The New York Times reports:

...the Museum of Modern Art has commissioned five architects to erect their own prefab dwellings in a vacant lot on West 53rd Street, adjacent to the museum. Whittled down from a pool of about 400, the five architects are participating in “Home Delivery: Fabricating the Modern Dwelling,” an exhibition opening in July.

The five, to be announced today by the museum, are KieranTimberlake Associates of Philadelphia; Lawrence Sass of Cambridge, Mass.; Douglas Gauthier and Jeremy Edmiston of Manhattan; Oskar Leo Kaufmann and Albert Rüf of Austria; and Richard Horden of Horden Cherry Lee in London.

The MoMa site fills in some blanks:

This exhibition will offer the most thorough examination of both the historical and contemporary significance of factory-produced architectures to date. With increasing concern about issues such as sustainability and the swelling global population, prefabrication has again taken center stage as a prime solution to a host of pressing needs. The prefabricated structure has long served as a central precept in the history of modern architecture, and it continues to spur innovative manufacturing and imaginative design....

The exhibition will examine this phenomenon through historical documents, full-scale reassemblies, and films that trace the roots of prefabrication in the work of architects including Frank Lloyd Wright, Jean Prouvé, and Richard Rogers, corporations such as Lustron, and the imaginative systems of other influential figures, including Thomas Edison and R. Buckminster Fuller.

This contextual component of the exhibition will provide the foundation for a handful of full-scale commissions to be built in MoMA's vacant west lot....The fabrication and delivery of these projects will be documented in a special online exhibition, which will underline prefabrication's importance as a matter of process over product. Furthermore, the delivery and assembly of these projects will function as a real-time urban event that will be visible to the general public from the city streets

A Prefab Project says:

Perhaps notable for the absence of any of the commercially successful prefab architects working in the US, still kind of a big deal...
