Modular shelves and storage units are appealing since they can so easily be moved, rearranged, and made to fit awkward room layouts (my bedroom and office are in a converted attic with ceilings that slant down, so I know all about trying to furnish awkward spaces!).
While the galvanized steel look might not be for everyone, these industrial cubes offer a lot of storage options.
The cube is the basic building block, and you can get them open or with doors, with or without wheels, and wall-mounted or free-standing. This simple arrangement allows you to build credenzas, book shelves, tv entertainment centers, closet storage units, desk, towers, etc. etc. etc.
Visit the Container Store’s “Galvanized Solutions” section to get an idea for all the uses you can find for these little cubes.
Prices depend on how many cubes you want to get and what you want to make, but examples of some possible systems are a galvanized cube storage table for $164, a bath storage unit for $430, or a complete wine bar setup for $970.
