When creating additional living space for a loved one, both home extensions and garden annexes have their advantages. However, a garden annexe often provides a more flexible and independent solution.
Unlike a traditional extension, which adds living space directly onto your home, a garden annexe creates a separate, self-contained unit within your garden. This allows family members to maintain their privacy and independence while remaining close by for support when needed.
In addition, garden annexes can often be installed more quickly and cost-effectively than conventional extensions. Planning requirements may also be simpler in some cases, helping to reduce delays and streamline the overall process. As a result, you can benefit from additional living space sooner, with less disruption to your daily life and greater peace of mind.
We design and install bespoke granny annexes, garden lodges, offices, hobby rooms and garden rooms. All are made to order and tailored to your space and needs.
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 constructed 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.
There’s no fixed size, but we recommend at least 30–35 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.
