Garden Living Annexes

Creating additional accommodation space can unlock real value since investment costs are typically more than repaid by an increase in the overall house price.

We offer different sizes and styles of garden annexes to suit all gardens; simply choose the building on its own or we can offer a full turnkey solution to include the kitchen and bathroom.

Garden Annexe B&B

When Rose told us about her vision of creating a holiday let business, we couldn’t wait to help. Like her, we could see the earning potential of inviting paying guests to enjoy the beautiful countryside surrounding her Welsh home. 

All that gorgeous land, and the breathtaking views of rolling hills and valleys, but Rose didn’t have any spare indoor space to accommodate guests.

The solution? One of our beautifully crafted Living Log Cabin Garden Annexes. A stand-alone building would make an idyllic countryside hub for guests to enjoy nature, go on countryside walks and bike rides, or just relax and soak in the views.

Sustainable Garden Annexe Construction

For over 20 years we’ve been a leading supplier and installer of environmentally friendly garden buildings.

Our Garden Annexes are made from sustainable timber, certified by PEFC (Program of the Endorsement of Forest Certification) or FSC (Forest Stewardship Council)
