We use a 12 X 12 Northern Breeze screen room by Eureka. It has 4 flaps to close it in, or roll them up to use the screens. It comes with three poles to use one flap as an awning
, or buy extra poles if you want more awning
sides. Last winter we spent in the south, it was our living room/dining room. We had the picnic table in it along with 2 chairs, a TV, dorm fridge
, camp storage table, coffee pot & toaster, and an electric heater. Cool days we had the flaps down & heater running, warm days roll up the flaps for the screens. It has an external, aluminum pole frame, easily set up by two people once you figure out the method. Pricey though at about $400, but well worth it for us.
