I was going through my old photo files today and came across this pic of a salvaged and recycled-material chicken coop that I built about two years ago.
Ultimately someone bought it, but for use as shelter for his dwarf goats! Hey, whatever works….
Anyway, with a little enlarging (note: a front stereo-glass (salvaged) window was later added), this boxy design could make for a very simple playhouse or treehouse/treefort.
Some similar designs (TONS of ’em) also appear/are sketched out in my indie-released book “Humble Homes, Simple Shacks, Cozy Cottages, Ramshackle Retreats, Funky Forts (And Whatever The Heck Else We Could Squeeze In Here” – through Tiny Yellow House Press and available through http://www.relaxshacks.com for $15.95 (includes shipping).
