Is there any discussion or experimentation on moving towards subterranean housing? Sleeping in a deep basement, basically.

Don't know about Sindh, but Babur used underground housing in Delhi around 1500 (and IIRC hated the hot weather).

Have experienced 47 degrees in Delhi, hate to think of 52.

That seems like a good idea, but none of my family's houses had any such livable basements.
