• common rafters extend at right angles from the plate to the ridge
• hip rafters are laid diagonally from the corners of a plate to the rafter
• valley rafter doesn't extend from the plate or girts to the ridge
• jack rafters is the frame between the hip rafter and the grit
• fascia board covers the rafter end enclosing the overhang
• purlins are horizontal structure member which hold rafters together
• column footing is a reinforced concrete block, setting up under the earth with a calculated depth
• wall footing - a continuous strip of concrete that serves to spread the weight of a load-bearing

• spread foundation - it is a shallow foundation which supports the column and walls
• pier foundation - is one where the load is distributed into soil by slender vertical members
• slab foundation - is a soil slab of concrete poured directly on the ground with footings placed where extra support needed
• t-foundation - consist of a footing upon which is placed a concrete wall or concrete block wall forming an inverted t
• mat foundation - assembles a mat in that the foundation is spread over the entire are of a floor building
• footing - is a portion of the foundation of a structure which directly distributes the weight of the building over large area
