Located under the hill of Filopappos, this house is situated in a narrow plot, between two buildings. The main facade is seen from the street side and there is also a backyard. It is an adaptation of the modernist concept of the “primary habitable box”, or the minimum “life container”. Instead of a design made by plates and free surfaces, hereby, the treatment of a solid “box” shape is prominent and adds to the building’s integration to the neighborhood. Despite the outer boundary that shelters the delicate intimacy of “private life”, the house retains a social façade, through a balanced visual and spatial intercourse between public and private.
