The Oliver Close Estate and the Cathall Road estate were the first to be completely redeveloped by demolition and rebuilding with the help of the multimillion-pound Waltham Forest Housing Action Trust scheme during the early 2000s. The redevelopment of the problematic Avenue Road Estate followed. Demolition of the last large high-rise estate in the area, the Beaumont Road Estate, began in 2006. It has since been almost completely redeveloped. Indeed, the only remaining 20-storey tower block left in Waltham Forest - from a 1970s peak of 20 across the borough - is the Northwood Tower in Walthamstow.
