In 1964, work began on the campus facilities in the grounds of Heslington Hall. The marshy land was drained, the winding lake which dominates the campus was built, and the area was landscaped. The original buildings were designed by architects Sir Andrew Derbyshire and Stirrat Johnson-Marshall, with input also from the Vice-Chancellor Lord James, Professor Patrick Nuttgens[35][36] and the Registrar John West-Taylor.[37] The new structures were assembled using the CLASP system of prefabricated construction, hence York's inclusion among the so-called plate glass universities.[4] The buildings are connected by numerous covered walkways and bridges.
