Babak project is a villa residential building located in Babak street of Mashhad. In this project, a small protection unit with 45 square meters, the main building facade, and the open space of the building were designed and reconstructed. One of the most critical parts of this project’s design and implementation process was changing the warehouse space on the damaging floor to the caretaker unit. This section established a garden pit in the entrance section to provide direct access to natural light and strengthen the unit’s privacy.
