Modular building methods and systems using lightweight foam modular panels which are based on fractal geometry. Each panel includes one or more channels formed through the foam body, where the channels are centered between adjacent fractal modules of the overall modular panel. The channels are configured to receive splines (e.g., dimensional lumber) therein. The entire system is based on dimensional lumber sizing. The rectangular panels include a pre-cut slot extending through one face, to the channel, while a score line is formed in the opposite face, aligned with the pre-cut slot of the opposite face. The panels may be easily and quickly cut with a box knife to reduce the number of fractal modules in a given panel, to provide a smaller panel still based on such fractal geometry. Such a cut is made along the score line, where the foam is no more than 2 inches thick.

A shelter includes: at least two side walls; a back wall; and a roof, wherein the side walls, the back wall, and the roof comprise a material that is weatherproof and insulated, and wherein the shelter is collapsible, detachable, and portable. The shelter can also include at least two side walls, wherein an upper end of the at least two side walls conjoin to form a roof. The shelter is lightweight, detachable, and portable. The shelter can be weatherproof and insulated for permanently or temporarily housing people and/or animals. The shelter can be transported to a desired location and assembled on-site with ease. When the use of the shelter is no longer desired, the shelter can be quickly disassembled and transported to another location.

A building block for a modular system for construction of a wall frame, the building block having a frame portion having: a rear exterior side; a front interior side; a top end; a bottom end; a left side; and a right side; a sheathing extending across the rear exterior side; at least a first dowel protrusion or at least a first dowel cutout; at least a first mortise; and at least a first tenon opposite to the at least a first mortise; such that the at a first mortise is capable of associating with a corresponding first tenon of a second building block to create a first mortise and tenon joint; and such that the at least a first tenon is capable of associating with a corresponding first mortise of a third building block to create a second mortise and tenon joint.

A building block includes a plurality of panel elements that are each rotatable relative to each other one of the plurality of panel elements; a connecting pin that passes through and rotatably connects the plurality of panel elements to each other; and a plurality of connectors, each connector rotatably attached to a respective panel element, where each one of the panel elements includes at least on locking feature configured to create a releasably fixed connection between adjacent panel elements.
