The Bird Perch Bookshelf from Notus Design is a playful piece of storage. It uses a series of colorful birdhouses (technically a perch I guess since they’re not enclosed) mounted on a stand. It makes a tree-like place to store books or knickknacks. Would look good in a kid’s room or a whimsically decorated home. Contact the designers directly to purchase (no price listed) or head out to your workshop and build your own version.
