A young renovator, Mateusz Niwiński, devotes himself to his favourite job, renovating old wooden house. He has showed us the houses he renovated and his own workshop, and briefed us the current circumstance of the wooden house renovation in Poland. Due to the particular history of Poland, wooden houses in Poland were mostly built up after World War II and many shabby houses are inhabited by the Jews. In Otwock, wooden houses scatter over the whole town. Many of them need proper renovations to sustain for a longer time, but some are even illegally occupied without being claimed by anyone.
