I’ve often that about that if I could design a house, I’d have a room just like this. Like there would be a section of the house that was tower like and the only way to get to the room at the top would be to take an exterior balcony-like-staircase from the second floor to the room in question - the sole room on the “third floor”.

There’s just something about a room like that that makes it fell so isolated, peaceful and serene. And the exterior access makes it feel like a little adventure getting there. Like if the weather were bad you might opt not to go there because it would mean gearing up to make the trip.
