Extensions · Renovations · New Builds
Since 2008 we've built extensions, renovations and new homes across Gloucestershire and the Cotswolds, each one run on site by one of our own employed site foremen.
Kitchen-diners, oak-frame rear extensions, two-storey additions, loft conversions and full renovations.
Individual homes and small developments, typically one to six houses, with the option of a 10-year Build Assure structural warranty.
We stand behind our work and stay contactable after completion. Established since 2008 and still here after handover.
Steel-frame buildings, industrial units, warehouses and commercial new builds, under our trading name Thorn Construction.

New Builds · Cheltenham
This award-winning development involved the acquisition of a site containing three existing garages, which were demolished to make way for a bespoke five-bedroom detached house with a full basement. Built to achieve a net-zero carbon footprint using air-source heat pumps, heat recovery, solar panels, water-restriction devices and upgraded cavity wall insulation. It has an Ashlar stone facade over four storeys and an oak and glass staircase designed to usher in natural light.

The design features Crittall-style doors, bi-fold doors, a roof lantern and a balcony to create light-filled, open-plan living spaces.

Meet Our Founder
Trevor started out as a young roofer in his early twenties, with little more than a van and his tools. Through reputation and repeat business that grew into Thorn Homes. Over 20 years later he has overseen 450 home extensions and 55 new-build houses, and has served on the Federation of Master Builders' regional and national boards.
"I never set out to build a big construction company. I simply wanted to do a good job, look after my customers and build something I could be proud of."
