Abstract: Loq·kit is a mass-produced system of interchangeable building components for assembling single or multi-family houses. The building components are of three varieties: structural frame, in-fill, or snap-cladding components. Except for bolted structural frame connections, all connections between parts are snap-lock, and may be released. With snap-lock interfaces and a modular dimensional relationship between components, they can be reconfigured in near endless variety. The components all share a common dimensionality that is derived from a regulating grid. The grid utilizes an alternating sequence of two modules—a module A, and a smaller module B. The A,B,A,B rhythm of gridlines is used to regulate component connection locations in three dimensions. The alternating-sequence grid works by establishing a standard connection width, module B, for making connections between components. Each possible connection width is spaced from another by a common module A.
