The historic premises in via della Chiusa are now nothing but a distant memory. The number of orders for motorcars is such that, some years before, the whole business was moved to via Montevideo, number 19.
The premises occupy the entire block and cover an area of 32,000m2, of which 20,000 are under cover and there are about 400 employees: it is the largest coachbuilding firm in Italy.
Here, each year, more than 100 motorcars take shape, components for the burgeoning automobile and aeronautical industries are produced and work is carried out for third parties. The galvanic chroming division, the first in Italy, in addition to chroming parts for the vehicles, also does work for outside companies in the fields of componentry, small metal parts and furnishings. Here too, all the finishes that combine to form the internal furnishing fitted in the Wagon-Lits company’s railway carriages are produced, even those for the legendary Orient Express.
In the afternoons, well-dressed people can regularly be seen walking through the divisions. They are the customers that, accompanied by the managers, are checking the lines of their vehicle, selected months earlier from pictures, are looking at materials and colour samples in order to make their final choice of finish.
It seems as if some of these have developed the habit of having an aperitif with friends at Castagna, so as to share the joys and difficulties of making their choices.

A renowned journalist of the time, struck by the level of creativity achieved by the system, defines this place as “the dream factory”.
