So if you don’t want to compare apples and oranges, I would first have a building application plan created by an architect. With the plans, you can then go to solid house manufacturers and get offers. Otherwise, every provider will make a different plan for you and in the end you won’t know which one is cheaper. I can recommend Fred Burger from Wurmberg. He will make you a plan at a fixed price. He planned our house, as well as the neighboring house in [Tiergarten]. Have you already bought the plot?
