Standards and building codes, the same sorts of reasons cars, except for a few visual design points, all have the same basic shape and look. Organizations, as well as home buyers, also look for resaleability and the ability to repurpose spaces — odd, though beautiful buildings are thought to be hard to sell, and specialized spaces are considered long-term detriments. Contemporary architecture is a monument to bureauc…
As someone who is not a car owner I find it striking how functionally blind most people are to the ugliness of cars. Modern cars are designed to look well alone in a vast empty space, and that is how car ads pitch them. But when you see them racked and stacked bumper to bumper like in cities it is shocking just how unsightly they are and just how much space we yield to cars dramatically reducing the livability of the city. People are so functionally blind they can’t even imagine any other way. Surely, you must have cars. The notion that we have chosen to make our cities ugly and unlivable and we could choose otherwise isn’t even conceivable. When people hear I don’t have a car they always assume I rent or borrow one often. They cannot imagine how a family of four can get things done without a car, and literally the “how” question is the one I get most.
Maybe something similar has happened to architecture, where social norms have made it impossible for most to even see a different way. Things are the way they are ostensibly for practical and aesthetic reasons, but none of those practical and aesthetic reasons really stand up under scrutiny because ultimately it is down to fashion.
