Abstract: A building structure is disclosed which comprises a central core with a plurality of habitable areas extending radially outwardly therefrom in the manner of spokes of a wheel. Glassed-in walls extend between the spokes to provide a plurality of climate-controlled atria. Facades on the sides of the spokes adjoining the atria also have glassed-in walls providing a view of both the atria and the outdoors from within the habitable areas. The horizontal section of the building may be circular, oblong or polygonal.

Abstract: A shelter comprises at least two sets of arched support ribs with the support ribs of each set being pivoted by the adjacent ends thereof upon a common locus and having one set of support ribs over spanning the other set at an angle to each other. Some of the intersections are secured together and a flexible cover is secured over the support ribs. By situating the end support ribs in a plane at an angle to the supporting surface upon which the shelter is erected, substantially triangular openings are defined which can be used for access if required.
