The construction system developed by Bibiano Duclos and patented in 1890 consists of a metal framework of vertical load-bearing columns spaced one meter apart and connected by prefabricated sheet steel infill panels forming the outer skin of the double-walled house. The roof is covered with corrugated iron.

This modular and removable system allows great flexibility in the size and layout of houses according to the desired program. It highlights the desire of the time to build light, portable and affordable houses thanks to the prefabrication of parts and the ease of assembly of the structure without requiring skilled labor.

The Duclos workshops were located in Courbevoie and they were active from 1890 to 1900. The production of the Duclos houses thus lasts only about ten years, but a major advertising campaign offers to the project its notoriety.

Although prefabricated in the factory, the constructive elements of the house are not devoid of ornaments. The panels have a variety of shapes and decorations depending on their location on the structure: they have a square shape in the lower part, rectangular on the side walls in the upper part, triangular or trapezoidal on the gables. The molded sheet metal plates have grooved or diamond-point patterns. To these structural elements are added openwork friezes above the openings, lambrequins along the edges of the roof, metal shutters decorated with stylized flowers…

The terrace is covered by a protrusion of the roof resting on thin metal ties, which contributes to the elegance of the dwelling.
