What is the most important/fundamental question about the floor plan summarized in 130 characters?

Hello, why do you want to build with an [Einliegerwohnung]?

Should primarily serve as a real estate investment (rental income). Many interns and working students rent here.

only the quick (must go) my idea for the OG

..and then only a sliding door to the living room? Drunks at the party who get the door wrong, stagger into the living room or have sex in the guest room? Or those who go upstairs to the toilet (because downstairs is currently occupied)...

I call that a granny flat with family connection

How about a second door that allows for a vestibule with its own exit to the basement?

I don't understand that either, can the tenant access your area?

Best regards
Sabine
