The design and composition methods for wooden dome are described. Wooden spheric dome is transformed into spherical polygon in order to put standard sized lumbers to use. The surface of spherical polygon is replaced with a combination of units, which are consisted of lumbers and shaped six-pointed star. Each unit has wedges, which keep the adhesive angle among units, on its angular points. And the wooden dome is composed of units and wedges by adhesives. The coefficient of construction availability is devised for checking up on measurements of lumbers and rise-to-span ratio of wooden dome in the range of construction availability. It was found that the structural performance of wooden dome is not deteriorated with constructional convenience in the coefficient of construction availability, from 0 to 0.9.
