The centre of the site was redeveloped to Arup's plan in 1966–71, with the loss of most of the original buildings by Salvin to accommodate the Arup Building (now the David Attenborough Building), accommodating zoology and metallurgy. In 1974, the Cavendish Laboratory moved to a new science site to the west of the city, now known as West Cambridge.
