The private building firm also said chief sustainability officer Julia Barrett was being promoted to the board as director responsible for sustainability and non-financial compliance.  

Group chief executive Rick Willmott said: “I’m delighted to welcome both Julia and Juliette to the Board.

“Julia’s promotion is recognition for her work shaping our sustainability strategy and driving forward our zero-carbon commitments, which has seen a 68% reduction in carbon emissions (relative to turnover) since 2010.

“Likewise, Juliette, who will chair our Audit Committee when Christopher Sheridan retires, brings a wealth of experience from senior positions both within and outside our industry and her financial and technical knowledge will greatly complement our existing depth of experience.”

These are the latest board appointments; in July this year, the company announced that Julie Hirigoyen, Chief Executive at UK Green Building Council, was joining as a NED.
