When you can't spread out, spread up! Look for stacking, wall hung or bookcase storage - ikea is always a good source, as is craigslist this time of year, since students have just moved. If you can only afford open storage, look towards matching containers within, or fabric covers velcroed over..

Narrow your colour selection in each room where storage takes over, to cheat the look of more space. Painting storage and walls the same colour will also help. Best of luck with your project.
