3E single family house. This house will be not only ecological, but also energy independent – self-sufficient – thanks to 3E and photovoltaic systems.


Paul, York

Building a house by yourself is very satisfying. After a short training by 3E I was able to build my own home with my father! Although it is not heated inside yet, it is already warm. I can sincerely recommend SYSTEM 3E!
