designed by Edmund Anscombe. He was also responsible for the Rectory, 1913, the principal's onsite residence. The Shand Building, originally called "Shand Hall" cost 3,600 pounds. The following year it was extended to a design by Harry Mandeno (1879–1972). A memorial arch at the entrance to the grounds, built in blue stone and Oamaru stone and designed by Leslie Coombs (1885–1952) was unveiled in 1923. In 1920 the Fulton Building provided six additional classrooms, but this has since been replaced with the gymnasium complex and rehoused swimming pool designed by E.J. Ted McCoy as part of the later major restoration and redevelopment of the school's buildings. There is a teaching block, named after a former Rector, Mr. W.J. Morrell, which was erected in 1961 to a standard Ministry of Works design, though contextualised with blue stone fascias by the architect Ian R McAllum. A grandstand with similar fascias on its rearward elevation forms part of a quadrangle, with the Morrell building, behind the Lawson building. This was also designed by McAllum and built from 1962 to 1963. It has a cantilevered, multiple-gabled canopy added in 1964. Specialist science laboratories designed by Angus Black were constructed in 1967 and were named after the pioneering plastic surgeon Sir Archibald McIndoe, an Old Boy of the school. Mr D J MacLachlan, Rector from 1963 to 1985, worked tirelessly for the construction of the main teaching block which now bears his name. This is part of the major restoration and redevelopment which saw the refurbishment of the Main Tower Block, the central feature of which is the Maurice Joel Theatre. It also involved the construction of several large new buildings, forming a new quadrangle around the former Green in the greatest expansion of the complex since the 1880s. This considerable undertaking, designed by E.J. Ted McCoy was completed in 1983. The new buildings, though unmistakably Modernist, nevertheless sit very comfortably with the old. Where Lawson's tower block is an exemplary composition in the Scottish Baronial style, taking its inspiration from the 16th-century tower houses and reading something like a toy fort or a castle to a modern eye, McCoy's blue stone aggregate and fair face concrete echo its materials while the new complex's gun slot windows are a playful reference to the Maginot line which echoes the old building's military theme. The new buildings are also very modestly set below the old so the
