Various shell builders from 1,700 to 2,500 gross. I find these fluctuations extreme. Sometimes the steel costs more than the entire foundation + concrete walls.
Wow. That’s intense... My estimate concerns NRW - the more dealers you have in between, the more it naturally becomes. Factory + building materials dealer = end customer (basis for my price of 1,600) is obviously a different price than factory + building materials dealer + contractor ( + possibly subcontractor) = end customer. Sorry if I gave you the wrong idea there.... Currently, everyone wants to fill their pockets to the max and if everyone joins in, these are the "cartel structures" we currently have in so many sectors.
