Insulated garden rooms

Cheaper than an extension, easier than moving, an insulated garden room is a fantastic solution for your space issues.

Whether it's a home office, a garden den, gym or relaxation space, there's a Waltons building to fit your needs. Choose your size, doors and windows, and plan how you'll use the extra space in your home.

Double glazed, fully insulated and customisable to your own requirements - you decide where doors and windows go (and even how many doors and windows you have). Your garden building is delivered and installed in your garden free of charge, leaving you with time to think about how you want to use your new space.

All of our garden rooms have a high-quality, contemporary finish. You'll have a building that's practical and easily decorated to your own style and taste.

Planning permission isn't usually necessary with these buildings as they're under 2.5 metres, but it's always worth checking with your local planning department just in case there are special restrictions in your area.
