In 1952, the Artizans, Labourers & General Dwellings Company was renamed the Artizans and General Properties Company Ltd.[1] The combination of a taxation system biased against private property developments and legal restrictions on raising rents made the company's traditional model unprofitable, and it began to divest itself of its original low-rent developments and instead to sell vacant houses on the estates and to reinvest in non low-rent housing and commercial property, especially in the United States and Canada where depreciation before tax was permitted.[9] In 1966, ownership of the four original London estates (Shaftesbury Park, Queen's Park, Noel Park and Leigham Court) was transferred to the respective local authorities as council housing – in the case of Noel Park, the newly created London Borough of Haringey, which purchased the 2,175 properties comprising the Noel Park estate for a total of £2,917,000 (approximately £54.7 million today)[14][59] – leaving 377 homes at Pinnerwood Park in Pinner as the last residential estate in Greater London owned by the company.[9]
