The council has revealed it will change the number of affordable houses required on each large development despite a consultation of residents not being in support.

A Unitary Development Plan (UDP) inspector recommended Richmond upon Thames Council insist on 50 per cent of houses on a new development being affordable, which is in line with the number recommended throughout London.

But the former Conservative administration had reduced the amount of affordable housing to 40 per cent, a move described as foolish by the borough's environment chief but which has a larger level of support from Richmond residents.

During the Local Development Framework consultation in October and November last year, 49 per cent of respondents voted for 40 per cent affordable housing, while 39 per cent wanted 50 per cent.

Cllr David Marlow, Conservative deputy leader on Richmond upon Thames Council, said: "The higher target of 50 per cent was rejected by a clear majority, the survey confirms the policy adopted by the previous council.

"A 40 per cent target is realistic and achievable, and it is what our residents want. To impose a higher target on developers is counter-productive, it will discourage development and sensible housing provision.

"Residents do not wish to see a radical change in the character of the borough, they have our whole-hearted support."

Cllr Martin Elengorn, Richmond council cabinet member for environment, said: "Far from causing a radical change in the character of the borough, insisting on 50 per cent affordable housing for larger developments will assist younger and less wealthy residents stay near their friends and relations.

"The UDP Inspector recommended a 50 per cent level and the Tories foolishly reduced it to 40 per cent. We believe the Inspector was right and we will reinstate his figure."
