The Harappan towns exhibited well-planned streets, lanes, drainage systems, and fortified structures. For construction, the Harappans used baked and unbaked bricks as well as stones. The towns followed a grid pattern, with systematically built drainage systems.
Houses were primarily made of mud bricks, while drainage systems were constructed using burnt bricks. Many houses had multiple floors, with some featuring staircases, indicating an upper level. In Mohenjo-Daro, the town was built on a raised platform and had two distinct sections: the citadel and the lower town. The houses were designed with multiple rooms, bathrooms paved with burnt bricks, and proper drainage systems. Several homes had a central courtyard surrounded by rooms.
