Abstract
Abstract A concentric building including a foundation; a first substantially circular platform serving as a lower floor resting upon the foundation; at least one second substantially circular platform smaller in diameter than, and concentric with the first platform, the second platform serving as an upper floor. A plurality of vertically oriented poles are secured between the first and second platforms, and positioned to rigidly hold the second platform above the first platform. A lower wall is attached to the circumference of, and slopes outwardly away from the first platform. At least one upper wall is attached to the circumference of, and slopes outwardly away from the second platform. First and second tension cables are clamped around the uppermost outer perimeters of the lower and upper walls, respectively, for retaining the walls in an upright position. A roof is secured to the top edges of the lower and upper walls, the upper portion of the roof being truncated to provide a skylight. A hatchway is provided in the upper platform as an access means between the lower and upper platforms; and a doorway is provided in the lower wall.
