Ned there was no restrictions on my design.
There were restrictions on my implementation.
So you designed a 20 lane interchange but implemented a 2 lane one; you designed a 5,000 sq ft kosher kitchen but implemented a 100 sq ft one; you designed a 1 story 1500 sq ft rancher but implemented a 4,000 sq ft 3 story home?
It still smells like nonsense. And it is very, very rare that budget is not a constraint. It maybe that it is not the tightest constraint in which case it is not a "problem".
If you design without considerations of constraints then I don't want to drive on your interchanges, use your kitchens or live in your houses.
