In 1922, under the ownership of managing director Sir Alfred Butt, the theatre underwent its last major interior renovation of the 20th century. At a cost of £150,000, it became a four-tiered theatre able to seat just over 2,000 people. It was decorated with one of the most notable interiors produced by the specialist ornamental plasterwork company of Clark and Fenn. Composer and performer Ivor Novello, immensely popular in his time though little-remembered today, presented his musicals in Drury Lane from 1931 to 1939.
