How the internal relationship of the house as an architectural cell with the city was the main intention behind designing this project. The location of the building is the land obtained from the owner’s old building with the dimensions of 10×20 meters, placed in the crowded street of Ostadan and the 8-meter back alley, in Hamedan City. The main problem is seeking a response to the issue of the direct/indirect relations in the house living space with these two external passageways/cities. In the old houses of Hamedan City, the porch is considered an active living space connecting the indoors to the outdoors.
