Since we are building in Munich and that is a category of its own, prices cannot be applied to all of Bavaria, but when we were at the model house in Poing at the very beginning to look at prefabricated house providers, there were some houses that would have fit into your budget "as they stand" without additional costs (so not with carpet :) ), and are already calculated for normal regions in Bavaria. Therefore, I would obtain offers from both solid house providers and prefabricated house providers and carefully consider beforehand which cost drivers are really necessary and which rather correspond to the current zeitgeist but not your own wishes. Electric shutters, KNX, basement, large garage, architectural extras (dormers, bay windows, canopies, balconies, galleries, huge windows), large kitchen with island and Bora, and everything that falls under the green "healthy living" marketing seems to be common nowadays, but none of this is necessary for a happy life in your own house. For the fireplace, the chimney cost us around €8,000, but there were extremely large differences for the stove itself, and here we also found nice models among the cheapest providers. We are building solid and had a cheaper base price for the house here than what prefabricated house providers calculated. However, we could not do "pre-sampling" here and now have to accept the price from our construction company for all special requests that were not clear to us when signing the contract or leave them out altogether. If possible, I would talk to previous builders from your region for both options (especially those who have just finished) to find out realistic prices for earthworks and general additional costs (house providers like to make this look mercilessly nice) and at the same time request all special wishes with the initial offer / go through the sampling center for the prefabricated house and inquire about the prices.
