that's why i moved to friedrichshain.ere are 70 claims of ownership on this building until 1933, it belonged to polish jews, who were thrown out by the nazis. then it became the property of the german democratic republic, and now the courts are trying to decide to whom they will give it. narrator: friedrichshain, and especially kreuzberg, were expected to become more desirable, even expensive places to live after reunification. but the process putting a city back together again is complex and can be very hard to predict. herb: now with the wall gone, there'll be investment into the city center area. this will bring the two sides together. there'll be speculation, and actually, the less- affluent sections of society will move out, because they will not be able to afford the new rents, which will go up with renovations left and right. and this hasn't happened to the degree that people thought it would. narrator: and as the realities of reunification diverge from expectations, some berliners resent the changes.
