Tenants in Beaconview, Broome, Stanton and Sheapecote Houses on Charlemont Farm have seen their homes transformed over a two-year period.
External improvements including new roofs, insulated cladding, windows and balcony doors have given the blocks a new lease of life. Internally, each flat has new electrical rewiring, heating and ventilation systems and a new front door.
Councillor Paul Moore, cabinet member for regeneration, said "These improvements have made a massive impact on both the external and internal appearances of the blocks.
The much-improved insulation provided by the eye-catching external cladding and the new enegy-efficient windows will help tenants in lowering their fuel bills.
The landscaping around the blocks has given the area a real boost."
