I'm an architecture student myself. Reading Zach's instagram posts is giving me too many flashbacks to sitting in on 3+ hour critiques while listening to other students as they try to drum up an explanation for their projects. On one hand, I can appreciate the justification for such a simple design. There's a lot of thought that goes into the spatial qualities of the building. On the other hand, it sounds like total BS - trying to make something basic sound more interesting than it actually is. Something I feel happens way too often with modern design. Architects design buildings like this for other architects. "Less is more" is a major design principle in many of the buildings we see built today, and while it can work at times, the average tourist is not going to care about the symbolism behind the flooring or the parti of the building itself. I think it's absolutely wonderful that they're considering such small details, but they ruin any chance of people taking it seriously by slapping Mickey Mouse all over the damn thing.
In short, it's a nice, sophisticated design that I believe works for a modern day EPCOT. I think it's a much better use of the space than Mouse Gear ever was. As much as I loved Mouse Gear, I always thought it felt out of place given its location. This was a step in the right direction, but at the end of the day it's just another copy and paste Disney gift shop. The art looks nice, but from what we've seen there's nothing really bold or iconic about it. They've clearly put a lot of thought into the design, it's just a shame that it likely won't show in the final product.
