The style for a birdcage elevator dates back to the turn of the 20th century. Many buildings at this time were designed with ornate metal elevators, referred to as birdcage elevators, which were operated manually. Birdcage elevators at the time were designed as square or rounded cars, but the actual “birdcage" feature came from being able to look out of the elevator car at the surroundings. Vintage birdcage designs for an elevator mobility system aren't obsolete, however, as many consumers look for an antique elevator to match the look at the feel of their home or business.
