The domestic architecture in Mohenjodaro, a city of the Harappan civilization, exhibited several distinct features:
Courtyard-centered design: Many residential buildings in Mohenjodaro were organized around a central courtyard. The courtyard served as a focal point for various domestic activities and provided open space for tasks like cooking, weaving, and social interactions.
Privacy considerations: An interesting aspect of the architecture was the apparent emphasis on privacy.
Ground-level walls typically lacked windows, ensuring privacy within the household. The main entrance of the houses also did not offer a direct view into the interior of the courtyard, further contributing to privacy.
Multi-storey structures: Some houses exhibited evidence of multiple floors or access to rooftops. Remnants of staircases suggest that vertical expansion was employed in Mohenjo-Daro’s residential architecture.
Wells within houses: Wells were a common feature in Mohenjo-Daro’s houses. Many houses had wells, often located in a room accessible from the outside. These wells provided access to water, not only for the residents but potentially for passers-by as well.
