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.
