The house was probably built by the then owner of the Farm, the Marquis of Three Rivers. It was remodelled by the Count de Prates and in this remodelling he included 10 bathrooms, magnified the house adding its extremities and making the attic inhabitable. Its concern was to offer comfort to the visitors of the Farm, which was considered a model. As these visits came by train using the old São Paulo Railway Company, they needed to sleep in the Farm to be able to come back to São Paulo the following day. The Farm was a pioneer in Brazil when it comes to producing electric energy and having piped water and bathrooms in the main house, the material was entirely imported from Europe; wall, floor and roof tiles, taps, light switches, candelabra, toilets, wash basins ; actually the hydraulical and electrical parts of the house. Everything continues to be the same because in 100 years, very little was modified. Notice the excellent finishing of the woodwork (gates, windows, ceilings and wooden floors) worthy of a city house as related by the guests. All the wood was cut and prepared at the Farm's sawmill equipped with German machines and being able to produce furniture with the same European standards.
