Hi, we want to work on our backyard, we have a high grade elevation about 4ft. We have a deck that was made with the house when we moved in its about 4ft high, (from our kitchen sliding door) and we have about 9 stairs going down to the backyard, We are a corner house and just thinking being up so high we would prob be an eye sore, and we wouldnt get privacy? our goal is to be able to enjoy our guests as well as have some solitude. We were thinking 20x21 , we were thinking a deck but with covid19 backup, lumber has gone up 800% from original price, or should we go patio? and what designs if any? Thanks, your advice would be appreciated.
