'O' Level and 'A' Level pupils were educated at the original site in Alexandra Road, while the younger pupils mostly attended the Park Lane buildings (which dated back to 1904).New buildings were added to the Alexandra Road site at the beginning of the 1980s, giving younger pupils a chance to have three days a week at the main site, although they still used the Park Lane site twice a week until it closed in July 1990, being demolished the following year.
