Recently, I retired and visited an old friend who is an architect and also retired. Knowing that I wanted to build a house for my old age, he recommended that I take a look at a new building with original architecture right next door. So, I went there, and someone from the construction company, an association, guided me through the building which covers 780 m2 on 5 half-levels. It includes a room for worship services as well as community spaces built of concrete with wooden frames and straw bales as insulation layers. I was very surprised by the pleasant atmosphere of the place despite the strong presence of concrete. Having worked my entire life as an EDF representative in a world of concrete, this was the first time that I felt comfortable in concrete surroundings – even in the basement! Here, I didn’t have the usual impression of coldness or lifelessness. On contrary, there is a sense of well-being emanating from this place. Upon asking questions about it, my guide informed me that this concrete contained a biodynamic additive called Pneumatit®. With this information in hand, I contacted Pneumatit France’s representative via their website’s contact form. Now I want to build my new house using Pneumatit!
