A fully framed Annexe has extra poles which run from the caravan out to the vertical poles at the walls. There are also poles placed horizontally between the vertical poles. This allows the walls of the Annexe to be made taut for the more permanant situations. Zipped Off Walls
Besides having zips on the corners, zips may be included on the top of the side walls. These zips allow the walls to be completely removed, leaving the Annexe roof as a varanda.
Draft Skirt The draft skirt is attached to the caravan on the lower edge and encloses the area between the bottom of the van and the ground. The draft skirt gives privacy and stops drafts from entering the annexe from under and across the caravan.
