 By the end of the 1960s , traffic congestion had reached such a level that the use of the square as a modern wholesale distribution market was becoming unsustainable , and significant redevelopment was planned . Following a public outcry , buildings around the square were protected in 1973 , preventing redevelopment . The following year the market moved to a new site in south @-@ west London . The square languished until its central building re @-@ opened as a shopping centre in 1980 . An action plan was drawn up by Westminster Council in 2004 in consultation with residents and businesses to improve the area while retaining its historic character . The market buildings , along with several other properties in Covent Garden , were bought by a property company in 2006 .
