For having a balanced life, it is necessary to make a balance between family life and private life. As much as we need to live with family members, we also need to have a secluded environment (being with ourselves, thinking, worshiping and resting). Mehregan residential complex is designed with 2560 square meters of substructure, on 4 floors and a basement. Each floor was divided into two residential units, taking into account the importance of separating private and public spaces, reducing unused spaces, considering three bedrooms with appropriate dimensions and paying attention to the lighting in all spaces. The design of the facade of the complex has been done according to the principles of aesthetics and creating a living and dynamic facade wall.
