Pixar had a really cool idea put all of the bathrooms on one side of the building
I'd be interested to know how much they saved on plumbing costs. That seems to me like an architectural decision driven by financial concerns and sold as a benefit. Not that it isn't a benefit, many of the most interesting designs are a consequence of some practical constraint.
Apparently you haven't seen the Pixar buildings; it's pretty clear that little of their design was guided by financial constraints. They are about as far as it's possible to get away from typical cheap office construction.
