Inflatable frame is fully covered with elastic material awning and has means for structure dimension change. Inflatable frame and awning have at least one horizontal cut plane dividing the frame and awning at least into two layers. Means for structure dimension change is made as a system of inflatable frame and awning components detachably joined one to another during cooperation thereof. The components are arranged in horizontal plane area and located along the full cut plane perimeter. The fist parts of the components are connected to upper part of lower layer, the second ones are connected to lower parts of upper layer, wherein perimeter of upper part of lower layer and perimeter of lower part of upper layer equal thereto is less or equal to the structure base perimeter.
