Shelter is among the top three basic needs, the other two being food and water.
The basic configuration chosen for the EcoShelter is a hexagon with a central supporting column and compression ring to which are attached long span joists which are supported at the perimeter with weather proof columns. The wall footing is excavated to a depth below the frost line. This depth varies with the geographic location but a minimum of eighteen inches is recommended. This excavation creates a thermal break with the surrounding terrain. The panels are then bonded to each other with the expanding foam.
