The purpose of creating the archives of The Sekisui Heim M1


The Sekisui Heim M1, was the sole selection among houses which had been produced by the industrialized construction method for the gSelection of DOCOMOMO 100 Japan.h We developed it together with Dr. Katsuhiko Ohno, pursuing high performance and high quality in the stages of its development, by adopting the innovative technology of the Unit Construction System. It was introduced at the first gTokyo International Good Living Showh in 1970.  Ever since that time, we have been supplying these units for housing additions and for renovation requirements to the approximately 10,000 homeowners who still live in those houses.

We are pleased that the Sekisui Heim M1 has been recognized as a cultural asset, to be preserved as a piece of architectural history. In consideration of its social importance, and of the purpose of DOCOMOMO, we have initiated research on our own Sekisui Heim M1 and we have taken measures to preserve the documentation on it.  In 2004, we moved one of our original Sekisui Heim M1 houses for the purpose of preserving it. We then proceeded with the making of archives of collected materials, part of which is available for viewing on our web site. It will be our pleasure if this site is useful for further understanding of the Sekisui Heim M1 and can help in the study of the modern movement of architecture.

In 1960, during the postwar economic growth, cities began to develop rapidly. This boom, however, did not improve the living environment, but created chaos instead. In addition, a high demand for housing caused hikes in housing prices and shortages of materials and craftsmen. This was considered to be a severe social problem. These circumstances led to the development of our Unit Construction System, the Sekisui Heim M1, for the purpose of accumulating good-quality living environmental stock by the renovation of the housing supply system. We applied industrialized technologies, which had begun to show promise in the housing industry at that time.

I expect that this web site, where all of the activities of the design, construction and supply of the Sekisui Heim M1 are covered, will be helpful for further research of the living environment and for producing fruitful results.
