We have installed a heating and water-heating system using heat pumps, which guarantees high environmental efficiency. We renovate our buildings with an eye to high-performance insulation. The most recent part of La Bastide dates back to 1904, so we have brought a building that is over 100 years old up to the latest environmental standards. We prefer renovation to construction. We use local craftsmen for all our work, and as far as possible we avoid sourcing from manufacturers. A significant proportion of our furniture and infrastructure is custom-made by local craftsmen. For all new investments, we give priority to environmentally-friendly solutions that fit in with the local fabric.
