Fermat Villa originated from a sketch in which I tried to reproduce the lobby with the curved staircase that forms, together with the opening in the slab, a spiral design and is illuminated by an upper door facing a veranda. This vestibule belongs to another mansion here in Londrina that I really appreciate, which is José Garcia Molina's, dating from 1968. The arrangement of some rooms, aligned and facing the side street, is a characteristic of the Pedriali mansion that I used for the first time. When I drew the sketch, I conceived almost the entire ground floor and when I took it back and copied it, it acquired its current form. Fermat Villa remained a rough sketch, but was completed and copied with skill and ingenuity. The result is a beautiful, imposing and elegant mansion.
