Our Row House Birdhouse has three separate nest boxes each accessible by a single 1 1/4" hole. It's fully functional with back wall cleanouts, drainage, ventilation and unpainted interiors. It's as stylish and desirable as the full size human version, a staple of urban dwellings around the world. Likely inhabitants may include wrens, chickadees and nuthatches. The instantly recognizable wooden water atop the row house is designed as a hanging bracket. Item Dimension: 11. 25" X 17" X 5. 625"
