Modular building methods and systems using precision machined modular panels. Standard modular panels are used for constructing walls, floor, and roof, with transitions from wall to roof and wall to floor provided by special transition panels. The standard panels include a channel formed configured to receive a flange of a C-channel member. The present method progresses by installation of a foam panel (or stack or row of such panels), followed by installation of a C-channel member, with the flange of such member engaged in the panels, followed by installation of an adjacent row or stack of panels, before installation of the next, adjacent C-channel member. Such alternating placement of panels and frame members eliminates the need for a tape measure, the need for any independent frame for the building, and ensures the walls, floor, and roof are square and plumb, as the precision machined panels ensure these requirements are met.
