The exterior wall is framed with OSB sheathing and lumber studs. 2x4 blocking is installed as firestopping where the exterior wall and the cathedral ceiling intersect. The cathedral ceiling is created using pitched chord trusses.

Headers require multiply studs for end bearing to support floor and roof loads from stories above. Most builders use two top-plates in wall construction.

Exterior wall sheathing is revealed beneath the gypsum wallboard. In most instances, the sheathing can be installed with its long dimension parallel or perpendicular to the direction of the wall stud.

OSB wall sheathing provides overall stability to wood frame construction.

A long-span header is used to carry load across a complex window design.

Single-family dwellings that are fully sheathed in OSB offer resistance to wind and seismic loads.

Fully sheathed walls of OSB offer resistance to wind and seismic loads.

Many builders choose to fully sheath single family dwellings with OSB to provide structural integrity.

Walls sections for single family construction can be manufactured off-site and transport to the job on flatbed trucks. The wall sections are positioned in a specific order and fastened together. Construction using components is becoming more common.

Pitch chord trusses can be manufactured with raised heels at the bearing point on exterior walls. This allows for the placement of insulation, while maintaining code required attic ventilations.

Pitched chord roof trusses are sheathed with OSB. Scissor trusses create a cathedral ceiling effect from inside the room.

The few remaining pitch chord roof trusses are lifted into place over the garage.
