As a frequent visitor to west ham during my misspent youth, I must point out that custom house was closed for redevelopment a mere 44 years and 8 months ago!. Like you say losing stadiums to the developer is nothing new. Bristol knowle was one of the first big venues to go at the end of 1960, quickly followed by stoke sun street, southampton, Norwich, Edinburgh meadowbank and glasgow white city by the end of the decade.
