The renovation of this 45-square-meter apartment in Athens focuses on maximizing perceived volume through strategic spatial organization and material continuity. To expand the compact footprint, the intervention utilizes spatial techniques that blur the boundaries between interior and exterior, as well as private and public zones. The layout adopts an open-plan format anchored by a central inox-clad volume. Positioned along a lateral axis, this metallic core houses the bathroom and kitchen facilities while reflecting natural light deep into the floor plan. A mirrored pivot door enables spatial reconfiguration, blurring the boundary between the interior and the cityscape when closed, and facilitating transversal views when opened.
