More than 250 homes could be built in a redevelopment plan designed to transform a 1970s housing estate.

Housing association Metropolitan Thames Valley has submitted plans to knock down 102 houses and flats at Westhorpe Gardens and Mills Grove in Hendon and replace them with modern, energy efficient buildings.

It comes after residents on the estate voted in favour of the regeneration in the first ballot of its kind held under new rules introduced by Mayor of London Sadiq Khan.

The mayor’s policy means all major regeneration schemes must receive a ‘yes’ vote from residents in order to get funding from City Hall.

Metropolitan said refurbishing the homes to bring them up to modern standards would have cost £3 million, and redeveloping the estate was a better option.

Under the housing association’s plans, the majority of the new homes would be one and two-bedroom flats in blocks of up to seven storeys, with a small number of three and four-bedroom units.

Almost all of the 251 homes provided on the development would be classed as affordable, with many aimed at retirement living.

The plans include 144 parking spaces and 116 cycle spaces, and some local residents have already raised concerns that the additional homes would add to traffic congestion in the area.

But a transport assessment submitted with the plans states that the redevelopment would have “no material effects on the local transport networks”.

Metropolitan’s plans were submitted in December and have yet to be considered by the council’s planning committee.
