The small two-story terraced houses in the Olympic Village are commonly called bungalows. From a definitional standpoint, that’s probably not quite correct, that’s true. But they are easy to google.
These offer a lot of utility in 24 sqm, are very well thought out. Own front door, small kitchen, small bathroom, built-in closets, and on the first floor a balcony and room. I immediately thought of these when reading the thread. They were also very cheap back then, today probably no longer available for 12,000 Marks due to the energy saving regulations.
