This project is a redesign and change of use from residential to commercial with an entire infrastructure of 600 square meters and includes four units on two floors and a shop unit on the ground floor located on Qarani Street in Mashhad. In this project, two residential floors with two separate accesses (two public stairs) have been changed to office units, and a shop unit has been designed and implemented on the ground floor. The employer wanted to create two management units and two units to deploy the sales team. We developed a personal elevator for easy access to the sales units. Also, the main view of the project was redesigned and executed. The design and implementation of this project took about 14 months. The highlight of the redesign was the careful look at the move. In this project, there was an attempt to design a solid and efficient motion circulation of the effects in space for communication between units and effective interaction between the sales team and the management department; As the vertical connections in the project play the role of vertical and horizontal connecting arms between the units.
