The aim of this project was to transform an existing residence into a three-apartment building, thus improving its functionality and renewing its morphology with new elements, inspired from the contemporary architectural vocabulary. The main idea is based on the separation of private and public spaces, using bioclimatic morphological tools, ensuring functionality and user comfort. Thus, a white compact volume was created, which hosts the private spaces and is open to the south. The common areas are morphologically distinguished from gray horizontal planes, which act as shading devices providing the necessary sun protection and allowing the necessary winter sunlight. Wood cladding accompanied by mild color variations, offer the desired optical alternations, neutralizing monotony. Finally, a photovoltaic system (BIPV) is integrated into the shelter of the roof garden, as part of the environmental approach to the overall design.
