Premium Builders in Chelmsford
Award-winning construction, heritage restoration and bespoke extensions across Chelmsford and surrounding areas.
Building in Chelmsford
As our home base since 1987, Chelmsford is where Hartwell & Stone began and where our reputation was forged. From Victorian terrace renovations in the city centre to contemporary new builds in the surrounding villages of Writtle, Great Baddow and Galleywood, we know this city intimately — its conservation areas, its planning quirks, and its discerning homeowners.
Our Chelmsford projects benefit from the shortest lead times and the most competitive pricing in our portfolio, thanks to minimal travel overheads and deep relationships with local suppliers, planning officers and building inspectors. Whether you're extending a 1930s semi in Springfield or restoring a listed farmhouse in Broomfield, our team is never more than ten minutes away.
