Modular Housing: Nice Designs, Neat Installations--and Affordable Prices
Whether you are a first time buyer looking for an affordable home, a homeowner who wants to trade up, or an almost-retired builder who just doesn't want to deal with all the hassles of running an entire construction company, you should consider the advantages of modular housing.
Modular homes, also known as factory-built homes, are available as customized houses that look like site-built structures. The houses, delivered to a site as modules, are assembled quickly, saving time, money, and aggravation. They are no longer just the simple one-story rectangles that characterized early modular homes. If money is a factor you can still buy a standard design, but you can also purchase a more elaborate home, designed by your favorite architect. If you are a builder or developer who is tired of the intense dynamics of site building, you will find the reduced demands of installing modular homes an attractive way to stay in the homebuilding industry while reducing your stress.
Advantages of Modular Housing
The scale and repetition that characterize many multifamily buildings lends itself to an automated solution, especially in areas located near factories. Modular multiple dwellings can usually be delivered and installed for less than $50/sf.
Limitations of Modular Housing
Modular building does not lend itself to large clear spans; however, this is not a problem for most homes. The limit is about 20 feet due to the need to provide supporting walls for shipping. Also, some modular manufacturers use up to 30 percent more lumber than site-built structures to ensure strength and complete the six-sided boxes required for shipping.
In addition, cranes must be used on-site to offload the sections and place them on the foundation. Cranes are expensive; so this process must be carefully planned and coordinated.
Although trailers can carry sections up to 64 feet long and 16 feet wide, extra-large sections can be awkward in the factory and may require re-engineering framing, such as changing to 2x12s.
PATH is conducting a field study of modular housing, and has prepared a comparative study of factory and site-built housing. PATH is also sponsoring the 2004 NextGen Demonstration Home, a modular home that will be on display in January 2004 at the International Builders' Show (IBS) in Las Vegas, Nevada.
