Martin started in 1880 his first factory at the address 90 Boulevard de Ménilmontant, a L-shaped 6-storey building ( ground floor, 4 floors, attic floor) and a backyard, in the middle of the building is an porch that leads to the backyard, this building was built around 1860
As a starting manufacturer, he must have rented only a small part of the address 90 Boulevard de Ménilmontant.
Due his commercial succes of the “Petit Garçon Livreur” (the delivery boy) in 1888, (we know this toy as the “Le Livreur”) Martin has now the money to acquire a new building to expand his factory.
In 1892 he acquired the adjacent building number 88 with a square form and after a renovation / rebuilding around 1900, the factory was a lot bigger than his old factory and was, for that time, a revolutionary conception.
After Bonnet’s departure, the facade of the building 88 Boulevard de Ménilmontant was adjusted, the old facade was a pointed facade and the new facade suggested a flat roof, but behind this facade there is still a pointed roof.
