"This building makes a fabulous home office. We've had electricity installed and my desk and office furniture fits perfectly. The building is very substantial and the wood looks superb. The windows and doors seem to be really well built."

3m wide insulated garden rooms

A 3m wide insulated garden room can give you the extra space you really need.

Home office? Garden den? Studio or teenage hangout? These buildings are the perfect solution. They're built for year-round use - and you can get mains electricity installed by a professional quickly and easily

Free delivery and installation take the headache out of buying a garden room, and you can even customise where doors and windows go (and even how many doors and windows you have).

Double glazed, fully insulated and adaptable 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.

Designed with a high-quality, contemporary finish, you'll have a building that's practical and easily decorated to your own taste and style.

Planning permission isn't normally required with these buildings as they're under 2.5 metres, but always check with your local planning department, just in case there are special restrictions in your area.
