>They have a mirror like coating which blocks the vast majority of heat and makes them mostly one way so I can walk around naked knowing it's basically impossible to see anything from the ground. Even without such coatings, no one can see inside your windows unless it's significantly brighter inside than outside. This is commonly known by anyone who watches police TV shows (the interrogation rooms take advantage of this effect, with very bright lights inside the room and the lights off in the observation room). So generally, no one can see in your window except at night. But even here, they'd need to be at a similar height in a neighboring building, or you'd have to be close to the ground and standing next to your window. >My building is 100m tall and I feel that's roughly ideal. I agree; too tall and there's too much space used for structure and elevators, and it takes too long to get to your floor. But a building like yours makes good use of the ground area with many dwellings.
