A solar and wood house in Lorraine: work, plans and photos self-construction

Here is the complete presentation of a three-energy heating house: solar, wood and electric supplement located in Lorraine. This house "was" an electric house from the 80s that its owner completely transformed himself into a solar and wood house. The solar and wood duo constitutes for us the current compromise, the most econological of the moment. This […]
