The room with the angled ceiling probably was the patio or a screened porch- my parents enclosed their porch for a den, and it had the same angled ceiling.
Get the house that feels like you, is what I’d recommend. My house is a small older home, just a few inches of being big enough for 3 of us, really, but I love it.
I would love to buy one of those decommissioned missile silos or communications bunkers.
That would be my dream home.
