Construction is due to start next month on a £7.3m extension to the Belgrade Theatre in Coventry designed by architect Stanton Williams. The work will improve the 1950s theatre by adding a 300-seater auditorium, rehearsal space and a foyer. A contractor is being chosen this week from a shortlist. The team was Davis Langdon as QS, Flint and Neill as structural engineer, Rybka as M&E contractor, Arup Acoustics as acoustic engineer, Theatreplan as theatre consultant and Buro 4 as project manager.
