The House ABCD+

The ABCD+ House, designed by French builder Cecile Robin and using Lafarge materials, was inaugurated in 2012 in Roanne (France).
This
positive-energy detached concrete house, the result of a close partnership with building firm Cecile Robin Construction, is inspired by the PRO-eco initiative set up by Lafarge in France to make
sustainable construction simpler for building professionals.
Combining
traditional techniques and
innovative materials such as pumice-stone concrete block, the house meets the requirements of
2020 Thermal Regulation as of today. It also offers an urban, architectural and environmental answer to the new challenges of the sustainable city. The house was awarded the
golden medal in the "Urban Challenge" category for the House of the Year 2012 classification by French Houses Union.
Follow our guided tour around this new concept for detached aesthetic and affordable positive energy house made from concrete.
