Our Garden Rooms are the most versatile structure we build — equally at home as an entertainment space, a creative studio, a home bar, or simply your favourite room in the house. They come with grand aluminium bifold doors, a canopy with LED lighting, and a premium cladding finish as standard. These are rooms designed to be used and enjoyed, not just looked at.

Whatever You Want It to Be
The beauty of a garden room with bifold doors is that it blurs the line between indoors and outdoors. Open them up on a summer evening and you have an extension of your garden. Close them on a January afternoon and you have a warm, insulated, light-filled room with nowhere else quite like it.

Most Garden Rooms Don't Need Planning Permission
Under Permitted Development rights, most garden rooms can be built without planning permission. The rules cover footprint, height and position — and the large majority of standard builds fall comfortably within them.
We confirm your permitted development position at the free site visit. If there's any doubt, we'll discuss obtaining a Certificate of Lawful Development to give you total certainty before we start.

"We had a cinema room and home office designed and built. We have been using it for over a year now and still love it. The quality is exceptional and the workmanship is stunning. Very pleased we went with The Green Rooms!"
"The garden room was exceptional during the hot summer months. It remained cool and comfortable without any air conditioning, which was a pleasant surprise. James is a true professional and craftsman."

Frequently Asked Questions
More questions? See our full FAQ →
What's the difference between a garden room and a conservatory?
A garden room is a fully insulated, year-round structure with its own electrical installation — built to the same standard as a house extension. A conservatory is primarily glazed, loses heat in winter and overheats in summer, and typically has planning restrictions of its own. A garden room costs less than a full extension, doesn't require party wall agreements, and is usually built under Permitted Development. It adds more usable space per pound spent.
Does a garden room need planning permission?
Most garden rooms fall under Permitted Development — no planning permission required. The rules cover footprint (no more than 50% of the garden), height (single storey, max 2.5m within 2m of a boundary), and position (not forward of the principal elevation). Listed buildings and conservation areas may require consent. We confirm your position at the free site visit — and if there's any doubt, we'll advise on obtaining a Certificate of Lawful Development.
Is a garden room worth the investment?
In almost every case, yes. A well-built garden room adds 5–15% to property value — often significantly more than the construction cost. Beyond the financial return, it transforms how you use your home: a separate space for work, hobbies, fitness or entertaining that doesn't consume indoor rooms. Many of our customers tell us it's the best money they've spent on the house. See our reviews for first-hand accounts.
Can I use a garden room all year round?
SIPs construction gives you genuine year-round insulation — the same panel system used in Passivhaus buildings. With a smart panel heater (or air conditioning for summer cooling), a garden room is comfortable in every season. Every garden room in our standard range is designed and built to the same year-round specification — there's no 'summer use only' version.
Can a garden room be used as a guest bedroom?
Yes, many of our customers use their garden room as overflow guest accommodation. We'd recommend sizing to at least 4×3m for a comfortable bedroom with a seating area. You'll also want to consider: a toilet or shower room (we can include a WC in a bespoke build), window blinds or curtains for privacy, and heating that can be set on a timer. For a dedicated annexe with sleeping accommodation, see our bespoke options.
How does a garden room compare to a summer house?
A summer house is typically a thin-walled timber structure with minimal insulation — suitable for a few months a year. Our garden rooms are built with SIPs panels, A-rated glazing, and a full electrical installation. They're insulated to a higher standard than many brick-and-mortar extensions, and are designed to be used every day of the year. The price difference reflects the quality difference.
What Makes Us Stand Out
Every Green Rooms build uses the same premium specification — regardless of price point.
Full ComparisonSIPs Construction

20-Year Roof Guarantee
EPDM or metal panel on every build — never felt. Both carry a 20-year guarantee as standard.
Fully Turnkey Service
Foundations, structure, cladding, glazing, electrics, flooring, plastering, and site clean-up all included. We hand the keys over on the last day — you walk into a finished room.
