Little Rascal and Freelancer's Fashionblog have given me Ladderax fever. Ladderax is a British-manufactured mid-century shelving system, named for the metal or wood "ladders" that make up the sides of the shelves. Then a combination of shelves and/or desks and storage units can be attached.
It is gorgeous but quite difficult and expensive to find in the states. I'm afraid that obtaining the shelving for myself will remain a dream for the time being. If you happen to have a tip for where to find Ladderax in the US, I would be very much appreciative.
