Annexe Spaces - Contemporary Bespoke Living

Annexe Spaces provide stunning, contemporary living spaces offering premium quality, bespoke buildings without the hefty price tag.

All our buildings are made to order, so we maintain maximum flexibility in terms of creating a design that suits our client's needs and budget. We run a very lean business with no warehousing or expensive showrooms - which our competitors will likely need to charge for.

We design and install buildings across most of England, and also parts of Wales but mainly focus our attentions on the Home Counties and London/around and inside the M25.

We'd love to discuss how we can help with your project whether you are looking for self contained living, an additional bedroom or even a compact multifunctional space.
