Consisting of Supplying, Installing, and Manufacturing. The contract was to fix 51 stones which were 1000mm x 800mm and 40mm thick to the outside of 151 Wardour Street between fifth and sixth floors. The building was listed and the new material was to be a match as close as the existing. The stones were fabricated to achieve a bookmatch pattern (the viens in the Onyx joined to form their natural pattern). This made this project longer than a normal project as every piece cut from a slab had to be match and labelled. All stone were fixed using stainless steal hidden fixings. The joints were finished with a waterproof silicone. The stones were fixed within three weeks.
