Penrose High School (One Tree Hill College) - One Tree Hill College is a state coeducational secondary school located in the district of Ellerslie in Auckland - One Tree Hill College, formerly Penrose High School, opened on 1 February 1955 - Penrose High School is said to have been designed with the view that it could serve as a hospital in the event of war (it came onto the drawingboard at the start of World War II) - The site was difficult to build on, not least because of the large amounts of volcanic rock that had to be excavated.[4] In the first year, after the initial buildings were opened, £48,000 had to be spent developing the school grounds. It was to take several years before the outworks were completed
