just as a suggestion: prices per sqm are generally only used to compare regional differences in construction costs. Munich is simply more expensive than Wanne-Eickel, etc. this way of thinking usually brings a builder absolutely NOTHING. what can be paid, what is the maximum one wants to pay, and what is offered at what price. THAT is important. moreover: the price per sqm can actually be tripled directly. sqm according to construction planning, sqm according to building application, sqm according to living space calculation... we fluctuate, depending on the document, between 162 and 212 sqm. if I took the sqm price as a benchmark, I could have built cheaply or expensively depending on the document. doesn't help at all
