Ikea Besta units - I love the idea of a complete wall of units.Could be used in any room including a kitchen or playroom. The glossy finish reflects light back into the room and would hide a multitude of clutter.
Custom, built-in mud closet. I don't think you'd lose storage space, but. where do the shoes go? I don't want to have to open the bench and dig every time I go out! maybe change it where the front part of the bench opens instead of the seat part?
DIY: PVC Pipe Shoe Storage - so fun and so simple, could easily spray paint or cover in fabric or paper too. maybe a horizontal layout of two rows or something. I think this would be good for garage "yard shoes" storage
