Claim 1

A building, which comprises: (a) a plurality of floor panels each including: (1) an insulative core with upper and lower surfaces, longitudinally-extending opposite side edges, a longitudinally-extending intermediate channel and a layer at said upper surface having an overhang extending beyond said side edges; (2) underlayment placed on said core upper surface; (3) at least a pair of said floor panels adjoining with respective side edges in opposed relation whereby a transition channel is formed between said side edges; (b) a transition joist received in said floor panel transition channel; (c) a pair of corner wall panels each having: (1) a core with inner and outer surfaces; upper, lower and side edges; and a layer at said inner surface with an overhang extending beyond said core edges; and and intermediate channel extending in spaced relation between and parallel to said side edges; (2) an intermediate stud located in said intermediate channel; (3) an interior sheathing member attached to said core inner surface over said layer; (4) an exterior sheathing member attached to said core outer surface and having an overhang extending beyond said core edges; (5) a top plate channel formed by said core upper edge, said core layer overhang and said outer sheathing member overhang; (6) a top plate positioned in said top plate channel; (7) a bottom plate channel formed by said core lower edge, said core layer overhang and said outer sheathing member overhang; (8) a bottom plate positioned in said bottom plate channel and attached to said underlayment; (9) a wall transition channel formed by a respective core side edge, core layer overhang and outer sheathing member overhang; (10) an edge stud channel formed by the other of said core side edges, said core layer overhang and said outer sheathing overhang; (11) an edge stud positioned in said edge stud channel; and (12) a corner stud attached to said edge stud and said outer sheathing member overhang; (d) said edge studs and said corner studs forming a vertical corner passage with said corner wall panels being connected together; (e) a corner core member extending through said corner passage; (f) a plurality of wall panels each having: (1) a core with inner and outer surfaces; upper, lower and side edges; and a layer at said inner surface and having an overhang extending beyond said core edges; (2) an interior sheathing member applied to said core inner surface over said layer; (3) an exterior sheathing member applied to said core outer surface and having an overhang extending beyond said core edges; (4) a top plate channel formed by said core upper edge, said core layer overhang and said outer sheathing member overhang; (5) a top plate positioned in said top plate channel; (6) a bottom plate channel formed by said core lower edge, said core layer overhang and said outer sheathing member overhang; (7) a bottom plate positioned in said bottom plate channel; and (8) a pair of wall transition channels each formed by a respective core side edge, core layer overhang and outer sheathing member overhang; (g) a plurality of said wall panels being attached in adjoining relationship with said transition channels in opposed relationship and respective said core layers and outer sheathing members in abutting relationship and forming butt joints therebetween; (h) a plurality of transition studs each positioned in a respective pair of opposing transition channels; (i) at least one of said panels comprising a door panel with a transom section and a pair of jamb sections, said sections defining a door opening; (j) at least one of said panels comprising a window panel with upper and lower transom sections and a pair of jamb sections, said sections defining a window opening; (k) a plurality of roof panels each including: (1) an insulative core with upper and lower surfaces, a pair of side edges and a layer at said lower surface and having an overhang extending beyond said side edges; (2) an upper sheathing member attached to said upper core surface and having an overhang extending beyond said core side edges; (3) a lower sheathing member applied to said core lower surface over said layer; (4) a pair of roof panel transition channels formed by said core side edges, said layer overhang and said upper sheathing member overhang; (l) a pair of said roof panels positioned together in adjoining relation with respective transition channels thereof positioned in opposed relation: and (m) a transition rafter positioned in said opposed transition channels.
