1. A method of constructing a building including the steps of:
(a) providing a prefabricated building truss comprising:
i. a roof truss assembly including at least one rafter and at least one joist;
ii. at least two opposed building room-height vertical supports which are bridged by the roof truss assembly at roof level; and
iii. a horizontal structural floor element extending between and connected to the vertical supports at floor level, the structural floor element being configured to engage a building foundation system;
(b) providing the foundation system at ground level;
(c) mounting a plurality of the prefabricated building trusses in parallel and spaced apart in the longitudinal direction;
(d) linking the plurality of prefabricated building trusses by interconnect beams to form a structural floor which engages the foundation system;
(e) applying panels to form at least internal wall, floor and ceiling surfaces; and
(f) providing utility services and performing finishing tasks,
wherein the roof truss assembly is integrated with the vertical supports by a rafter engaging at least one vertical strut of each opposed vertical support; and wherein each vertical support comprises at least two vertical struts in which outer struts are lower in height than inner struts, and the roof truss assembly rafters span the vertical support struts, thereby providing additional bracing strength to the vertical supports and also integrating the roof truss assembly with the vertical supports to form an envelope together with the structural floor; and wherein the roof truss assembly comprises a structural horizontal roof tie which comprises the at least one joist, and interconnects opposed rafters of the roof truss assembly, and said rafters are connected to the vertical supports; and wherein the roof truss assembly comprises at least one brace, parallel to a rafter, and connecting a vertical support to the horizontal tie; and wherein the horizontal tie comprises at least two parallel horizontal tie members and a support structure between the horizontal tie members; and wherein the horizontal tie support structure comprises a plurality of load-bearing braces joining the horizontal tie members.
