I just finished the latest addition to my home dojo. It's two pulleys, spaced five feet apart, placed in a rafter in the garage. A length of rope is run through them with a loop at one end. I use this for leg stretches. Also present, so far, is a heavy bag and a weight bench, as well as an expanse of floor for kata.
