ACKGROUND
With greater flexibility in planning, approvals opportunities exist to
rehabilitate existing buildings. The rehabilitation of old industrial buildings
is as an example of successful commercial redevelopment in many cities
around the world. There is a potential to lower building costs and provide
a mix of desirable building characteristics. However, the reuse of existing
structural elements depends on many factors, not least fire safety,
energy efficiency, and regulatory requirements, all of which need to be
critically reviewed to determine the advantages and feasibility of reuse as
opposed to demolition.
