Steve Baczek, a Build Expert, discusses how wall framing relates to the roof framing in a new project. The main hall of the house has 10 ft walls with a vaulted ceiling and scissor trusses. The floor plan features three gables that run front to back and two cross gables connecting them. The roof plan shows the relationship between the walls and trusses, with perpendicular areas creating valleys. The roof design is straightforward for a ranch style house. Understanding how the floor plan connects to the roof plan is essential in designing a functional and structurally sound home.
