His son Antonio expanded the premises to cover the entire block. In 1826 Antonio Pedrocchi presents to the municipal authorities a project for the construction of a plant, including premises used for roasting coffee, and ice-making. He also asked Giuseppe Jappelli, engineer and architect already to redesign the premises. Jappelli had to integrate different buildings and facades into a single unit, creating an eclectic exterior of diverse facade. The interior has neoclassical elements. The coffee house from the early years became known as "coffee without doors" because until 1916 it was open day and night. This dictated an independent structure with an open porch and no windows, making a "transition" into or from the city.
