The school is housed in a number of buildings in the centre of Glasgow, upon Garnethill, an area first developed by William Harley of Blythswood Hill in the early 1800s. The most famous of its buildings was designed by Charles Rennie Mackintosh in phases between 1896–1909. The eponymous Mackintosh Building soon became one of the city's iconic landmarks and stood for over 100 years. It is an icon of the Modern Style (British Art Nouveau style). The building was severely damaged by fire in May 2014 and destroyed by a second fire in June 2018, with only the burnt-out shell remaining.
