One of the most popular addresses in Copenhagen is the small village in Osterbro, called the Potato Rows. Consisting of 480 small three story brick houses, build in 1873 by a group of doctors and architects, who have had enough of the unsanitary living conditions offered to the hard working men and their families. The Potato Rows were simple and affordable (at the time), and the elite looked down upon this pitiful arrangement.
Ironically these days the elite are the only ones who can afford to live here. Politicians, filmmakers and wealthy hippies occupy the tiny houses, that are among the most expensive real estate in Copenhagen. And even if the picturesque little homes may look like dolls houses, you are not invited to play.
One of my favorite details: the built in drainpipes.
