One day Mattias came to me with a tale that he would like of cardboard house. So we started hitting. when the time came to painting, he knew exactly what color the house should be, where come  windows and doors and what kind of paint in the rooms. When Mattias building was finished, Miika wanted such house as well. I let Miika also having to choose windows-doors locations and colors. (I fulfilled only the wishes of the architects :) )  So was the brief story of the birth of their houses.
