Our single family homes are freestanding detached homes with or without garages. They are generally designed for one family, that is, having one kitchen and no easy way to partition the house into multiple living quarters. Istockhouseplans' single family homes range from 512 to 2332 square feet. Smaller homes from 800 square feet and down are considered accessory dwelling units as they are generally small enough to be a secondary dwelling on a property. These smaller homes could certainly be the only dwelling on a property if your zoning code allows.
