I live in a neighborhood with 3 house styles; each has a fixed number of floors. The townhomes all have 8' ceilings, a basement, 1st, a second floor, and an attic or loft. All basements are walkout so i count them. I-joists are about 18 inches. So the townhomes are ~ 11 meters.

The single family are basement, 1st, and second, with 10" main floor and 8" second floor, then they have 16' attics, which puts them ~ 13m

The apartment complex has 5 fixed floors. It was trickier because I don't know the internal structure, nor the height of the decorative crowns, so I took a Google Earth look at the side of the building, drew a 45-degree line down from the top, and measured the bottom of the triangle
