The two-storeyed houses (the larger measuring 5 x 5 m.) have common outer walls. Preserved today are the magazines and workshops of the ground-floor and the underground rooms, reached by wooden ladders from the upper floor. The upper floor, the actual living quarters, is accessible by a staircase straight from the street. The walls of the lower part of the buildings are stone built, but the superstructure was built of mud bricks.
