A small house for a professional musician with two small children presents a great design challenge – the bedrooms require a good isolation from his music practice. To achieve this goal a single-storey layout is chosen and the living room with the piano is separated by three doors from all the bedrooms. The living room has a high space inside with a one-and-a-half storey height. To compensate for the small plot, a habitable roof-terrace is created on top of the bedrooms area, accessible via an open stair fat the back.
