Three storey family house in Petralona on a 6m. wide plot. The narrow and deep plot created a problem in providing sufficient daylight at the center of the building. The proposed plan incorporates a void above the first floor combined with a skylight. This allows the natural light to penetrate into all living areas without disrupting the continuity of the living and dinning area on the first floor. The ground floor hosts an office for the husband who is a professor and a guestroom.
