Low-cost, semi-permanent rigid-wall modular Yurt-type, peaked-roof structures, polygonally “round” (in plan view), made of modular, light-weight, water-proof cellular extruded plastic sheet panels that are easily portable, quickly erectable and dismountable, having a wide variety of uses. The modular panels are easily die-cut from any water-resistant, non-metallic, rigid material, preferably an extruded plastic, such as a polyolefin polymer. Few panel configurations are needed to form all the structural elements. In addition, multiple similar modular structures may be grouped to form larger compound structures with individual ones of the Yurts being assigned to individual persons or dedicated work space usages: disaster shelters, sleeping, gathering, storage, hygiene, medical treatment, schooling, entertainment, goods manufacture, cooking, eating, herding, etc. The key principles of the inventive technology are equally applicable to both single-walled and double-walled structures, the latter of which provide spaces between the walls for inter-panel insulation for cold-weather environments and passive ventilation in hot environments.
