We have just gotten a new puppy and I need to build a gate on my second floor deck. He loves to do his business on the deck and not in the yard. I want to build a gate on the deck to keep him in the yard. The gate needs to be 42 inchs high by 33 1/2 inchs wide and was hoping you may have some plans on this which would include the types and amount of lumber used to do the job and what would be the best type of hindges to use.
