We also had conversations with Keitel-Haus and I liked their wall construction. We definitely wanted an offer from Hacke as well, but somehow they have a communication problem. The saleswoman in the model home park was very terse and somewhat condescending. In our town, Hacke is selling plots of land and we called the responsible man several times. At first, we didn't receive any documents, then he stood us up for the appointment, then he wanted to call us back. Well - we're still waiting for that callback today. We also didn’t have good experiences with local home builders: appointment canceled, kicked out of the office because we didn’t like the initial design, etc. Ultimately, we decided on a solid house manufacturer from East Germany and are very satisfied so far. We planned completely freely with an architect from our area.
