Frank Gehry`s Schnabel House, the Lawson-Westen House by Eric Owen Moss and the Drager House by the late Franklin D Israel are three key buildings in the development of a recognized style of Californian residential architecture. The houses perpetuate the Los Angeles tradition -- accomplished and exuberant, they are characterized by shifts in geometry, frequent use of utilitarian materials and subtle subdivisions. Complex enough to be confusing at first glance, these exhilarating designs blur the distinction between art and architecture and helped to establish their architects as masters of spatial manipulation.
