Plug-On is the first in a series of product prototypes intended for residential structures. It was fabricated and assembled in Houston, then delivered and installed onto an existing modest one-story ranch style house in Richardson, Texas. The client was interested in an addition that would complement the existing language of the house and accommodate a sitting area to redirect the space of the master bedroom to the lush trees in the rear lawn. Our directive was to maximize the qualitative effect of the square footage. Plug-on is an eight-foot cube, fabricated entirely of stainless steel, glass and wood. It is structured as a cantilever using a concrete counterweight and steel beam fulcrum underneath the bedroom floor.
