Client Testimonial

“It’s always nice to see H+H products and solutions being used with sustainability at the forefront. Oyster Reach is a beautiful development and is unique in its approach to the environment. The Thin-Joint System is easy to use and promotes the use of larger blocks, such as Jumbo Blocks, with 2mm joints rather than the traditional 10mm joint. This enables a building to be built faster whilst reducing cost and waste on site.”

John Churchett, H+H
