They install quicker than a standard extension, cost less and often donât need full planning permission. That means less waiting, less stress, and more space ready to use when you need it.

A granny annexe is a self-contained home built in your garden. It usually includes a bedroom, bathroom, kitchen and living space, allowing a relative to live close by while keeping their independence.
A garden lodge is a self-contained living space, often built under Caravan Act rules. It includes everything needed for independent living and is ideal for a family member or guest.
All kitchens, bathrooms and fitted furniture are part of our standard build. There are no hidden charges.
Thereâs no fixed size, but we recommend at least 30â35 square metres of usable garden space for a one-bedroom annexe. We offer a free site survey to assess what will work best in your garden.
