Building component

For a list of articles on Designing Buildings Wiki about building components, click here.


A component is a constituent part of a building (or other built asset) which is manufactured as an independent unit, subsystem or subassembly, that can be joined or blended with other elements to form a more complex item. Generally, components are ‘self-contained’ and sourced from a single supplier, typically the complete unit provided by that supplier rather than its constituent parts.

A combination of components may be described as an ‘assembly’.
