Panelized systems build flat wall, floor and roof panels in a factory. Panels can leave open, as framing only, or closed, with insulation, sheathing and windows installed. SIPs, a foam core between two structural skins, are a common type. Panels ship far more easily than boxes and allow more design freedom, which is why they suit custom homes and sites far from a module plant. See volumetric vs panelized vs kit-of-parts before you choose.
