The very helpful fellas at Huws Gray can take a set of architects drawings and calculate what materials are required removing the guess work for you. They offer one of the largest ranges of materials in the area and are happy to attempt to price match the major builders chains. Often they are able to suggest an alternative product to the one you’re seeking at a much more reasonable price. If they don’t have it in stock they’ll order it in no matter how bizarre your request. Best of all delivery is free too and the delivery drivers are extremely accurate with their drops no matter how challenging your location.
