on the campus buildings since the 1960s, and featured a design of aluminium cladding for the building that proved controversial. That same year a Highfield Planning Group was formed under the direction of Professor Tim Holt to oversee how the University and the campus could develop further, given that the new Mountbatten building had used the last of the University's building plots. As the University had now exceeded the Master Plan set out by Sir Basil Spence set out in the late 1950s, a new one had to be developed, so the University approached Chesterton Consulting to devise a new one. These new plans had to satisfy the planning laws on parking that required a certain number of new spaces for every development, requiring the plan to include three multi-storey car parks and a reconfiguration of University Road. None of these eventually occurred as the University and the Consultancy lobbied the council and were able to change the guidance to allow further development to be easier. To cement the end of Spence's master plan the next new building to be constructed on campus, the University Health Service in 1992, breached one of Spence's fundamental principles by blocking the flow of vegetation linking the western gardens with the common. The new master plan also saw the expansion of the University onto the new Avenue Campus, resulting in the Arts subjects to move to that new campus. As a result, the Arts buildings were vacated and it led to several departments changing buildings around 1995 and allowing the refurbishment of several of the 1960s building stock. In addition, a programme of new building works commenced: the Health Professional and Rehabilitation Sciences building was built in the North East corner of the campus in 1994 and featured a modern design by Sir Norman Foster; the Students' Union Retail Centre was added in 1995/6 and completed the side of a new social square outside the Union, all constructed and landscaped by London practice Allies and Morrison; the Social Sciences Graduate Centre in 1997 (accompanying the Murray building) and the long-awaited Synthetic Chemistry building which was located adjacent to the existing chemistry buildings, replacing some older and smaller buildings on the site and thereby closing off Engineering Square, and was built between 1996 and 1998 according to the design of London architects the Wilson Mason Partnership. 1998-present Following the lobbying of the council from the
