWA armoured cable underground for power and a CAT6 ethernet cable for reliable internet.
Gym or studio: Choose a metal garden room (Telluria) for load-bearing floors and fire safety, or a large apex cabin (Power 20x18) for headroom.
Seasonal retreat: A Palmako log cabin (28mm walls) or a summerhouse will do the job at a lower price. No insulation needed if you only use it April to October.
Matt's Installation Tip: Plan Your Electrics Before the Base
You cannot run a standard extension lead down the garden for a permanent building. Before your concrete base is poured, plan where your Steel Wire Armoured (SWA) cable will enter the building. Install a plastic cable duct through the concrete before it sets. If you skip this step, you will have cables running up the outside of your new office. A Part P qualified electrician must connect the supply. Budget £800-£1,500 for the electrical work.

Planning Permission: Do You Need It?
Most garden rooms fall under permitted development and do not need planning permission. The key rules for England and Wales:
- Maximum height: 2.5m at the eaves if within 2m of a boundary. Up to 4m for a dual-pitched roof if further than 2m from any boundary.
- Ground coverage: All outbuildings combined must not exceed 50% of your total garden area (excluding the footprint of the original house).
- Position: Must be in the rear or side garden. Not forward of the principal elevation.
- Use: Must be incidental to the enjoyment of the dwelling. A home office or gym counts. A self-contained flat does not.
Exceptions: Listed buildings, conservation areas, AONBs, and National Parks have stricter rules. Always check with your local planning authority if you are unsure. Read our full planning permission guide for the complete checklist.
Frequently Asked Questions
-
Do garden rooms need planning permission in the UK?
Most garden rooms are permitted development and need no planning application. Your building must stay under 2.5m at the eaves if within 2m of a boundary, and under 4m at the ridge if further away. Total outbuilding coverage must not exceed 50% of your garden. Listed buildings, conservation areas, and AONBs are exceptions where you must apply to the council. Scotland uses a 1m boundary rule instead of 2m. When in doubt, request a Lawful Development Certificate from your local authority for about £100.
-
Can I use a garden room as a home office all year?
Yes, if you choose an insulated model with double glazing. Our Calmpod insulated pods have 100mm wall insulation and U-values matching a modern house wall. They maintain 18-22°C with a small electric heater. Uninsulated log cabins (28mm walls) are comfortable from April to October but drop below 10°C in winter without significant heating. For year-round use, spend the extra on insulation. It saves £300+ per year on heating versus a single-skin building.
-
What base does a garden room need?
A 100mm concrete slab or ground screw system is required. Garden rooms are far heavier than sheds. Paving slabs on sand will shift over time, causing doors and windows to jam. We recommend a reinforced concrete base extending 50mm beyond the building footprint on all sides. Pour a cable duct through the base before the concrete sets if you plan to run electricity. Our concrete base guide covers the full process.
-
How do I get electricity and internet to a garden room?
Run Steel Wire Armoured (SWA) cable underground from your house consumer unit. Standard extension leads are not safe for permanent buildings. A Part P qualified electrician must do the connection. Budget £800-£1,500 depending on the distance from your house. For internet, run an external-grade CAT6 ethernet cable alongside the power cable. Wi-Fi struggles to penetrate insulated walls with foil-backed boards. Powerline adapters work as a fallback if your house wiring supports them.
-
What is the difference between a garden room and a summerhouse?
Insulation is the key difference. A garden room has insulated walls (50-100mm), double-glazed windows, and weatherproof EPDM roofing for year-round use. A summerhouse is a single-skin timber building (12-19mm walls) designed for warm-weather use only. Garden rooms cost more upfront but deliver a usable room 12 months of the year. If you only want a retreat for May to September, a summerhouse saves you thousands.
-
Will a garden room add value to my property?
A quality garden room can add 5-15% to your property value. Estate agents report that a well-built garden office is now a selling point in the same way a conservatory was in the 2000s. The key is quality of finish. A properly insulated room with electrical supply and double glazing adds significantly more value than an uninsulated shed with a desk in it. Around 40% of UK workers now work remotely at least part of the week, driving demand for dedicated home offices.
-
How long does delivery and installation take?
Most garden rooms are delivered within 2-6 weeks of ordering. Palmako log cabins arrive as pre-cut kits for self-assembly (2-3 people, 2-3 days). Calmpod insulated pods and Lichfield premium buildings include professional installation as an option. Self-assembly suits experienced DIYers with a helper. Professional installation typically takes 1-3 days depending on the building size and adds 15-20% to the total cost.
