Looking for a permanent living solution?

We have developed a range of buildings that can be used as a permanent living solution called The Annex. These buildings may look a little bit like the Green Retreats garden buildings but are actually made entirely differently to be a ‘proper’ house. The Annex buildings comply with building regulations and are signed off by building control. They also come complete with kitchens and bathrooms as well as plumbing.
