Double Storey Extensions

A two-storey extension is the most cost-effective way to add serious space — extra living space downstairs and a bedroom, bathroom or master suite above. Because the roof and foundations are shared across two floors, you get more room per pound than a single-storey build.

Extra ground-floor living space and a room above
Matched brickwork and roofline to the existing house

Double Storey Extensions — frequently asked questions

Is a double-storey extension better value than single-storey?

Usually yes — sharing foundations and roof across two floors gives more space per pound. We can price both so you can compare.

Will a two-storey extension need planning permission?

Two-storey extensions more often need planning than single-storey. We assess it and manage the application for you.

Can you match the existing brick and roof tiles?

Yes — we source matching or closely sympathetic materials so the extension reads as part of the original house.

How long does a double-storey extension take?

Typically 12–20 weeks on site depending on size and finish. Your programme is set out in the quote.
