News about the health and beauty of the natural world that sustains us.
Below is a listing of companies that offer green dwellings in the form of modular, prefab/manufactured, compact and/or mobile structures. These days, there are many such options available that are not only green, but also beautiful, well-made, and often low-cost. Some of these structures are homes or cabins/cottages, while others can be used as an addition, a backyard studio, office, in-law unit/guest house, or some other type of “accessory dwelling unit” or out-building.
They come in a wide range of sizes, from teeny-tiny one-room spaces (e.g., 100 sq. ft.) and small units (see the Tiny/Compact Structures section below) to conventionally sized homes. They are also available in a wide variety of styles; some have traditional designs, while others have a very modern look. Some are available as plans and/or DIY kits, and others have designated builders. Many can be modified or customized.
Prefab (factory-built) homes have many benefits. They can be built more efficiently (e.g., less material waste), more quickly, with more precision and durability (i.e., higher quality), and they typically have more predictable costs (and often cost less) than site-built homes.
The levels of greenness vary among the following options, but all of them tout some green features.
This is not a comprehensive listing; there are many other companies that make similar types of green structures. I’ve provided links below to other directories that list additional options. If you know of another green modular, prefab, mobile, or small home designer or manufacturer that you would recommend, please share it in the Comments.
Note: The asterisk (*) shown after certain listings indicates that those companies seem to offer at least one low-cost/affordable option. Some of the other companies might also offer such options, but specific pricing isn’t available on all of the websites; in some cases, one must contact the company for pricing information.
