Construction within existing property holdings increasingly gains importance, because it is a side-effect of the demographic development. In the Western industrial countries, fewer people have more buildings at their disposal.
The population will decrease dramatically everywhere within the next 50 years: fewer new buildings are needed while old buildings remain empty and reasonable usage must be made of them.
Why build within existing property?
- the continued use of existing materials is ecologically sensible
- the higher qualification of the workforce brings about positive effects for the job market
- the reduction of energetically demanding new buildings considerably decreases the growing environmental pollution
- historical buildings are unique and confer an identity
