Prefabrication experiments - 162 - Building Kits - 03 - Modular Housing System



Scaffolding and industrial racking systems employ agile, flexible, reversible and sometimes universal connectors toward modular and infinitely variable arrangements. Industrial systems from the steel Uni-strut to Bosch aluminum framing assembled in a myriad of options inspire and speak to the ideal of a type of do-it-yourself architectural kit geared toward an inclusive and integrated customizable building strategy. Relatively recent experiments by Kieran and Timberlake (cellophane house) and the canonical example of Charles Eames’ Case Study House no. 8 elucidate how off-the-shelf components could be utilized in mainstream construction. The ready-made architectural pieces highlight a conceptual ideal of a no cuts, no waste, no nails, no frills, and a no special tools approach to productive construction.


Kithaus, a 2005 experiment designed by company co-founders Tom Sandonato and Martin Wehmann makes use of linear aluminum members and dimensional standardization to systematize an infinitely variable grid based on compatible parts. The company proposes a box-framed micro dwelling assembled from the patented Modular Housing System. The interlocking post, beam and panel system was conceived as a critique of conventional and high waste timber stick framing. MHS proposes a design “tool box” based on a 4-foot grid used to coordinate floor, wall and roof structural insulated panels which can be assembled and disassembled to and from the aluminum post and beam extrusions. Each structural element is extruded with a male-female tongue and groove section. All linear members are prefabricated to the correct dimensions. The square profile comes in several options with differing extruded profiles on each face (corners, mid-span posts, end-posts). A type of curtain wall frame, the infill panels could be made from any material. A concealed bolted connector allows the grid system to be deployed in x,y and z axes. The patented masterlock connector uses a bolted clamp that grips onto the tongues of the extrusions to create a tight-fitting friction joint. The infill strategy although not be ideal for energy efficiency as the system does not eliminate thermal bridging, the aluminum structure could be adjusted to apply insulated panels on the outside of the structure. The easily dry-assembled kit architecture aspires to eliminate construction complexities and become totally reversible and reusable.
