Calculation of a prefabricated house

The windows are arranged arbitrarily, aren't they. And I'm very surprised that the technical room is allowed on the building boundary. There are still a few levels between the Energy Saving Ordinance and the Passive House, and just because it complies with the Energy Saving Ordinance, you still get subsidies from BAFA. For heating, ventilation, energy consultants, etc.

Windows are arranged deliberately - or have we overlooked something? Please keep in mind that you are looking at the entire house (2 semi-detached houses) and you see the northeast side. At the gable, you can see 2 entrance doors in the middle (2 residential units per semi-detached house). The technical room on the boundary is not a problem as long as it does not contain any combustion sources (oil, gas, pellets ...) That's true, subsidies are of course also available for a building according to the Energy Saving Ordinance. It's just significantly less than the overall package from BAFA, KfW, Progress NRW, etc. if you build conceptually advantageous (regarding subsidies).

Where can you get a 6x9 m² garage for around 16 TEUR? I would order two right away.
