Leader of Lambeth Council Steve Reed was shown round SE11 by local councillors Mark Harrison and Steve Morgan last week.
They took him to the Vauxhall Five Estate to celebrate the work taking place to transform residents' homes.
After decades of neglect, the blocks are having new windows, roofs, and concrete repairs, as part of a multimillion refurbishment.
Residents have campaigned for new windows for many years - the previous windows were over 60 years old and left people's homes draughty and cold. Local councillors and Vauxhall MP Kate Hoey supported the residents campaign and persuaded the Council to put the Estate at the top of Lambeth's housing capital programme.
Cllr Mark Harrison said 'it was great to be able to show Steve Reed the results of years of campaigning and lobbying - the new windows are already making residents' homes warmer and cheaper to heat.'
