Abstract

To provide a building planar shape determination method that can reduce the number of types of structural members that make up a building and that can plan complex planar shapes and various planar shapes, and a building having a planar shape determined by the building planar shape determination method.SOLUTION: A building planar shape determination method includes an arc placement step of placing each of a plurality of first arcs having a first radius, a plurality of second arcs having a second radius smaller than the first radius tangent to the first arcs, a plurality of third arcs having a third radius smaller than the second radius tangent to the first arcs and the second arcs, on a plane with a given scale; and a planar shape determination step of combining at least one straight line of a first straight line that connects the center of the first arc and the center of the second arc, a second straight line that connects the center of the first arc and the center of the third arc, and a third straight line that connects the center of the second arc and the center of the third arc, to determine the outline of the planar shape of the building.SELECTED DRAWING: Figure 1
