Design should include freehand sketches and consultation of architectural product catalogs. The designer must consider building code guidelines and make decisions regarding
- footing and wall size for the foundation wall
- ceiling height for the crawl space or basement
- floor framing design
- type of subflooring and finished flooring
- wall framing design
- interior wall and ceiling materials
- wall, floor, and roof insulation
- roofing system design, including rafter and ceiling joist construction, truss design, and slopes and pitches
- roofing materials, including types of sheathing and shingles
- cornice and guttering design
- exterior siding materials.
Process/Skill Questions:
- How does a steep roof slope affect water drainage? A shallow slope?
- What considerations should influence the choice and amount of insulation?
- What are some consequences of a poorly designed floor framing in relation to the construction of a structure?
