A building may require to be altered at some point after it has been constructed and during its in-use period. This will necessitate alteration work to the existing design. Alteration work may be required for various reasons which can include:

* Factors unforeseeable at the design stage, e.g new thermal insulation standards come in
* Total or partial change of use e.g office block converted into housing
* Change of ownership necessitating enlargement, extension or other change
* Failure of building components in use
* Changing IT requirements
* Fashion
* Wear and tear.

=== Common examples of alterations include: ===

* Extension
* Partial demolition
* Linking or separating spaces
* Making or closing openings
* Retrofitting a new component or feature
* Refurbishing an existing component or feature
* Renovating an existing component or feature
* Repairing an existing component or feature
* Maintenance
* Decoration.

=== Alteration work may be instigated by: ===

* The building owner
* The building tenant (with the owner’s permission)
* The local authority (e.g if it needs to take urgent action or has instigated a compulsory purchase order).

Appointing a contractor to carry out the works may be on the basis of a firm that has successfully undertaken work in the past and is trusted by the client/building owner; or by inviting firms to tender for the work in an invitation to tender (ITT).
