I feel like this is one development that will actually follow through with a completed project that more closely resembles the actual rendering. Yes, I do remember a more whimsical sketch early on in the process, but the more recent renderings are not too far off of the original vision.
Would I be correct in saying that the true skill/expertise of an Architectural firm or quality developer should reside in their ability to design something - from the very beginning - that can actually be built as it was originally envisioned without having to repeatedly pare back a design through VE until it only loosely resembles the original design. It would seem that any firm could develop a fanciful design on paper (or CAD) as a way to impress a client. However, a firm that can design something truly impressive - from the very beginning - knowing full well that the design was achievable without excessive coast over-runs, would appear to be a more notable firm.
Maybe the ability could be equated to an engineer being requested to design a bridge that could hold the weight of a 100 locomotives. It would be easy to meet that design criteria if you had an unlimited budget for steel and concrete and no regard for aesthetics but if you were required to meet the same criteria using minimal materials and funds while achieving an award-winning design - that would be an achievement that required a higher degree of skill/expertise.
