We are ready to put a deck or patio on the back of the house. We need to have it wheelchair accessible. We like stamped concrete but are uncertain how or where to place it. The sliding glass doors (which I hope to replace) are 24" from the ground. We have two special needs kids so less maintenace is better. I have not found a composit deck material that I like. I attached a photo, the area is a blank palette. Thanks in advance, busy mom, nurse and wife in southeastern PA
