Nobody cares what happens to the building. When it is also easy for the tenants to change it, they do. The result is a building that is changed a lot, that supports its occupants well, and that is not expensive. It requires structure built to last and a very high finish of skin. It has a sequence of people who care for it extending over generations, especially people who take into account what has gone before.
Architects are part of the problem.
They get rewarded for pictures of buildings, not for functional buildings. Frank Lloyd Wright was noted for the leaky roofs of his buildings. He didn't care about that. As a major propagandist for Fuller domes in my Whole Earth Catalogs , I can report with mixed chagrin and glee that they were a massive, total failure. The angles between the facets could never be sealed successfully.
