All year round patio to sit, eat, cook

Hi, I have an enclosed patio (two sides attached to the house) which needs renovation. I decided to tear it down and build from scratch. What's stopping me (beside other builds my wife requests 😆 ) is I have not yet decided what it's gonna look like. I wanna use it to cook (grill/ooni) and to chill. I'd like to have it open in summer and closed in winter (yes, a fireplace will installed).

Anyone that has build something similar, pictures to help me form my ideas will be greatly appreciated!
