Holden's original plan for the university building was for a single structure covering the whole site, stretching almost from Montague Place to Torrington Street. It comprised a central spine linked by a series of wings to the perimeter façade and enclosing a series of courtyards. The scheme was to be topped by two towers; the taller Senate House and a smaller one to the north. The design featured elevations of load-bearing brick work faced with Portland stone. Construction began in 1932 and was undertaken by Holland, Hannen & Cubitts. King George V laid the ceremonial foundation stone on 26 June 1933 and the first staff moved in during 1936, the University's centenary year. On 27 November 1936, a group of University officials, led by the Principal, Sir Edwin Deller, went out to inspect the work in progress. Suddenly, without warning, a skip being pushed by a workman overhead accidentally fell down and hit them. All were rushed to University College Hospital, where three days later, Deller died of his injuries. Due to a lack of funds, the full design was gradually cut back, and only the Senate House and Library were completed in 1937, although the external flanking wings of the north-eastern courtyard were not constructed. As he had with his earlier buildings, Holden also prepared the designs for the individual elements of the interior design. The completion of the buildings for the Institute of Education and the School of Oriental Studies followed, but the onset of the Second World War prevented any further progress on the full scheme.
