Manufacturers are more likely to offer standard designs that are popular and have wide economic and visual appeal than to be creative in their design concepts. Most modular manufacturers have specialized in the design of homes with less than 2,400 square feet of living space. Some manufacturers may do custom design work, but it is far more economical to select from the standard design options. Homes A panelized house is produced in the factory with wall panels 8 feet high and ranging from 4 to 40 feet wide. In most instances, the wall panels are designed to be erected immediately after delivery.
Panelized buildings come in two versions, open wall and closed wall.
Open-wall panels are wall sections containing exterior sheathing only. Plumbing, wiring, insulation, and interior sheathing are installed at the building site. Closed panels are shipped from the factory as complete wall systems with exterior sheathing utilities and interior finish materials already in place. The approval process for panelized homes depends significantly on the type of panels being used. In closed-panel systems, the approval procedure is similar to the modular inspection system.
