REGIONAL COOPERATION IN DESIGN, CONSTRUCTION, AND MANAGEMENT OF WOODEN PUBLIC FACILITIES (PART 1) : COMPARISON OF THE THREE-DIMENSIONAL TIMBER TRUSS IN OGUNI TOWN AND THE RECIPROCAL FRAME IN SEIWA VILLAGE

This study investigates how regional cooperation has supported the sustainability of timber construction in Oguni town and Seiwa village. Despite geographic proximity, these two communities have developed distinct cooperative relationships due to differing fiscal capacities and industrial structures. The three-dimensional timber truss and the reciprocal frame, remain important regional assets, made possible by the ongoing involvement of diverse local positions. The research analyzes the roles of local governments, timber constructors, regional organizations, architects, and engineers across all phases. It aims to clarify how socio-economic conditions shaped the nature of cooperation and how these efforts contributed to sustaining timber architecture.
