Prefabrication experiments - 70 - S.I.R.H. Modular housing system by Jean and Claude Prouvé

The twentieth century introduced a plethora of new services to buildings in order to enhance comfort. From electrical services to plumbing and air conditioning, simple pre-industrial building culture evolved into a complex entanglement of systems and services. Management of this entanglement became a dominant theme of building technology. Modern methods of construction are for the most part concerned with setting clear, synthetic, efficient and interchangeable paths for each building system. Evolving from an elucidation of systems, «open building» theory was articulated to the sorting out of building systems and facilitating their flexibility over time.

This type of «open» and «evolving» approach to building was characteristic of prefabrication strategies during the latter decades of the twentieth century. The avant-garde experiments of the early twentieth century and the early failures of the factory mass-produced dwelling gave way to a new generation of architects arguing for mass produced flexible and adaptable component systems that would respond to the variable needs of the modern dweller.

The well-known French designer and architect Jean Prouvé was recognized for his research into industrial processes and notably for his exploration of the curtain wall. His legacy is well documented in architectural history. His dream of an industrialized architecture was also carried by his son Claude Prouvé and was expanded through the invention in 1973 of a modular monocoque component system. The father and son collaboration on the  «Société industrielle de recherche et de réalisation de l’habitat» industrial research for housing project was based on the clustering of geometrically compatible structural foam injected shells for floors, walls and columns.


The post and panel component system could evolve over time, be repurposed, replaced and even disassembled once no longer needed. The main differentiating point between this open system and the plethora of component systems designed during this period was its vertical mechanical shaft used to distribute mechanical and electrical services. The shaft was used as a core element around which the dwelling’s services, bath and kitchen, were articulated leaving the remainder of the composition open to a modular assembly of 3.8, 5.3, 7.6m sided volumes with a height of 2.5m. Only one of these prototypes was completed.  These meta-industrialized systems failed to take root, as housing, collective and single dwellings, continued to be produced independently.
