- providing a preformed window perimeter included in one wall structure of the plurality of wall structures which includes a sill panel spaced apart from a header panel and positioning both the sill panel and the header panel between a pair of capped U blocks of the first portion to form a perimeter for a window opening configured to receive a window frame and a window, wherein each capped U block of the pair of capped U blocks includes the void with rebar therein as well as a plurality of recesses on a side of each capped U block of the pair of capped U blocks forming a portion of the perimeter, the plurality of recesses on the side connecting to the void in each capped U block and configured to receive at least one of concrete and cementitious material therein;
- providing a preformed outer door perimeter included in one wall structure of the plurality of wall structures which includes a header panel positioned between a pair of capped U blocks of the first portion of the plurality of U blocks to form the perimeter for an outer door opening configured to receive an outer door frame and an outer door, wherein each capped U block of the pair of capped U blocks of the first portion includes a void therein as well as a plurality of recesses on a side of each capped U block of the pair of capped U blocks forming a portion of the perimeter, the plurality of recesses on the side connecting to the void in each capped U block and configured to receive the at least a portion of the at least one of concrete and cementitious material therein;
- providing the roof structure, including at least one pair of opposing end wall structures, each end wall structure including at least one end wall beam which is positioned above and connected via the adhesive to at least one wall structure of the plurality of wall structures, the at least one end wall beam formed from one or more U blocks having rebar and the at least one of concrete or a cementitious material positioned in the recess therein, a roof apex beam extending from an apex of each end wall structure;
- providing a plurality of support brackets connected to at least one of the roof apex beam and at least one wall bond beam,
- connecting the plurality of support brackets in opposing pairs on the roof apex beam and the at least one wall bond beam, respectively;
- providing a plurality of roof supports and positioning the plurality of roof supports, such that each opposing pair of support brackets carries one roof support of the plurality of roof supports;
- providing a plurality of roof panels formed from expanded polystyrene, each roof panel of the plurality of roof panels connected to at least one of a) each other via the adhesive, b) one U block of the third portion, and c) at least one connector, wherein each roof panel is carried by at least one support of the roof structure and forms a plurality of roof panel structures when connected to at least one of a) a plurality of roof panels connect to each other and connectable to the roof structure, b) at least one U block of the third portion connectable to the roof structure, and c) at least one connector carrying a roof panel connectable to the roof structure;
- providing rebar to each U block of the third portion of the plurality of U blocks and connecting rebar extending from each U block of the first portion to one end of the rebar in each U block of the third portion, and connecting an opposite end of the rebar in the third portion to rebar in the roof structure;
