    Abstract: A portable or lightweight enclosure has a flexible cover sheet (1) which is anchored to a base (2) or to the ground. A number of flexurally stressed or spring-loaded arched supports (6) are located within the cover sheet, the lower of the supports being free and braced against the inside of the cover sheet (1) by the stressing or loading of the supports so as to maintain the cover sheet in tension. The opposite longitudinal edges (5) of the sheet may be attached to respective longitudinal base members (3) which may be filled with ballast. The lower ends of the arched supports (6) may be interconnected by longitudinal elements (7) through which irrigation water may be supplied.
