Our current house has one walk in close in the master bedroom (good sized), and small regular closets(with those annoying sliding doors that always get off track), in the other 2 bedrooms, and that's it for storage space. No coat closet, linen closets, etc. The kitchen does have a pantry, but small and not walk in. And we have 2 whole drawers in the kitchen! I have had to learn how to use small spaces creatively.
My kids closet was big enough for a wire thng that has 4 shelves(free from my parents who no longer had a use for it), and on the shelves I put dish pans (around $1 ea. at Target), ea shelf could fit 2 dishpans. Then I filled ea dishpan with their books, standing upright, that way they are easy to flip through and see the titles, and easy to put back in. They have a ton of books so this really helped. Next to the wire shelf thingy we have a toy bin, this kept all the toys and books in the closet and freed up more space in the room. I know a lot of people don't like the toy bins, but they worked fine for us, guess my kids have a lot of small toys. (Legos, wooden blocks, little people). The big shelf at the top of the closet could fit 4 huge rubbermaid bins with lids, where I would keep the extra toys. I would rotate the toys every few months with the toys in the bin and they were like new again. The containers were not see through, so my kids would mostly forget there were more toys up there and not nag me about them.
I kept each person's extra sheets and bed linens in under the bed storage boxes under their bed.
Each season I would clean out their drawers and rotate out of season clothes. The out of season clothes that I thought they still might fit into next season, went into their old toy box. I had hated using this big wooden chest as a toy box but it works perfect in the back of my big closet, as clothing storage. In my closet I also kept a wire shelving thing that had sliding drawers, for all of our homeschool stuff we were working on, since we had no extra cabinets or closets for it, or even room for an extra bookcase.
In my kitchen I had a wall organizer that had pockets for scissors, pens, odd and ends, since I couldn't spare a drawer as a junk drawer. I also had a wicker basket on the bottom shelf of my pantry to hold kitchen towels, pot holders, etc. since we didn't have an extra drawer for kitchen linens either.
The thing I am looking forward to most about my new house is all the closets, since I've been there with the limited storage space. Who needs crown molding and corian countertops, it's the extra storage space that got me.
