I will be doing some yard renovations when money allow (which wont be soon though). Things I would like to add is a small grain mill with water wheel (fell in love with them when I did a trip to Missouri as a kid and saw a few). It would be located on a small stream (man maid) flowing into a pond. I would recirculate the water for the river flow and if possible use the water wheel to help generate some of the electricity for the pond pump. Also I would like to add a wishing well into the landscape.
What kinds of things would you add to your garden/yard non plant wise?
