For us, the development took over a year. Before that, there was no building permit and without a (timely) building permit, no application for Baukindergeld was possible - with two children, that's not trivial. This case of a trivial single-family house building application, 100% compliant with the legally binding development plan, escalated up to the state Ministry of Construction. After that, we received the building permit. Just in time. Then it took another three quarters of a year until construction power was available in our street. About 11 months after the building permit was granted, construction only began. And now we are literally anxiously waiting until the heat pump arrives. Maybe November 22, maybe May 23. But - to get back on topic - throughout all this, there were no price increases from the general contractor. We are still paying the prices from 11/2020.
