Mother Earth News has plans for building a built-in bed. I have yet to find a good set of plans for the famed Murphy bed; has anybody else?

Build one of these, put it somewhere semi-private in your home, and rent it to a community-minded friend (or random Craigslister) to decrease your energy footprint by increasing your denominator for home energy use. It’s up to you whether you make “help on projects” a condition of the rental:)
