The lot is situated in the outskirts of Athens. It has extent of 1.000 m2 and orientation in the small side southerner. The project concerns two private residences with basement and a common yard. Houses are placed in regression to the street and they are downgraded hypsometrically so that their privacy is ensured. Construction process consists of a metal frame resting on concrete walls. The roof is cladded with zinc and glazed windows form the facades. Designing the two residences as an entity is the subject of the study. Basic synthetic principals of the design are: Dissolution of limits between lived space and natural, the unification of the internal of the buildings with the surrounding external space. Organisation between private and common spaces through the concrete wall connecting the two sides of the building. Plasticity of form and the creation of a unique geometry through the use of metal construction. Forming of views in the interior and exterior of the building through openings that are adapted in the metal roof.
