Our People

As with any trade or service industry, we are only as good as the people who work for us. CWO is therefore fully committed to training, not only for the masons on site and in our workshop who form the backbone of our orgainisation, but for every single person within the business from management to administration. This commitment is reflected in the quality of work carried out by CWO, the projects we have carried out and the awards we have received.

  • Malcolm Diamond MBE, Chairman

    Malcolm joined CWO in May 2004 as Chairman, having been recruited by the Osborne Group to help grow the business. By 2006, the CWO management team was in a position to negotiate an MBO which was completed in October 2006, and the Company has since nearly doubled in size over the past three years.

    Malcolm is also Chairman of Trifast Plc, senior NED of Dechra Pharmaceuticals Plc, NED of Unicorn VCT 11 Plc investment fund, and a partner in Soundscape Environmental Structures LLP.

    “I can honestly say that amongst all the companies I have worked with over the years, the CWO team have given me the confidence and motivation to support their quest to be widely acknowledged as the best in the UK Stone construction and renovation / conservation sector for as long as I can personally add value to their growth.”
