Gethin R Haycock and his team of experienced builders and craftsmen provide a high standard of building construction work for new builds, extensions and period properties in Abergavenny and throughout Monmouthshire.
With a reputation for meticulous stonework and high standards of building, GRH are frequently hired to manage building work for listed building and historically sensitive structures. They also welcome briefs for property conversions, contemporary extensions, garden patios, driveways and hard landscaping.
GRH Building Contractors have considerable experience of new builds and preparatory structural work, including remedial construction and underpinning work, Gethin is able to project manage building contracts for both domestic and commercial constructions and can lead a team of contractors as a foreman. He also works well with an established team.
GRH Building Contractors is a highly professional company with excellent communication throughout the entire build. From the outset, they provided expert advice and presented several options to consider. We are delighted with the final result. The patio blends seamlessly with the existing wall and looks fantastic. The team worked incredibly hard and even returned afterwards to ensure everything was thoroughly cleaned up. We couldn't be happier with the outcome.

Home in Llangynidr
New build between Crickhowell and Brecon
In 2022, GRH Building Contractors were instructed to demolish a bungalow and construct a new-build home in the heart of the Welsh countryside. Set in the small village of Llangynidr, within the Brecon Beacons National Park, the site enjoys stunning views across to the Black Mountains - a truly idyllic location. Using locally sourced stone and materials, GRH combined excellent craftsmanship with years of experience to create a property that blends seamlessly into its surroundings. The result is a beautiful home that will be enjoyed for generations to come.

Single storey extension with garden transformation
GRH were commissioned to build a single storey extension to this family property to create extra living space and easy access to the garden. The project features a roof lantern in the extension and bi-fold doors leading outside. Included in the brief was a garden landscape transformation featuring cedar wood slat fencing, a porcelain tiled patio and raised flower beds.
"We were very happy with the building work GRH carried out on our cottage. Gethin was extremely helpful and he completed the work within the timescale we had agreed. We have no hesitation in recommending him."
