A Home Fit for a Dog

Without a concern for expense, I would create a home with the same square footage but all on one level, like an American-style ranch home. Having two stories is not a very useful layout for me because I own a dog who is has difficulty with walking and cannot climb stairs. So, I would like to have my own bedroom and study downstairs so that I could be around him all the time, when I am at home. I would also create a custom dog room, with permanent outdoor access and an outdoor dog run, so that he could have an interesting life when I am at work.
