This is EXACTLY what I did…Build her an outdoor shed with power and water for all her gardening tools. You'll probably get the husband-of-the-year award AND you'll have room for your lathe.
(This is so easy.)
Trust me, if I can do it so can you!! And I built mine without any plans!! And she helped!!!Myself, and construction do not have a good working relationship. I can work on cars, I can deal with bodies, parts of bodies, and fix things around the house. Me, and wood don't get along.
