What could a garden room mean to you and your family?

For peace, space and somewhere to just be.

That might mean a home office, a gym or a place to entertain. The choice is yours, along with where it’s going to be, what it will look like and when in the day you’d like the sun to come pouring through the windows. Because it will.

They’re built to last. So long in fact that your children’s children will be able to enjoy it, because they’re made of sturdy steel with aluminum cladding as opposed to wood, which simply wont last as long.

Why choose a garden room?

Unlike any other that we are aware of, the high spec of our designs mean that you can use our garden rooms as a direct extension to your house, should you choose. Being made from steel and aluminium means that the spaces are incredibly durable and long-lasting, making them an ideal investment for your property.

Much less complicated than a traditional home-extension, if you want extra space that can be put up in a matter of weeks, rather than months, then this might just be the perfect option for you.

Garden Rooms – the ultimate space-solution

Whilst there is, of course, a core system to our garden rooms, they are fully configurable, meaning that we take the modular system and turn it into any kind of space you desire. With a new focus on working from home, entertaining and home and holidaying at home, there’s never been a better time than to create some of these amazing spaces in your own home or, of course, your own garden.

And just because it’s in your garden, doesn’t mean it can’t come with all your creature comforts. Any amenities that you have in your home can be installed in your garden room, whether WiFi, AC, heating, plumbing, electrics, gas and more.
