Granny Annexe is one of the most forward-looking and experienced garden building companies in the UK, completing hundreds of builds across England and Wales.

Initially starting-up in 2007 as a family business, we have maintained our family-centric approach to all our products. We put your family’s needs at the heart of what we do, so you have a smooth and easy experience throughout your Granny Annexe build.

We’ll build your Granny Annexe to the highest standard, complying with the latest set of Building Regulations in England and Wales. We also manufacture our own Structurally Insulated Panel Systems (SIPS) for each build, so you’ll benefit from the high quality insulating properties in all seasons.

We provide a full turnkey service from start to finish. Our professional staff will support and guide you, handling everything throughout the process from the initial site survey to when you receive your keys. At Granny Annexe, we also create and submit your planning application, provide complete project management throughout the build and ensure your liveable Granny Annexe is fully connected to utilities and drainage.

Then, all you have to do is move in . . .

It’s been a very positive experience dealing with you . . . Your company has been professional efficient and caring.  If I had another opportunity I would choose your company all over again. “

Namrata, Surrey

The building team were amazing! I’m sure you get this a lot, but we genuinely can’t speak highly enough of them. ..”

Claire B, Cheshire

From start to finish of the process I have found your company a joy to deal with. Everything has been really professionally handled, the teams of workers have been polite, hard-working and good at what they do. Also a great feeling of pride in their work as well

Charles T, Sussex

“I am not sure that your chaps are human. I think they are giant worker ants disguised as humans. They have a phenomenal work rate.”
