The core of a building is often placed in the center of a building, but it can also be placed on a side of a building, and there can be several cores in a building. Cores on a side of a building are known as perimeter cores, are completely inside the building and can allow for more uninterrupted, column-free floor space within a building.
A shaft equipped with ladder rungs for personnel access. In civil engineering a shaft is an underground vertical or inclined passageway. Shafts are often entered through a manhole and closed by a manhole cover. They are constructed for a number of reasons including: For the construction of a tunnel
A building code (also building control or building regulations) is a set of rules that specify the standards for construction objects such as buildings and non-building structures. Buildings must conform to the code to obtain planning permission , usually from a local council.

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 ]
Shaft mining or shaft sinking is the action of excavating a mine shaft from the top down, where there is initially no access to the bottom. [1] Shallow shafts , typically sunk for civil engineering projects, differ greatly in execution method from deep shafts, typically sunk for mining projects.
Airshaft/lightwell in a building in Lombardy, Italy. In architecture, an airshaft, also known as a lightwell, is typically a small, vertical space within a tall building which permits ventilation of the building's interior spaces to the outside. [2] The floor plan of a building with an airshaft is often described as a "square donut" shape ...
