Abstract: A shelter construction kit includes at least six composite panels which are identical prior to the positioning of access openings. Each of the six composite panels has a first side edge having an integrally formed male coupling and a second side edge having an integrally formed female coupling. Each of the first side edge and the second side edge extend outwardly at 45 degrees from the first flat face to the second flat face. When the first side edge of one panel is coupled to the second side edge of another panel in a first orientation the coupled panels are on a common plane. When the first side edge of one panel is inverted and coupled to the second side edge of another panel in a second orientation the coupled panels form a 90 degree corner. Roof/wall interface brackets are provided to secure the roof panels in place. Assembly instructions are provided describing how to couple the panels.
