An architect can plan for either a single-story building consuming the entire allowable area in one floor, or a multi-story building that rises higher above the plane of the land, but which must consequently result in a smaller footprint than would a single-story building of the same total floor area.
The attic or loft is a storey just below the roof of the building; its ceiling is often pitched and/or at a different height from that of other floors. A penthouse is a luxury apartment on the topmost storey of a building. A basement is a storey below the main or ground floor; the first (or only) basement of a home is also called the lower ...
Use Newton's law of gravitation to calculate the radial altitude of both the ground and the roof. The difference will be the height of the building. Tying a piece of string to the barometer, which is as long as the height of the building, and swinging it like a pendulum, and from the swing period, calculate the pendulum length.
Hong Kong law Chapter 123F, Building (Planning) Regulations, Regulation 23 sect 3 sub-paragraph (a) defined that: Subject to sub-paragraph (b), for the purposes of regulations 19, 20, 21 and 22, the gross floor area of a building shall be the area contained within the external walls of the building measured at each floor level (including any floor below the level of the ground), together with ...
The current tallest residential building, Central Park Tower, was topped out during September 2019 and completed in 2020. The percentage of residential buildings whose height exceeds 200 metres increased from 34 percent in 2009 to 45 percent in 2010, [8] making Burj Khalifa the world's first megatall building to include residential space.

In architecture, the slenderness ratio, or simply slenderness, is an aspect ratio, the quotient between the height and the width of a building. In structural engineering , slenderness is used to calculate the propensity of a column to buckle .
For buildings with one or two floors, h is the height of the building and A is the flow area of the openings. For multi-floor, high-rise buildings, A is the flow area of the openings and h is the distance from the openings at the neutral pressure level (NPL) of the building to either the topmost openings or the lowest openings.
Mechanical floors are generally counted in the building's floor numbering (this is required by some building codes) but are accessed only by service elevators. Some zoning regulations exclude mechanical floors from a building's maximum area calculation, permitting a significant increase in building sizes; this is the case in New York City. [1]
