The nightclub was located on Derby Road in
Bootle, north of the city of Liverpool, in a converted warehouse. The building was originally an
Owen Owen warehouse, which was purchased by steel magnate James Spencer in the late 1980s to convert into a nightclub and snooker hall. A "Heritage Market" was opened shortly after to make use of the large unused lower floor space at the rear. Originally opened in the late 1980s as a
snooker hall as the venue did not sell alcohol. Quadrant Park's main period of activity began in early January 1990 with a capacity of 2,400, Quadrant Park began focusing on house music in early 1990. The club was dubbed "The Quad" and in October 1990 it opened the Pavilion, the first weekly legal all-nighter in Britain. Pavilion was put on in the basement below the main club. Some party goers would travel long distances to get to the venue; from London, Glasgow, Birmingham and even as far away as Aberdeen. Near the end of 1990, the club obtained a licence to stay open to six o'clock. ==DJs==
