Faizi and Fazl were two brothers. Faizi's house was detached from Fazl's house. It consists of 3 rooms and a long veranda. Like most of the domestic buildings in and around the city, the outer walls slope upwards and are broader at the base than at the bottom. Only over the eastern room, there is an upper apartment, covered by a wagon vaulted and ribbed roof.
