This bb house was made as an abbreviated attempt to imitate someone else's fine design. White pine, no finish. Turns out that the birds prefer that. I put a door hinge on the top. Water doesn't seem to get down in because of the slight overhang of the roof. Its been there for 8 years and needs replacement. I'll duplicate the design. I wrapped the roof with some brass sheet I had. Its pretty crude, but wildlife lives in rather crude abodes.I need some also...and looking specifically for a bluebird house plan as well. Looked on the net, ust wanted to see what the creative bunch has...thanks!!
