Is it cheaper than a house extension?

Significantly. A single-storey extension typically costs £30,000-£60,000 and takes months. A garden room starts at £12,500 fully installed and is done in about a week. It's not even close.

Can the kids use it as a playroom year-round?

Absolutely. It's properly insulated and heated, so it's comfortable in every season. A lot of our customers use it exactly for this. Keeps the toys out of the living room too.

What flooring can I put in?

We provide a flooring-ready subfloor, so you can fit whatever you like: laminate, vinyl, carpet, engineered wood. Most people choose something hard-wearing and easy to clean.

Will it add value to my house?

A properly built garden room typically adds value, yes. Estate agents increasingly list them as a selling point. It's usable space that buyers appreciate.

Can I put a TV and sofa in there?

Of course. The electrical package includes plenty of sockets, and the room is insulated and lined like a proper living space. Big screen, surround sound, the lot. It's your room.

What you get

What's included

Sometimes you just need more room. Maybe the kids have taken over the living room, the dining table's permanently covered in homework, or you'd love a quiet spot to sit and read without the telly on. A garden room gives you that extra space without the disruption, cost, and hassle of a full house extension.

Our Garden Room is designed as proper living space. It's insulated to the same standard as our offices, so it's warm in winter and comfortable in summer. Big glazed doors let the light flood in and open up the view to the garden, which makes the room feel a lot bigger than the square metres suggest. It's a genuinely nice place to spend time.

People use them for all sorts: a playroom for the kids, an entertaining space for friends and family, a quiet reading room, a spot for movie nights, or just somewhere to sit with a cup of tea away from the chaos. Some customers use them as a dining room when they have people over. The flexibility is the whole point.

And because it's a garden room rather than an extension, you usually don't need planning permission, you're not living in a building site for months, and the price is straightforward. Fixed quote, fully installed, no hidden extras. We'll have it sorted in 5-7 working days.
