Why Families Choose Our Granny Annexes

  • The cost of a granny annexe depends on size, layout, specification, and site conditions. As a guide, most projects fall within a clear, fixed price range that includes installation, bathroom, kitchen, and internal finishes. We provide a full quotation after assessing your garden so there are no surprises.

  • Yes. All of our granny annexes are designed to be fully self-contained, with their own kitchen, bathroom, living space, and bedroom. This allows your loved one to live independently, while still being close to family.
