both of those things would be illegal and has nothing to do with what you're talking about.
They're illegal because laws and codes have been enacted by the federal, state and municipal governments specifically to prevent developers from just "doing what they want." It's called codes enforcement.
This happens in neighborhoods and condo buildings too. If you lived in a nice neighborhood, for instance, you might be aware of such ordinances. For example, a homes association may prevent somebody from building, say hypothetically, a cinder block house with a chain link fence around. May look perfectly fine in Afghanistan. Maybe not Leawood.
Well, cities are the same way. Perhaps there's an important district like an arts district, historic district, or cultural district. Say the City wants to protect the integrity of the district so that it maintains its character. (crazy I know). Well, the City may impose restrictions and regulations for future designs so that development doesn't destroy the district's character.
I am perfectly OK with such restrictions. You are apparently not. I just pray that more people in power agree with me than with you. Otherwise, Manhattan could be very similar to Junction City.
