If you're looking to get a little more use out of your backyard birdhouse, then you need to check out the Ferma birdhouse. The Ferma birdhouse was designed by Michael Sholk to double as a piece of furniture for its human creators.

Sholk's design reinvents the birdhouse completely, changing it from a little house designed to be hung from a tree to a small abode with slots for poles. The poles are lengthy and use the birdhouses as connectors. Inventive owners can design a shelving structure or table using several Ferma birdhouses. Allowing humans to benefit from having a birdhouse may very well be the perfect way to get more people to start putting up birdhouses in their backyards. At the very least, the Ferma birdhouse will encourage existing birdhouse owners to be more creative.
