£100,000 funding from Derbyshire Dales District Council has transformed a number of "non-traditional" homes at Matlock's Hurst Farm.
Re-cladding work on 11 of the privately-owned 1950s' homes is dramatically improving the energy efficiency of the properties, saving on energy bills and reducing CO2 emissions.
The Council funding came from government grants - and installer Westville has also attracted additional government funding.
Part of the ongoing Hurst Farm Regeneration Project, the recladding scheme has thrilled residents, including Michael and Marilyn Bailey, who have lived at their home in Overdale for the past 46 years - and it now looks like new.
Mr Bailey said: "As soon as Westville started the insulation work in February the house became immediately warmer and we've really noticed the benefit."
As with other elements of the Regeneration Project, the District Council is working with the Friends of Hurst Farm community group on the non- traditional homes revamp.
Said Director of Housing Rob Cogings: "There are 43 non-traditional homes in total at Hurst Farm and this important work takes the thermal insulation from the standards of 1950s to that of a new home built today.
"The finished properties really do look like new homes and help to improve the look and feel of the area as well as improving the energy efficiency of the homes. This helps residents, many of whom are elderly, and the planet."
Cladding works reduce energy costs by 40% to 50% and reduce CO2 emissions by 30 tonnes per property over 20 years - and now the District Council is working on proposals to deliver a second phase of improvements later in the year.
