Single family cedar birdhouse with tin roof from a 100+ year old Franklin County Missouri barn.  Easy clean out.  Some have an oak perch, others have a deep set entryway to keep out predatory birds.
Dimensions vary by house:   average size 10-12 inches tall x 6 inches wide x 6 inches deep - 1 1/2 inch hole.  Perfect for bluebirds.
Each one varies so photo may not depict the exact design.
