Bespoke Garden Annexes Across Surrey
As families grow and living requirements change, a garden annexe is the most cost-effective way to add a high-quality, independent living space to your property. At Garden Rooms Surrey, we design and build premium, fully insulated annexes that provide the comfort of a home extension at a fraction of the cost and disruption.
Whether you are looking for a granny annexe for an elderly relative, a teenage retreat, or a luxury guest suite, our team handles the entire process—from initial design and planning advice to professional installation and internal finishes.
Versatile Uses of Garden Annexes
Granny Annexe for Elderly Relatives
A self-contained garden annexe offers the perfect balance of independence and proximity. We can design your annexe with easy-access layouts, efficient heating, and optional ensuite facilities to ensure your loved ones are comfortable, safe, and close by.
Teenage Retreat & Independent Living
Give your older children the space they need. A garden annexe provides a quiet, independent area for study and sleep, helping them stay at home longer while maintaining their own privacy (and yours!).
Luxury Guest Accommodation
Stop relying on the sofa bed. A dedicated garden guest room provides your visitors with a hotel-standard experience, complete with full insulation, double glazing, and optional plumbing for a private shower room.
Premium Specification as Standard
We don’t just build “sheds”—we build high-specification garden buildings designed for 365-day use:
- Full Insulation: 100mm wall and 150mm roof insulation for maximum thermal efficiency.

- Internal Electrics: Full lighting and socket installation tailored to your layout.

Planning Permission & Building Regulations
When building a garden annexe for sleeping accommodation, the rules are different from a standard garden office. While many projects fall under Permitted Development, an annexe often requires a closer look at Building Regulations and Planning Permission.
We handle the complexity for you. During your free site visit, we will assess your garden and advise on the most straightforward route to getting your annexe built legally and safely.
