The cabinet member for housing says a feasibility study for the redevelopment of an estate is under way.
The comments from Harrow Borough Council come after calls from people living on the Grange Farm estate who want the area redeveloped and new blocks built.
Cllr Barry Macleod-Cullinane said: "I'm pleased to say that one of the first things I did when I became housing portfolio holder was add Grange Farm to a list of feasibility studies for redevelopment, and I'm grateful to Cllr Simon Williams for arguing the estate's case.
“We have appointed architects and consultation has already started, with an interim report planned for cabinet in April.
“Redevelopment on this scale always takes time, and we still have work to do to get the funding we need, but I'm very pleased to have got the ball rolling after Labour let Grange Farm stagnate under their watch.
“Labour are suddenly pretending to care about social housing tenants because there's an election on the horizon, but let me be clear; in three years Labour did absolutely nothing to progress the rebuild of Grange Farm.
“This is despite residents reporting problems ranging from water contamination and sewer backwash to rats and building subsidence."
