Multi-generational house with underground garage for 3 families

If you position yourself cleverly, you can fit at least 6 cars.

... whereby I would like to point out to the readers that (if the access ramp has to overcome a whole floor of height difference) the purely space-related synergy effects compared to single garages are still fully compensated with six parking spaces; including ventilation technology, the breakeven is even around eight parking spaces. Economically, small underground garages are therefore rare and, in connection with the building ground and its price, almost a Munich-and-Berlin-specific phenomenon (in Hamburg and Stuttgart, other geological or topographical aspects come into play). In the flat countryside – hopefully the people of Münster won’t be too offended – a small underground garage is regularly a "luxury". And if I remember correctly, we also discussed the alternative of a carport here.
