Annexes

Designed for living. Built for life.

Garden annexes, also known as a granny flat, is a self-contained living space. Garden annexes are a popular and cost-effective way you can create additional living areas, whether this is needed for extended family members, older children, overnight guests or even as an Airbnb.

If you can imagine it, we can build it – even if you already have plans, we can work from them to help your idea come to life. Take a look at our designs below. Each one has its own unique character and can be edited to suit your unique requirements and space.

Why choose a garden annexe over a garden room?

If you have the space and the need for a garden annexe, they can provide you with so much more flexibility – and creativity – than a garden room. Here’s just some of the benefits…

A habitable living area

An annexe is a habitable living space, meaning it can include a kitchen, multiple bedrooms, and bathrooms for complete comfort.

Enjoy having more room

Annexes are a great way to utilise your outdoor space, whilst giving you more space inside your home. Design your annexe to use as much space as possible!

A multi-use space

Whether it’s to be lived in, used as a guest house or Airbnb or maybe it’s simply an extension of your home – annexes are multi-use spaces.

Planning Permission

Unlike a garden room, you do require planning permission before you have an annexe installed. This means more extensive planning and prep work is required, but we can guide you through this process and make it as simple as possible.
