Sorena Building for its special situation, required an attractive and unique facade. the ground floor due to its direct contact with the outside, was considered different from floors but in harmony with the entire façade. After determining the level of openness in view of other floors, based on interior spaces, the walls around opening connected to recessed windows with different slopes. Since the southern facade receives the greatest amount of light during the day, the suns direction provides variety in interior spaces. The pattern used in the facade was extended to inside and created negative spaces that provided a good place to grow plants and induce a sense of calm and peace.
