Work to the Prince of Wales Theatre includes a transparent facade, a redesigned auditorium and renovation of the bar and backstage areas. Work costing an estimated £7m is due to start in the next few weeks.
Devon-based WFC will also oversee the expansion of the auditorium and the dress circle bar at the Strand Theatre. It is due for completion next year.
The Wyndhams and the Albery theatres will benefit from renovation work due to start in September 2005.
