From early-20th-century Sears Catalog Homes to housing experiments by French modernist Jean Prouvé, prefab construction—that is, assembling a structure from components produced off-site—has had a rich, long history. Today, architects and designers continue to explore how the concept can create cost-efficient and sustainable housing.

Some of these efforts have produced prefab designs that are easy for anyone to configure, customize, and call their own. Without further ado, here are five of the most prefabulous homes you can claim for yourself right now. They come in all shapes and sizes and show just how sophisticated the prefab house has become.

The estimated costs listed below typically do not include extra fees associated with land, site preparation, shipping, and other miscellaneous expenses involved in bringing the project to fruition.
