The Strand Campus is the founding campus of King's and is located on the Strand in the City of Westminster, sharing its frontage along the River Thames. The original campus comprises the Grade I listed King's Building of 1831 designed by Sir Robert Smirke, and the King's College London Chapel redesigned in 1864 by Sir Gilbert Scott, with the subsequent purchase of much of adjacent Surrey Street (including the Norfolk and Chesham Buildings) since the Second World War and the 1972 Strand Building. The Macadam Building of 1975 houses the Strand Campus Students' Union and is named after King's alumnus Sir Ivison Macadam, first President of the National Union of Students.
