The Off Door Handle is easily one of the best door knob redesigns of all time. 'Off' is designed to make it easier to turn off the lights and gas in your house when you step out for an extended period of time.
The Off Door Handle was designed by Eun Ah Kim, Jinhyuk Rho and Maria Rho and won a 2011 Red Dot Design award. The handle would be hooked up to your home's gas and electrical systems. With a flick of the knob, you could instantly turn off your gas, electricity or both. 'Off' is beneficial to both the homeowner and the world as it takes homes off the grid when they are unoccupied. The less energy being wasted, the greener the Earth becomes!
