On the exterior the pediment is decorated with a blank cartouche supported by acanthus with a swag under the clock. The curved pediments of the ground floor windows contrast panels of acanthus with blank cartouches draped to sunflowers with others framed at their centre by shells with lion heads and a variation with acanthus set against a curved background. One horizontal candelabra panel divides two of the windows. On the platforms, pairs of cast-iron columns with blue bases and capitals run the length of the platform with four decorative brackets supporting the canopies.
