Garden Annexes Berkshire

Our one- and two-bedroom garden annexes give family members a self-contained place to live in Berkshire. Built with our Structural Insulated Panels (SIPs), they’re warm, efficient and quicker to install than a traditional build. You can choose from one- or two-bedroom models with options such as underfloor heating, decking and different exterior finishes.

Each project is designed to meet building regulations and is managed by our team from planning through to installation. If you prefer a DIY or main contractor route, we also supply flat-pack annexe kits across Berkshire.

Annexe Design and Planning in Berkshire

Planning a garden annexe starts with choosing the right layout, position and specification for your home. At Annexe by Future Rooms, we help homeowners across Berkshire design practical, comfortable living spaces for relatives, guests or independent family use.

Our one- and two-bedroom annexes are architecturally designed and built using pre-manufactured SIPs, helping to create a well-insulated, habitable space with faster installation and less disruption on site. Layouts can also be adapted with optional extras to suit your needs.

We can support your project with structural calculations, groundworks, planning applications and installation. Depending on your annexe, this may involve a Certificate of Lawfulness, Householder Planning Permission, or both full Planning Permission and a Certificate of Lawfulness under The Caravan Act.

From design to installation, our experienced team manages the process for you, helping you move from an initial idea to a finished garden annexe that is built for year-round use.

Bespoke School Classroom

Modular Buildings for Businesses, Schools and Clubs

We design and install SIP modular buildings for businesses, schools and sports clubs throughout Berkshire. Our buildings are used for offices, meeting rooms, reception areas, classrooms, clubhouses, changing rooms, storage and staff facilities.

Because they’re built with our SIPs, these projects go up quickly with less disruption than a traditional build. The panels provide high levels of insulation, helping to control running costs while keeping the space comfortable year-round.

We supply modular solutions for a wide range of sites, from extra teaching space at a local school to a new pavilion for a sports club or a small office building on an industrial estate. Each project is designed to suit the site and use, with a full structural design and installation service managed by our team from start to finish.

If you need more space in Berkshire, our modular commercial, leisure, sports and school buildings offer a practical alternative to conventional construction, delivered to site and installed on a schedule that works around your organisation.
