Prefabrication experiments - 130 - settings - 1 - Operation Breakthrough - The Townland System

Under the direction of George Romney from 1969 to 1973 the department of Housing and Urban Development in the United States initiated a massive housing program to underwrite the progress of mass marketable and reproducible strategies for all income levels and particularly for low-income families. Along with reducing costs, Operation Breakthrough was to redefine building culture in the United-States and generate for the building industry what mass production had brought to every other economic sector: greater productivity. A phase I request for proposals drew 236 entries from which 22 test sites were chosen for prototype development. Of the 22 prototypes only nine test sites were eventually completed. The nine test sites included Indianapolis, IN; Kalamazoo, MI; King County, WA; Jersey City, NJ; Macon, GA; Memphis, TN; Sacramento, CA; Seattle, WA; and St. Louis, MO.

Further to innovation in building, the program also proposed a fertile ground for cross industrial/political collaboration. The program’s high expectations encouraged partnerships and vertically integrated housing schemes from marketing to land development and mass manufacturing. The cross-pollination was necessary to achieve housing production in the hundreds of thousands in a relatively short period of time. The lofty goals unrealized, the program is considered as another failure in bridging the gap between construction and factory production. Production never transcended the nine test sites, however the program did demonstrate some radical building systems.


The Townland, supported land system, was a notable example of 20th century megastructure principles applied to low cost housing. Initiated by Boeing and suggested by Building Systems Development, part of the ongoing research at Berkley, the 58 units were eventually built by a consortium headed by Keene Corporation. The supported land system stacked concrete slab streetscapes. Each of the stacked streets supported by a regular grid of columns was subdivided into private (infill), semi-private and public pedestrian areas (infrastructure). A lightweight construction system made up of steel channels was assembled on site to allow for potential unit customization and adaptability over time. The massive concrete infrastructure included provisions for exterior courtyards and landscaping on every level.  A novel form of vertical intense urbanism, the 58 units at the Yelsler Atlantic site in Seattle, appear as a small fragment of what the system intended.
