The idea that Bristol's main shopping area should be moved away from the Castle Street and Wine Street area was first proposed to Bristol Corporation's Planning and Reconstruction Committee by the Multiple Traders' Federation (MTF), representing the larger retailers and chain-stores, in October 1943. They suggested that the pre-war shopping area should be set aside as a civic area with perhaps a concert hall or similar building and an open space, and that the central shopping area should be moved to a less-constrained site. This suggestion formed part of the City Engineer's Master Plan of February 1944, which envisaged that the area would contain a limited number of buildings such as a conference hall, with underground parking for 2,000 cars. The removal of the shopping area was considered desirable because the fire that had destroyed so much of the area was in large part sustained by its congested nature, and in any case many of the chain-stores represented by the MTF wanted larger sites.
