The Greek scholar Heron of Alexandria created the earliest known automatic door in the 1st century AD during the era of Roman Egypt. The first foot-sensor-activated automatic door was made in China during the reign of Emperor Yang of Sui (r. 604â618), who had one installed for his royal library.
Reminiscing back to a time in America when things were built well and built to last, our handcrafted sliding barn doors make a purposeful statement in any space. Our doors are made from select species of woods that have beautiful natural characteristics and a feeling of quality to the touch. Our barn doors add a unique statement to any design style. Their seamless, non-obtrusive functionality makes good sense. In short, we refer to sliding barn doors as âFunctional Artâ. We build each and every barn door and barn door hardware system as if it were being installed in our own home. We would welcome the opportunity to build a barn door for you.
