I respect and admire what architects and structural engineers do. However, let's not put them on too high a pedestal. Architects design buildings with aesthetics in mind and engineers decide whether or not a certain design is feasible. That is why architects' original plans are often modified. Engineers also tend to look at structural problems from an economic perspective. That is why many houses are built using two by eight joists (ie. seven and a half by one and a half), which in my opinion is inadequate. But, it does meet minimum specs. I believe in over engineering. It causes fewer problems down the road.
The design above looks like a problem waiting to happen. At least based on the information given.
