Annexe by Future Rooms supplies granny annexes and modular buildings across London for homes, businesses, schools and organisations.
If you need a self-contained space for a family member without moving house, our one- and two-bedroom granny annexes are designed as proper living spaces, with layouts and finishes chosen to suit your garden.
Built using our pre-manufactured SIPs system, they’re designed for year-round comfort and a tidy on-site programme, with optional extras such as underfloor heating and decking.
Whether you need extra room for a workplace, a school or a public-facing facility, our modular buildings are a practical way to add space in London without a long on-site build.
We design and manufacture buildings for a wide range of uses, including:
Our buildings are made using Structural Insulated Panels (SIPs) for strong thermal performance and predictable installation. Each project is tailored to the site and intended use, with our team managing the process through to delivery and installation.
