Prefab Homes: Modular and Panel Homes

Modular homes. Manufactured homes. Prefab homes. Those words have many connotations, but “prefab homes” covers the broadest range of houses that are built — at least partially — somewhere other than the house’s actual site. Just about any construction style can fall into the prefab category, including timber-frame and log-home construction. Structural insulated panels (SIPs) can be incorporated into many prefab building styles.

Certain aspects of prefab houses make them environmentally friendly: With proper planning, fewer materials are wasted by manufacturing many similar houses in one factory, and leftover pieces are more likely to be used instead of going to landfills. Shipping modules to the building site uses significant amounts of energy, but if the materials are not partially assembled prior to arriving at the building site, they need to be shipped to the site, too (unless wood, rock or earth from local sources are available).

Prefab includes kits for do-it-yourselfers, but frequently contractors complete a prefab house on the building site. So if you find a style you like, you can hire someone to complete the project for you.

Two popular types of prefab homes are modular homes and panelized (panel) homes. Both of these methods produce traditional styles of houses. Finish work (usually including drywall and trim) is completed after the main structure is assembled and passes inspection. In most places, prefab houses must be approved by a local building inspector while the plumbing and wiring is still visible in the walls and after the house is finished.

Modular Homes

Putting together a modular home is a bit like stacking toy building blocks — but more complicated. Depending on the design of the home and the distance from the manufacturer to the building site, each “block” may be an entire house, a room, groups of rooms or only a portion of a room.

MiniHome offers several models of green modular houses. These units include solar panels, and the company avoids using toxic chemicals in any of the construction materials. No part of the house is vinyl, which can produce gasses that may cause health problems. And the only material that has formaldehyde in it is the insulation in the SIPs, which is sealed from interior spaces, so off-gassing should not be a concern.

I love the idea of a prefab home. If someone could give me a website that is user friendly. I live in North Georgia,(not the the mountains).

We live in a prefab house made of high density precast concrete panels. Each panel is 1 meter square and about 1.5 inches thick. They weigh about 150 lb each. We are not in an area that has ANY seriouis storms or temperature extremes. Constuction is foated on a thick pad of reinforced concrete. This form of construction is flexible so is very seismic-resistant. Wh have been in the house during 2 earthquakes. The floor moves, sure but a chain lamp hanging from the high ceiling didn't move at all. COnstruction time was unbelievable. Our house is about 1500 sgft. The house came on Thursday in 3 trucks, construction started Friday morning and was finished by noon Sunday. Complete with Roof, door, windows and a patio with a railing
