There are hundreds of modern corporate buildings built that way for essentially aesthetic, rather than lot-space-filling, reasons.
For awhile my small 20-person outfit rented one section of a 3-story 1980s construction building with a very prominent ship’s prow-shaped end. It was in a corporate park of many similar buildings and pointed menacingly towards a nearby freeway. This was in greater St. Louis, MO.
Ref the OP’s statement that the narrow corner offices were good …
For awhile I had our prow-office. it was a PITA since there was a lot of floor space that was a useless shape; no furniture could go there. So despite a huge square footage it was actually a small office usability-wise.
As well it was all surface area. There was one interior wall about 15 feet wide which included a door into the rest of our office space plus two exterior walls each 25 feet wide that met at a point, the prow of the building. Those walls were all windows. One faced more or less East and the other West. Which meant the whole office baked in the summer & froze in the winter.
A conventional 90 degree corner office was *much *nicer.
