What it is
House Extensions, properly explained.
An extension is the biggest investment most homeowners ever make in their property. We project-manage the whole thing — coordinating a trusted architectural partner and structural engineer, then handling building control, foundations, steels, brickwork, roof, windows, plastering, flooring and decoration in-house — on one fixed price with one point of contact. No managing six separate trades, no chasing inspections, no surprise extras. Free initial visit, written quote within 5 working days, daily WhatsApp progress updates throughout the build. (Architectural drawings are produced by a vetted local practice we work with — priced into your quote and commissioned once the project is confirmed and the design deposit is in.)
