Caruso St John was established by Adam Caruso and Peter St John in 1990. The practice gained an international reputation for the New Art Gallery in Walsall which opened to wide public acclaim in 2000. Since the completion of the New Art Gallery, the practice has worked for many institutional and private clients in the field of museums and galleries. They have worked for the Victoria & Albert Museum on the restructuring and extension of the Museum of Childhood in London. In 2004 they completed the Gagosian Gallery in Britannia Street, London, and have subsequently designed the gallery's spaces in Davies Street, London, and Via Crispi, Rome. The practice is currently on site with the new Centre for Contemporary Art in Nottingham that will open at the beginning of 2009. At the beginning of 2007, Caruso St John was appointed architects for Tate Britain.
