The Royal Institute of British Architects is a professional membership organisation and aims to advance architecture by demonstrating benefit to society and promoting excellence in the profession.
The organisation's HQ is in a fine Grade II-listed 1930s building, designed by Grey Wornum, at the junction of Portland Place and Weymouth Street in London W1.
The building houses an extensive architecture bookshop, a café with outdoor terrace, galleries hosting exhibitions, lecture theatres for talks, and is home to one of the finest architectural libraries in the world.
