Gatecrasher One was a nightclub in Sheffield, South Yorkshire, England. The club was a converted warehouse owned by the Gatecrasher dance music brand. The nightclub was originally named The Republic, but this was changed in 2003 after a £1.5 million refurbishment. On 18 June 2007 the venue caught fire and partially collapsed. The building was later demolished. History Gatecrasher One started life as the Roper and Wreaks works, on Matilda street, and was constructed around 1910. The building was a two-storey brick built warehouse and remained an industrial building until 1986. In 1991 a planning application to convert the building into offices was submitted. These plans were never carried out and a number of applications were submitted to convert the building into a nightclub. The conversion took place in 1995 opening to the public on 1 December of that year. The club was initially a financial failure, failing to attract the numbers expected. The fortunes of the club were changed when, in 1996, the Gatecrasher night started to use the building for Saturday night events, initially as a few one-off events, eventually becoming Gatecrasher's permanent home. The rise in success of the Gatecrasher brand coincided with financial troubles for the owner, leading to Gatecrasher buying the venue at a reported six figure sum. Gatecrasher continually improved the venue, adding a VIP room and replacing the original crane in the main room with the lighting rig arches. In 2003, Gatecrasher repositioned the brand and after a refurbishment, decided to rename the club. The Gatecrasher brand planned a large expansion of clubs, and the "one" in the name was to be the first of 10 clubs. The other clubs were not however called 2, 3, 4, and 5. (Leeds, Nottingham, Birmingham and Watford). Club The conversion from a warehouse to a nightclub was designed by Mills Beaumont Leavey, a Manchester-based architect, who proposed to keep the main body of the building but to create a new extension in a Postmodernist style. Internally the building was split into five distinct areas; the Foyer, Main Room, Electric Box, the Lounge and the VIP Pod. The Building was constructed on sloping topography and therefore the five areas were on differing levels with Main room being the lowest, Lounge the highest with Foyer and Electric Box in-between. VIP shared the same floor space as Lounge. The focal point of the club was the main room. This
