You are very right [member=75217]squall_line[/member] proportions are very important. This thing is going into a very large room, where something small (normal) would look out of place. It still looks huge inside of a massive shop though. It's still rather intimidating to stand in front of it. That lower shelf, in the center section, is 70" off of the floor and like I said before, it goes onto a run of cabinets. Those are already in place.
[member=66966]jonnyrocket[/member] it's all particleboard with laminate covering. The narrow shelves are 1" thick, with a 2" White Oak front edge, stained to match. The wider ones are 2" thick, with the same edge.
The whole thing falls into the category of stupid-heavy. I'm glad I have nothing to do with the install.
