Two-Storey Extensions
Maximise your home's potential with a two-storey extension adding bedrooms and living space.
About Our Two-Storey Extensions Service
A two-storey (or double-storey) extension is the ultimate way to add capacity—typically providing extra bedrooms, bathrooms, and enlarged living areas. It requires robust structural design, usually involving steel beams or RSJs to support the additional weight. Our architects and surveyors calculate load-bearing requirements, manage Building Regulations, coordinate planning permission, and oversee the entire build from foundations through to roof and interior fit-out. We pay meticulous attention to party wall matters if you're near a boundary.

Two-Storey Extensions — Frequently Asked Questions
Yes, two-storey extensions typically require steel beams (RSJs) to carry the load of the upper floor and roof. A structural engineer calculates the exact specifications. Steel is then encased and hidden within the construction—you won't see it in the finished space.
If your extension is near a neighbouring property's boundary, the Party Wall Act usually applies. We manage all necessary notices, surveys, and agreements with neighbours to keep the process smooth and compliant.
Build duration depends on size, ground conditions, and complexity. Ask for realistic timescales when you request a quote.
