The plan of the houses was such that they had only one access gate to the outside; there was a wall all round and adjacent houses had just a small portion of land in-between them as a separator. The fact that the openings did not face the main street provided privacy for the occupants.
The houses were a series of rooms which opened on to a courtyard that was centrally located. Ratnagar adds that the open courtyard provided lighting into the houses, space for any community activities, absorbed most of the heat during summer and radiated heat into the houses during winter. The houses were either single roomed for the lower class or up to twelve rooms.
