Double the space. One project.

Double-storey extensions maximise your investment — adding living space on the ground floor and bedroom or bathroom space above, with a single planning application and build programme.

What we deliver.

A double-storey extension is one of the most cost-effective ways to add significant space to a home. Because much of the structural and planning work is shared across both storeys, the cost per square metre is lower than two separate single-storey projects. We manage the entire process — architecture, structural engineering, planning application, building regulations and full construction — under one contract.
