I would never have built like that. I wanted a house so that I also have a garden. And my peace. But in a flat I have more peace than on those towels. Around the corner from us there's also an area (but with strict design regulations), where you can look through one house from the street into the kitchen of the one behind it. Because they are also built so close together. For such tightness I don't need a house... creepy.
We were also lucky with our 460sqm in the new development area, most plots around here are much smaller - although I would have liked to have more but for that I would have had to marry rich.
