late 1930s and 40s the university college again started to run out of room and so needed to improve their estate. New teaching buildings were constructed for Chemistry in 1937, Physics (Now occupied by the Estate department) in 1938 and Engineering in 1939. In addition, the Hartley library was built in 1935 following a donation of £24,250 (£1,460,500 in 2012) from the daughters of Edward Turner Sims. It was designed by Gutteridge and Gutteridge, with Sir Giles Gilbert Scott, and plugged the gap intentionally left between the original two buildings with library facilities, seminar rooms and a new reception for the university college. All of these buildings had been constructed on the eastern side of University Road but in 1939 the Western side of the campus was developed with the construction of the West Building in 1939/40. Built on the site of Sir Sidney Kimber's brickyard, the building housed the refectory, common rooms and the Students' Union and was further extended to include an assembly hall, suitable for performances and examinations, in 1948. Following the war, much of the University's capital budget went into purchasing new land, including the brickworks behind the West Building. At the same time the Institute of Education was given its own building in 1948, extensions were made to the Zoology building and the remainder of the Chemistry building completed. 1950s and Basil Spence masterplan Following the creation of the University by royal charter in 1952, numbers at the University were set to increase again to around 2,500 by the mid 1960s. As a result, the university estate needed to expand and the inadequate facilities needed to be replaced. The end of the 1950s saw an explosion of building work in a whole variety of styles. On the West site, a new computer building was built in 1958 and a Tidal model of Southampton Water constructed in 1957 (now the John Hansard Gallery), both designed by Ronald H Sims. In addition, Gutteridge and Gutteridge were undertaking several extensions to pre-existing buildings: the Physics building in 1960, the Education building in 1961 and the Library in 1959. Whereas the first two extensions were in the same style as the earlier building, the new Gurney-Dixon library extension was built in a modernist style, linking the three main buildings together and providing space for 150,000 books and 400 readers. The remaining buildings were built under the direction of Sir
