This Architecture by Hector Ruiz-Velazquez is insane! Seriously, what an ingenious use of space. I think the monochromatic, white color scheme keeps it from feeling too crowded and overwhelming. The second floor (can you really call it that?) reminds me of when I was little and we'd go to Costco and I'd imagine climbing way up to the tops of the shelves and building little forts. Silly huh?
