My grandparent's house nearby Berlin is close to 3000 sq ft. They only built it this large to rent out the second floor.

No garage, a carport is enough for the few times a year someone needs to park a car there.

Bus stops every 90 minutes, so not exactly amazing, but good enough for the occasional trip to the city.

Note that bus service doesn't need lots of tax money to build up infrastructure, so it can be built out into even sparsely populated areas.
