I recently moved to a German city that, whenever I mention it, is described as “ooh it’s such a beautiful city!” because it wasn’t bombed to shreds in the war and a lot of buildings are from 1900ish and older.
Honestly I would rather prefer to live in a building like the post. The apartments often are cut more efficiently and fit better for a family. Yeah, the outside isn’t as appealing as around here but I don’t live on the outside of my house, I live inside of it, so I barely care about its outsides. The other side effect of eastern blocks is that the density per square km is amazingly high. This also leads to supermarkets etc being everywhere. (I am, of course, making generalizations here.)
Of course I need to say that the energy efficiency in old eastern block houses is also awful.
But I don’t want to bash the 1900s houses too much. At least they have 4-5 levels. That’s still better than single family homes in the middle of a city (talking about you, pipe smoking guy in the middle of Sendling).
Painting the outside different colors would help the appeal of the buildings, at the cost of whatever thermal efficiency the color white provides
Of course I need to say that the energy efficiency in old eastern block houses is also awful.
It usually can be improved with additional insulation.
We live in a house from 1900 and thanks to a lot of work our apartment has the energy efficiency grade A to B. We will also get a heat pump in the next few years. We have PV on the roof (I’m not sure what for right now), our windows are triple glassed and we have two heat exchangers thingy that sucks air from the outside and pushes inside air out. A couple of months ago they also insulated the roof of the basement better.
We are very lucky that the owner is behind all these works. Most aren’t, but it is to show that you’re absolutely right and how much can be done and improved. (However, I still don’t like the cut of the apartment or not having an elevator/barrier free access to the basement. And the bugs.)
