[In recent times] a major subject is public housing, which includes the famous Lansbury Estate, built in association with the 1951 Festival of Britain." Contrary to expectations, the River Thames landmark named "Blackwall Point" is not in Blackwall district but on the north tip of Greenwich Peninsula, which is south of the Thames. It is so named after the "Blackwall Reach" of the Thames. The 1980s, Blackwall saw the area first redevelopment project, a luxury housing complex called Jamestown Harbour over the Blackwall Basin, designed by WCEC Architects for the Wates Group and was completed by 1985. Jamestown Harbour was one of the first housing developments of the London Docklands. With its brick-built warehouse-style exteriors and distinctive blue and red balconies, it was designed to recreate the appearance of traditional river and dockside warehouses. In the 2000s, a residential development New Providence Wharf began to be built, which was designed and built by Skidmore, Owings & Merrill and Ballymore Group and saw the Ontario Tower and Providence Tower (now the Charrington Tower) completed in 2007 and 2016 respectively. Blackwall has never been an administrative unit and so lacks any formal definition, but it can be broadly described as the areas close to Thames on the north-east part of the Isle of Dogs peninsula extending eastward to the confluence of the Thames and Lea.  Blackwall was a significant part of the ocean-going port called the Port of London, connected with important voyages for over 400 years. On 7 June 1576, financed by the Muscovy Company, Martin Frobisher set sail from Blackwall, seeking the North West Passage. Walter Raleigh had a house at Blackwall, and in the early years of the 17th century the port was the main departure point of the English colonization of North America and the West Indies launched by the London Company. Until 1987, Blackwall was a centre of shipbuilding and repairing. This activity principally included Blackwall Yard, the Thames Ironworks and Shipbuilding Company at Leamouth, Canning Town (part of whose works spanned the very informal border of the very small one-road, one unit deep area of Leamouth), and the Orchard House Yard. Blackwall Yard (two of whose former dry docks can still be seen around the present-day Reuters building) built the first Blackwall Frigates. Blackwall today is still a part of the Port of London as Northumberland Wharf is still retained as a working wharf, this has special status by the Mayor of London and the Port of London Authority (PLA) as a safeguarded wharf.
