The Heating plant and main controls cabin is a technical facilities building in Firenze Santa Maria Novella railway station designed by architect Angiolo Mazzoni in 1929.

The project was approved on 9 February 1932 by decree by Costanzo Ciano, minister of postal and telegraph services, as a correlated work for the new station with an 11,500,000 £ budget.

The contract for the iron works, the four boilerplates with vertical water tubes and three drums, their "Prat" type chimneys, the catwalk above them and the helix stairs was awarded to Anonima Pignone in February 1934.

The formal connotation, with references and quotations borrowed from the Futurist and Constructivist experiences, relies substantially on the open and immediate declaration of the technological functions taking place inside.

Giacomo Devoto claimed the main controls cabin and its 280 levers to manage railswitches and signals as the most perfect, most complex and complete, the most beautiful thing that exists in Italy and maybe in the World.
