  • 3m Single Story Rear Extension

    GT Building Services were great from start to finish. A pleasure to have working on our 3m single storey kitchen extension. We weren't initially intending to have a timber frame extension but so glad we got GT building services round to quote and work on our extension, I wouldn't build any other way after seeing how reasonable the quote was and how tidy and quick the build was. Tristan and his team were on time every day and worked hard into the evenings to keep the build on programme, they project managed and brought in relevant trades, electrician, plumbers etc, all were great. They coordinated structural calcs, drawings and site visits with the building inspector and they were pleased with all the work done, no issues. Tristan left the house and site tidy every single day and were always on hand to answer any questions or queries if needed. We have since recommended GT building services to several people and they are all equally impressed. Will 100% use again, can't recommend enough.

  • Internal garage conversion

    Lovely guys, really pleased with their work. Would highly recommend and use again.

  • Kitchen knock through into garage and re-fit

    We cannot praise GT Build highly enough. We hired Gareth & Tristan from GT Build to knock from our existing kitchen through to the garage to make a big kitchen-family room. The job involved knocking down &reinforcing the wall, fitting bi-folding doors & a new window, taking out the old kitchen & fitting a new one inc brickwork, building a small utility room with sink & cabinets, fitting a new garage door, installing new floors, electrics, & plumbing throughout, & finally designing & building a bespoke wall-to-wall, floor-to-ceiling bookcase. We are over the moon with the results! Their attention to detail & pride in their work is second to none and they are incredibly hard grafters - here from 7am to 6pm or even 8pm everyday (including weekends)! The work is such a high standard and beautifully finished - we can't wait to show it off! They were friendly, professional, down-to-earth, put us at ease, and solved plenty of unforeseen issues without passing any of the stress onto us. We were kept in the loop the whole time & offered solutions rather than problems. They were honest about pricing & everything was left so clean & tidy. To be honest, we are going to miss having them around the house! We would hire them again in a heartbeat & would recommend them to everyone.
