About GTA Builders, Property Extensions in Ystrad Mynach
A local building firm established in 1995, with over 30 years in the trade.
A Building Firm Based in Ystrad Mynach
GTA Builders has been working since 1995 and is based in Ystrad Mynach, in the heart of Caerphilly county. Gareth Thorp is the person to speak to about your project.
The work covers most of what a home can need: property extensions, conversions, new builds, renovations, kitchens, bathrooms, roofing and the garden outside. Having that under one firm means fewer trades to organise on a bigger job.
Friendly, straightforward communication matters as much as the building itself, from the first quote to the last day on site.
