Whatever the real estate market lacks, some bottlenecks are showing up more and more often.
In the conurbations, living space has been scarce and in demand for years.
While craftsmen, construction workers and other skilled workers can keep long order lists, it is no longer so easy to get hold of the necessary building materials.
The shortage drives up prices in many places and often enough causes a groan among builders.
But there is more that can be done than just complain.
If the processes can be reduced on the long road to new construction or renovation, many will benefit.
A new study from Leipzig shows the cost advantages of serial and modular construction or renovation: The attraction here is to take steps away from the construction site and carry them out beforehand.
Unfortunately, there are sometimes different building regulations that stand in the way, which is why it is best to quickly adapt and narrow them down between the federal states.
It is also clear that the construction industry should get much more involved and can use it to improve its processes.
Anyone who, given the staff shortages on the real estate market, thinks that it can't be so bad if building permits and completed apartments take longer should think twice.
