I actually DID mean to include apartments in this too but everyone is misunderstanding the question I feel sob The floor on the building you are on is indeed what I meant! Whether the whole building is your house or not is irrelevant ;v;
My room and my bathroom are actually technically the only rooms on the second floor? There's a staircase that goes up to a platform which has my bathroom on the right and my room ahead. So it's a miniature floor, I guess
My moms place is an apartment, for which our place is the second (Highest) floor. The PLACE ITSELF (Like our door letter, hard to explain) doesn't have any "Floors" lol. However I sleep in a bunk bed so... Idk how to define that. For my dads place, he lives in a townhouse where my room/the guest room is on the third floor, under the attic.
"second floor" (or first floor, if you're in Europe/Britain, i think) in theory--but our house it what's known as a "split level" so the second floor isn't actually a second story??? idk architecture is weird brah
