Storage, Storage, Storage

Since we are stuck in this too-small house for about four more years (maybe we can push it to 3-1/2 years), I need to come up with storage ideas.  Our house doesn't squeeze all of us in it very well and with everybody's "stuff", it's always cluttered.  I can't stand it.  The house can be clean but not look clean because there is just too much stuff! 

I would love for each child's room to have a wall unit of shelves in different sizes to hold everything - books, bins for smaller items, CD's, sports equipment, toys, etc.  I would also like one in the family room.  I've found a company that will design furniture like this. I wish my budget had a lot more room to spend, spend, spend but after Christmas, I'm just happy to have grocery money!
