Core (architecture)

In architecture, a core is a vertical space used for circulation and services.

A core may include staircases, elevators, electrical cables, water pipes and risers.

A core may also serve a key structural role in a building, helping support it and acting as a load-bearing structure with load-bearing walls.

[3] It is generally desirable for a core to be as small as possible to maximize floorspace within the building.

A large portion (over 40&) of offset core buildings were built after 2010.

Simple core arrangement – stairs "wrapping around" elevator shaft.
