Update  Nov. 2019...The dog house has withstood nearly 2 years of the elements. It is well made and solid, however the roof does leak when it rains. I added a plastic cover over the roof and a plastic flap over the doorway. With a cozy dog bed inside, it is still a warm place for one of my cats who prefers to be outside. My 2 small dogs have never been interested  in using the dog house as they like to be inside with me.
Follow up 3/27/18:  Dog house now assembled, looks great out on the deck and very cozy.  This dog house is not water proof but when covered with a sheet of plastic is fine. One of my cats loves to sleep there on the nights he doesn't come indoors.
