The Rayne Building is a 4-storey accommodation block on the main College site. The building is an excellent example of 1960s architecture found in Cambridge. It is incorporated into the main college structure, between Newnham Grange and the Hermitage.
Some of the Rayne Building rooms overlook a secluded part of the River Cam which runs through the College grounds. Other rooms face Silver Street and have prominent views of Queens' Green.
The first and second floors of the Rayne Building have, respectively, ten and eleven rooms with shared facilities: two shower rooms, two toilets and a large kitchen. The third floor has four rooms (each with shower); two toilets; and a shared kitchen. There are also two guest rooms situated on the top floor, available to book for all Darwin members and their guests.
