Barn doors are an awesome option for small homes.

I bought a little 1000 square foot home that had no interior doors. The number of usable square footage in any room is diminished greatly by swing doors. In the case of this 1902 home, the casings are odd sized causing a need for custom frames if standard doors used.

These are easy to paint/install, give back a lot of usable space, versatile, and cost effective. AWESOME++++++

I'm sold and will be using barn doors for many projects going forward.
