We built this house around a piano whose sound we had to contain. In an area of 220 sqm, we had to make sure that the pianist obtained right acoustic conditions in a space large enough to give recitals and group lessons. At the same time, the house had to protect the neighbors and the other residents of the house from the sound. We surrounded all edges of the site with tall stone walls. With concrete beams crossing them, we suspended all the second floor leaving the ground floor almost empty, isolating the piano.
