This document discusses the advantages and challenges of self-building a passive house. It provides two examples of self-built passive houses in Italy, Casa C and Casa C2, which achieved very low heating and cooling demands. While self-building has economic benefits and allows one to customize their home, it requires meticulous project management and precision in construction. The process also takes a long time, with construction spanning over a year for the example projects. Overall, self-building a passive house is difficult but achievable with careful planning and teamwork.
