neb: Virtually all of them needed considerable design re-work to make them buildable and/or liveable
*shrug* A client out there saw the plans paid for it to be built, not that that absolves the architect of blame for designing poorly. Regardless, the point is that you shouldn't think of a single architect/designer/builder as the only option, there are plenty of builders who will plan a house better than plenty of architects. And vice versa.
