So it still remains open whether and where there will be concrete or natural stone. Only this much is already certain: asphalt flats have no chance.
Money or beauty
As the head of the civil engineering department explained to the city council members, the concrete stone was more economical overall. Roughly estimated, the natural stone was allowed to be 100 euros per square meter more expensive than its concrete counterpart. And that makes a good 10.000 square meters will cost around one million euros.
Concrete blocks were also more favorable for later repairs. Natural stone, on the other hand, had the edge in terms of strength, cleaning, winter maintenance and appearance, according to hornung.
Although the city council had the opportunity to look at gangway zones elsewhere thanks to a specially organized trip, the building committee ultimately followed a proposal from city councillor bernd czelustek (SPD), who wants to see the conceivable materials on site. Ergo no decision was made, because before the next meeting samples will be laid out in the fubganger zone.
