The PROTO collection is an offering that supports Research & Development here at JOHI. This collection houses digital concept pieces, developed to 3D rendering. Each is a concept we are considering adding to our standardized, built collection. Until we get to that stage, we offer these designs to be built with a reduced starter price. So when you purchase a PROTO piece, it is with the understanding that your purchase will be the first public facing build of this design. All PROTO designs receive our 2-year residential warranty, just like our standard collection products.
