Forget doublewides and trailer parks.

Forget doublewides and trailer parks. Prefabricated homes have gone upscale with modernist designs and luxe amenities -- for up to 30% of the cost of a custom-built home. Think Frank Lloyd Wright meets Ikea.

Prefabs are becoming a popular choice among home owners aiming to keep the lid on building costs for second homes and weekend retreats, but who still want distinctive design and special touches. What's more, prefabs go up one-third faster than custom-built homes because factory production faces none of the 11th-hour changes in the availability of labor, supplies and good weather that custom builders face. You can learn about the ins and outs of buying a prefabricated house by reading Fabulous Prefabs (opens in new tab) from the July issue of Kiplinger's Personal Finance. We also compiled a photo gallery of selected models by top architecture firms. (Note that most of the firms that design these homes offer models in other shapes and sizes and also build custom homes.) So shake off any notions you may already have, and take a look at these fabulous prefabs.
