​

What Is a Garden Annex?

A garden annex is a self-contained living space located within your property's grounds. More than just a garden room, an annex includes essentials such as a kitchen, bathroom, and bedroom. It offers an ideal solution for multi-generational living, independent housing, or even passive income through short-term rentals.

At Urban Spaces, we design and build modular annexes that are fully tailored to your needs. Every project is bespoke—from the layout and size to the materials and internal finishes—ensuring your annex is perfectly suited to your lifestyle and property.

​

Why Choose an Urban Spaces Annex?

✔ Fully Bespoke Design – We don’t do one-size-fits-all. Your annex is custom-built to suit your space, preferences, and usage requirements. Whether you're after sleek contemporary design or a more traditional aesthetic, we work with you from concept to completion.

✔ Turnkey Service – We manage every aspect of the build, including planning applications, site prep, construction, and interior fit-out. No third-party contractors. No stress.

✔ Thermally Efficient & Sustainable – All our annexes are built with eco-conscious materials, ensuring exceptional energy performance, low running costs, and minimal environmental impact.

✔ Smart Home Integration – From underfloor heating to app-controlled lighting and security, we can incorporate the latest smart home tech for modern, connected living.

✔ Planning Support – Many annexes require planning permission. Our in-house experts handle all paperwork and liaise with your local authority to streamline the process.
