I recently installed some custom shelves for Mr. C, who is moving into a new 1,600 SF house. The house has limited storage, so with a little creativity we where able to build something which greatly expanded his storage options:
^ Three-foot deep shelves are suspended over the garage door; with a few bins/totes this will be a great place to store items that do not require frequent access.
^ A two-foot deep shelf over the side door provides a large shelf that is more accessible than the one over the garage door.
< Mr C loves to fish, so we incorporated fishing rod storage into a series of shelves on the back wall. The rods can be kept (untangled) off the floor and the whole wall is not lost to simply lining them up in a single row. The corner was left without shelving to allow for a chest freezer (Gotta have somewhere to put all those fish!).
^ A set of very sturdy triangular shelves just inside the door from the kitchen will allow for larger items that may not fit in the pantry (bulk soap, cleaners, etc.).
