The headquarters of the Royal Institute of British Architects in Portland Place was erected in 1934 to the designs of George Grey Wornum, the winner of a major architectural competition. It is a classic example of an early 1930s building, commissioned by architects for architects, and is a perfect compromise between classicism and the prevailing modernism. The simple exterior derives from Swedish models. The open interior exemplifies the most up-to-date contemporary ideas about internal planning, while the rich internal finishes, worked by a team of young artist-craftsmen, recalls the English Arts and Crafts tradition. Although some enlargements were made in the 1950s, the original building survives virtually intact. It contains halls, committee rooms and offices, a bookshop and the National Architectural Library.
AHP, in association with Julian Harrap Architects, prepared a conservation management plan for the building, which is now used much more intensively than was originally intended.
