We are about to move from our 3/2 rental home to share my dads 3/2 house. So it will feel like our family of six will be in a 2/1 since my dad will get 1/1. I'm nervous but we will be saving money and helping each other out. I plan on buying dressers- tall ones to use high space more. A friend of mine with limited space put a sturdy shelf along the entire room near the ceiling and bought lots of baskets. All the baskets are stuffed- great way to utilize all your space. You just need a chair to get to them and possibly label them all really well. Smaller beds may help, loft furniture or beds with storage drawers underneath. Good luck!
