Abstract: A building is constructed employing a base plate adapter mounted by a base plate to the exposed end of a rod imbedded in a concrete pad. The base plate adapter has upright sidewalls enclosing a first insulated wall panel. The next upper wall panel is connected to the first wall panel by interlocking fasteners. Comer connectors have first and second U-shaped brackets enclosing a side portion of a wall panel and each bracket pivots with respect to each other. A roof connector joins a top portion of an insulated wall panel to a roof panel. The connector pivots so that the roof panel can be adjusted with respect to the wall panel until a final fixed position is achieved. A roof cap connector joins the top portion of meeting roof panels. The connector pivots until a final fixed position is achieved.
