Eco homes in Rothwell have been shortlisted for a regional architecture award.
The Velux Carbonlight Homes, in Horse Fair Lane, are among 11 nominations on the shortlist compiled by the Royal Institute of British Architects East Midlands.
The semi-detached homes, which were designed by HTA Design, have a variety of energy-saving measures in place.
They are designed to retain warmth during the winter and its windows let in light but not heat during the summer.
There is solar heating, air-to-water heat pumps and rain water is collected to reuse.
Energy minister Greg Barker, speaking on a visit to Rothwell last year, said the homes could be an inspiration to the whole country.
The awards take place in Nottingham on Thursday, May 15, and will be hosted by architectural historian and BBC presenter Jonathan Foyle.
Other nominations include the University of Leicester’s College Court and the Byron Building at Nottingham Trent University.
