Indie Furniture is "a bespoke storage solution consisting of universal furniture joints and customized wood panels." In this case though, the panels are bought/found/cut to size by you (or the carpenter around the corner), to be connected by the provided clamps, standardized to common shelf depths.
To save you some of the calculation legwork, Indie Furniture has developed an online configurator to help you determine the number of clamps you need and how much wood to buy/scavenge—just like the container store, but...indie.
According to Nicola From Bern and Blackyard, the developers of Indie Furniture, this system accomplishes several things at once: in addition to being straight-forward to assemble and highly reconfigurable, shipping only the clamps reduces the furniture's carbon footprint and allows consumers to engage their local manpower—whether that be raw material suppliers or carpenters.
The system is currently on exhibit at the Design Museum London, as part of the Sustainable Futures show, opening today. If you're in London, head over there to take a peek, or look through the detailed and well-illustrated online manual for more information on how it all comes together.
