The largest high-rise housing estate in Britain was constructed at Castle Vale with 34 tower blocks on the site of Castle Bromwich Aerodrome. This became an unpopular area as it began to suffer from social deprivation and crime whilst the buildings were poorly constructed leading to maintenance issues. To tackle the downward spiral of the estate, one of the largest tower block demolition and renovation programmes anywhere in Europe began in Castle Vale, with the construction of new buildings, squares and green public open spaces.
