The OSO Arts Centre is a 130-seat theatre located in Barnes in the London Borough of Richmond upon Thames. The building was previously Barnes' postal sorting office, but was redeveloped into a mixture of residential and commercial space with the first residents arriving in 1999. In 2002 the arts centre opened and in 2012 the OSO Arts Centre came under the direction of a new board of trustees. The building is located on Barnes Green, and provides arts services to the community, both in the form of evening performances in the theatre space, and daytime dance and art classes. Some well-known names have performed at the OSO over the years including Patricia Hodge, Timothy West, Stephanie Cole, Julian Glover, Janie Dee, Issy van Randwyck, Harriet Thorpe, Lee Nelson and Robert Pattinson.
