Projecting off of the wall, Tier shelving by hivemindesign appears to float. Aluminum tiers are wall-mounted and cantilever out to support the shelving. It comes up to 10' long, in shelf depths of 12, 16, and 24" (for desk use). Custom configurations are also available upon request. We love that the aluminum armature comes in a natural anodized finish or your choice of powder coated colors: orange, white, grey or red.
