The Factory House began to be constructed in 1785 and was finished in 1790. The plan is ascribed to consul John Whitehead and is inspired by the neo-palladian English style.
The main façade presents a classical look and is composed of four registers. The ground floor is formed by seven arches that lead to an outside gallery and to the entrance of the building. The main floor is composed of high openings, with balconies and frontons. These are curved at the far sides and triangular at the middle portals. The second and fourth floors, conceived with the form of mezzanines, have parapet windows, therefore of small dimensions. The façade ends with a platband, decorated with balusters and festoons.
Inside, the famous staircase with the respective skylight, the ballroom and the monumental kitchen are worthy of mention. Located on the last floor, the kitchen still keeps all the original equipment and the primitive table ware.
