Steel frame, 23 stories, 102.7 m (337 feet) high 
The black brickwork on the facade was chosen to lessen the visual contrast between the walls and the windows and thus give the tower an effect of solidity and massiveness. The Gothic-style pinnacles and the terra-cotta friezes on the edges of the setbacks are coated with gold. 
The base is clad in bronze plating and black granite. There are carved allegories, symbolizing the transformation of matter into energy, quite appropriate for a heater company. The entrance lobby is decorated with black marble and mirrors.
