SAVED!
Typical construction methods include 2-by-4 or 2-by-6 wood-framing. Here's a selection of plans that can be built with panelized systems, like expanded polystyrene foam and light gauge steel studs (called the Vitruvian system), or structural insulated panels (SIPs). Such systems are energy-efficient. See the Design Detail Page on each plan for information about the building system.
