ᐅ General Contractor in the Munich Area or Prefabricated House?

Hello everyone,

Thank you for welcoming me to the housebuilding forum.
My partner and I would like to build a single-family home in the Bauhaus style near Munich. Since we want a high proportion of glass surfaces as well as large rooms on the ground floor with a ceiling height of 3.50 m (11.5 ft), we don’t fit the standard offerings of prefab home suppliers. None of their predefined floor plans suit us. But of course, according to the sales representatives, they can also build custom designs.
We are just a bit concerned that the costs could get out of control since prefab home companies benefit from economies of scale. Also, with our ceiling height, we cannot use standard windows, sliding doors, interior doors, blinds, etc.

This raises the question of whether it might be better to build with a general contractor using traditional construction methods.
However, general contractors in the Munich area have such poor reviews. I have read here in the forum that it only makes sense to work with a general contractor if they are located near the building site. Do you have any advice or can you recommend a general contractor?

Thank you very much for your tips.
