Skyscraper buildings are usually built by constructing a core column in the building that is load bearing and is the main support for the construction. On the core, the various floors are effectively ‘hung’ from that support and then curtain walling techniques are often used to clad the exterior.

When in use, this core also is used to contain all main service provisions. It will include the stairs, lifts, electrical and information systems, cabling, water, toilets and fire facilities. This keeps all services neatly together and provides a larger, undisturbed area for occupiers.
