seems a bit timid with that residential blank wall behind it. Seems like they could put a 5 or 6 story building there without disturbing the neighbors one bit.
The owners of the property my not want a 5 or 6 story building or have the money to do so. Just because it can be done doesn’t necessarily work for everyone.
