What a great concept – also hides the dog bed. Make your own with simple materials. Cut a door on a piece of paneling. Give it a white wash treatment. Add a name plate, trim and use small wood pieces (maybe even paint stirrers) to make shingles. So very cute, but yet hidden away.
Do It And How 
Love the idea of the dog house inside the house so cute only wish now I had stairs lol keep sharing
Saw this in a model home and loved it so I just finished building one for the grandkids to welcome their brand new puppy-he’ll grow into it. I found panelling at Lowes which exactly matches that shown in the picture so, no white-washing required. Also, for the roof I used wooden shims, I used cedar shims for mine.
Awesome!
