Abstract: A structurally integrated shelf and soffit configuration is provided for storage buildings and sheds. A shelf board extends inward and outward across the top wall plate and a soffit board is affixed to the outside underside of said shelf board. The soffit board gives a finished appearance and provides support for the cornice fascia truss. The shelf provides a substantial amount of additional storage area. This configuration provides lateral structural rigidity to withstand the outward pressures exerted by a domed or gambrel roof.
