A roof truss is made of unitized wooden frame elements comprising a pair of centrally interconnected upper chords which are joined near their outer ends by a horizontal lower chord which is discontinuous near each end thereof. Vertical risers interconnect the lower chord on both sides of each discontinuity with the upper chord to form post-receiving pockets near each end of the lower chord. These pockets are preferably backed up by a prenailed gusset on one side of the truss. This roof truss is combined at the building site with a lower section comprising a floor truss having a vertical wall-forming stud at each end thereof to provide a unitized truss frame.
