Systems and methods are described herein for a panelized building assembly comprising a double skeleton of planar connectors, positioned parallel to and behind the inner and outer building surfaces of panels to be connected. The planar elements may be folded symmetrically about the bisected angle between adjacent surfaces so as to form a coherent and continuous double layer that can, in some cases, offers structural, fire, acoustical and waterproofing performance consistently between various panel. The connectors may extend into the mass of a block of material that forms a continuous edge around the perimeter of the panels, which is bonded continuously to the fiber-reinforced skin of the panel and to the core material that the inner and outer fiber reinforced skins are also continuously bonded to.
