Concept:
My idea with this is to turn the barracks building into an apartment complex. Each small room would be equivalent to a 1c house (Not upgradeable at all, no greenhouse, no storage increases). Instead of purchasing these "houses" normally you'd rent them instead. So it'd be more like a weekly payment for the house.
Pros:
Close storage to square for all new people and veterans alike.
Easier to find available units than finding available houses
