Thank you very much for the helpful answers. Nevertheless, we are a bit shocked by the prices. That would mean we roughly have to calculate with the following values, if I understood correctly:
[*]Land: €0 (since already owned and fully developed) [*]House (excluding incidental construction costs): €510,000 [*]Incidental construction costs: €40,000 [*]Kitchen: €20,000 [*]Garage: €40,000 [*]Outdoor facilities: €25,000 [*]Total: €635,000
Recently, an acquaintance of mine, who signed an almost identical construction project with a local general contractor in April 22, showed me his cost planning and he planned with €420,000 for the house excluding incidental construction costs. Has there really been such a price increase in the meantime? I can hardly imagine that.
