The shape of the triangular ground is connected to the street from one side and to the pavilion (the main axis of the walk) in Shahid Keshvari town of Isfahan from the other side. By placing the volumes of the building along the southwest and northeast (Ron of Isfahan), we were able to control the angle of radiation to the body of the building in a longer time during our radiation, and in this regard, with acceptable retreat and depth on the ground floor despite creating movement space. In a semi-open space, protect users from direct sunlight.
