granny flat(redirected from a granny-flat)
A small house on one's property, separate from the main house, that serves as a permanent home for one's aging parents. Also called a "granny pod" or a "granny pad." With this granny flat, I get to see my family all the time, while still having a place of my own that is easy to maintain. Just don't call me "Granny"!
