In the high-tech approach known as panelized construction, pre-engineered wall sections are produced for a new home in factory-controlled conditions, then shipped complete to the building site for final construction. A panelized home can be weather tight in just a few days.

Unlike mobile homes, leading panelized home manufacturers {such as Harvest Homes} offer tremendous flexibility in design, and their resellers can provide any amenities desired in a new home.

Some panelized manufacturers work through networks of general contractors (professional home builders such as Arcanna Homes).

Pre-building roof and floor trusses in a factory is the most common application of panelized construction in home building today. But recently, the National Association of Home Builders reported that complete home panelization is the fastest growing segment of residential new construction.

“	Pre-building roof and floor trusses in a factory is the most common application of panelized construction in home building today.”

Built with the aid of cutting-edge automation and in factory-perfect conditions, complete exterior and interior wall panels, trusses, decking, etc. are loaded onto panelized manufacturers' trucks and delivered to the homesite. Materials are marked at the factory with a code to eliminate any confusion at the jobsite (i.e., wall "A-1" joins wall "A-2".)

For some panelized manufacturers, their involvement in the construction of the home is finished when the materials are delivered, with all field work completed by the general contractor. Other panelized manufacturers provide a crane and "set crews" when the materials are delivered to work with the general contractor in getting the home framed in. There are even some panelized manufacturers who will supply all necessary labor to complete the home.
