Abstract
Abstract A geodesic dome-type building structure includes a central top hexagon panel unit surrounded by alternate pentagon and trapezoid units defining a roof structure supported on vertically extending walls formed of vertical rectangular panels separated by pairs of quadrilateral panels. This structure forms a self supporting building with expanses of vertical rectangular walls for hanging of conventional doors and other similar building units as well as interfacing with conventional rectangular walled three dimensional building structures.
