I wanted to see what I could do with the smallest lot possible (10x10) and this is what I came up with. It's not much, but it's a nice little starter home for one Sim or even a couple (that doesn't plan on having any kids, lol).
1 bedroom, 1.5 bath & office.
Lot size: 10x10
*House contains custom content and Sims 3 Store items
