When we bought our house 8 years ago I laid down concrete for a deck because I thought it was the cheaper solution and would still allow me to eat outside. But now, I really want to build a deck where part of the patio is. The patio is the entire length of the back of our house but the deck would only be off the back of the dining room where I would put French doors (so not even half the length of the deck.) what is the best way to approach adding a deck?
