<p>A shelter, especially an animal or farm shelter, includes two sets of overlapping roof frames, one upper set 7 being vertically offset and overlapping the bottom set 8, with the sets of frames being adjacent to but spaced apart from each other to provide a shelter of a required size. Covers 21 and 24 are stretched over the respective frame sets to cover the shelter and provide a gap between the upper and lower covers for ventilation of the shelter. The covers are attached to the frames by attachment lanyards 23, 26 and hooks 22, 25 hooked over the ends of the frames. When required the covers can be removed to allow the area within the shelter to be exposed to the elements.</p> |
