The RIBA's headquarters has been at
66 Portland Place, London, since 1934. This Grade II*
listed building was designed by architect
George Grey Wornum for the institute and features sculptures by
Edward Bainbridge Copnall and
James Woodford. The building is open to the public, and includes a library, architectural bookshop, a café, bar, exhibition galleries and lecture theatre. Rooms are hired out for events. The organisation also owned an adjacent building at 76 Portland Place, a 1950s office building overhauled in 2013, which housed RIBA staff and a members' café. In September 2021, following the
COVID-19 pandemic and an £8 million budget deficit in the year ending December 2020, the RIBA announced plans to sell 76 Portland Place and to reduce staff numbers. Chief executive Alan Vallance said 89% of the RIBA's staff only wanted to work two or three days a week from an office, so 76 Portland Place was surplus to requirements. A potential 20 further redundancies were reported on 31 January 2022. The organisation's annual report and accounts for the year ending 31 December 2022 reported a £6.3 million trading deficit (following shortfalls of £8 million in 2021 and £8.2 million in 2020), though the sale of its lease on 76 Portland Place for nearly £12 million had since helped balance its books. In January 2022, the RIBA announced an architectural competition for RIBA-chartered architectural practices for a £20 million+ "comprehensive refurbishment" of its 66 Portland Place. In 2024, this renovation was budgeted at £85 million. The building will close on 1 June 2025 for two and a half years to enable refurbishment. In March 2025, the RIBA said staff would be temporarily relocated to the
Royal College of Physicians' Jerwood Centre during the work, but this decision was withdrawn in May 2025. In August 2025, the RIBA said staff would instead be housed in the central London offices of the
British Medical Association in
Tavistock Square.
British Architectural Library The British Architectural Library, sometimes referred to as the RIBA Library, was established in 1834 upon the founding of the institute with donations from members. Now, with over four million items, it is one of the three largest architectural libraries in the world and the largest in Europe. Some items from the collections are on permanent display at the
Victoria and Albert Museum (V&A) in the V&A + RIBA Architecture Gallery and included in temporary exhibitions at the RIBA and across Europe and North America. Its collections include: •
Archives: 1.5 million items made up of architects' personal papers, correspondence, notebooks and diaries. •
Audiovisual materials: Talks held at the RIBA, including talks by winners of the Royal Gold Medal. •
Biographical files: 20,000 biographical files relating to a specific architect or firm. Files contain a mix of nomination papers for membership of the RIBA, obituaries, brochures, articles and letters. •
Books: 150,000 books and 20,000 pamphlets, with the earliest book dating from 1478. Amongst the items is a first edition of
Andrea Palladio's ''I quattro libri dell'architettura'' from 1570 and
John Tallis's ''Tallis's London street views'' from 1838 to 1840. •
Drawings: 1 million items are held. These predominantly cover British architects from the Renaissance to the present day, such as
Ernő Goldfinger,
Charles Holden and
Edwin Lutyens. It holds the world's largest collection of drawings by Andrea Palladio. •
Models: Examples come from architects such as
Denys Lasdun for his Keeling House and National Theatre, London. •
Periodicals: 2,000 architectural titles collected, with complete sets of
Architectural Review, ''
Architects' Journal, and Country Life''. •
Photographs: 1.5 million items, including the archive of the Architectural Press. Items date from the 19th century, but with major holdings of 20th-century photographers such as
Eric de Maré,
John Maltby, John Donat and Henk Snoek. The overcrowded conditions of the library was one of the reasons why the RIBA moved from 9 Conduit Street (where it had been since 1859) to larger premises at 66 Portland Place in 1934. The library remained open throughout
World War II and was able to shelter the archives of Modernist architect
Adolf Loos during the war. The library is based at two public sites: the Reading Room at the RIBA's headquarters, 66 Portland Place, London; and the RIBA Architecture Study Rooms in the Henry Cole Wing of the V&A. The Reading Room, designed by the building's architect George Grey Wornum and his wife Miriam, retains its original 1934 Art Deco interior with open bookshelves, original furniture and double-height central space. The study rooms, opened in 2004, were designed by
Wright & Wright Architects. The library is funded entirely by the RIBA but it is open to the public without charge. It operates a free learning programme aimed at students, education groups and families, and an information service for RIBA members and the public through the RIBA Information Centre. A partnership with the
London Archives will see some of the collections and contents of the library transferred temporarily to the London Archives,
Clerkenwell, when the library closes in April 2025 for the renovation of 66 Portland Place.
V&A + RIBA Architecture Partnership Since 2004, through the V&A + RIBA Architecture Partnership, the RIBA and
V&A have worked together to promote the understanding and enjoyment of architecture. In 2004, the two institutions created the Architecture Gallery (Room 128) at the V&A showing artefacts from the collections of both institutions, this was the first permanent gallery devoted to architecture in the UK. The adjacent Architecture Exhibition Space (Room 128a) is used for temporary displays related to architecture. Both spaces were designed by
Gareth Hoskins Architects. At the same time the RIBA Library Drawing and Archives Collections moved from 21 Portman Place to new facilities in the Henry Cole Wing at the V&A. Under the Partnership new study rooms were opened where members of the public could view items from the RIBA and V&A architectural collections under the supervision of curatorial staff. These and the nearby education room were designed by Wright & Wright Architects. In June 2022, the RIBA announced it would be terminating its partnership with the V&A in 2027, "by mutual agreement", ending the permanent architecture gallery at the museum. Artefacts will be transferred back to the RIBA's existing collections, with some rehoused at the institute's headquarters at 66 Portland Place, set to become a new House of Architecture following a £20 million refurbishment. In January 2026, the RIBA signed a deal to move the four million items in its historic drawings and archives collection to the
National Archives in
Kew while plans for a more permanent home were finalised. The RIBA Study Room at the V&A will close in June 2026, but will then close while the collection is transferred to Kew, where a new study space will be available from autumn 2027. ==RIBA Awards==
