House Extensions — Where We Work

Precision-engineered modular house extensions, built nationwide.
Every Vita Modular extension is 100% bespoke and fully customisable, with planning and building control approved and managed for you, fast off-site construction and a fixed, all-inclusive price.

We build house extensions right across the UK

Because every Vita Modular extension is engineered off-site in our factory and installed as a near-complete structure, we're not tied to a single region. Wherever you are, you get the same fixed price, the same managed process, and the same 10-year warranty.

We operate nationwide

From inner-city terraces to rural family homes, our modular extension system travels to you — delivering factory precision on site, wherever “site” happens to be.
