I have not had an attic since I lived with my parents. It’s been dorms, apartments, rental houses (you just don’t go into the attic in a rental house) and then I bought the little flat-roof house on Grover. So when we designed our house, there was very little emphasis on the attic. We put in just enough for the AC and a few boxes.
Still it’s my first attic. It’s the space above the master closet and bath. It goes from about 5ft of headroom to about 3 feet. I took some pictures just to show how small it is.

Again, note to self: Don’t tell wife how I got up there.
