Just realized nobody ever talks about how the 1918 flu changed home design, and my grandma's old house in Ohio proves it | Alternate History Scenarios

So I was cleaning out my late grandma's house in Dayton last month and found a stack of letters from her mom written in 1919. They kept talking about "the sleeping porch" and how the whole family moved out there when anyone got sick. I always figured sleeping porches were just a Southern thing for hot summers, but turns out a lot of houses built between 1918 and 1930 added them for fresh air and to keep sick people away from everyone else. What bugs me is every alternate history thread I see about the Spanish flu jumps straight to "what if it was worse" or "what if it hit in wartime" and nobody ever brings up how it actually reshaped ordinary houses. Those porches, the push for open windows in schools, even some of the bungalow layouts in older Midwest neighborhoods all trace back to that one outbreak. My grandma's house had one and I never once asked why it was there until I read those letters. Has anyone else dug into how past pandemics changed everyday buildings instead of just the big political stuff? I feel like that angle gets skipped way too often.
