Who would voluntarily build 1.5 floors when two are allowed?
.
Why not?
2VG have the sole advantage of creating as much living space as possible on a small area.
“At some point in this time the city villa and a general contractor” came along who mocked the roof slopes and the space underneath, which resulted in no one appreciating these roofs anymore. If you apply some brains to building a gable roof or a single-story building, have a bit more building space available than in and around Munich or so, “charming living” can come out of it, and far more rooms with a positive aura than the rooms in the upper floor of a city villa.
As already said: think first before building and don’t build 100% in height and width right away, otherwise more city villas would be built even with half a floor in the roof [emoji6]
