Dating from the 18th century, it was renovated in Art Nouveau style in the early 1900s at the request of Léon Losseau by Paul Saintenoy.

The entrance door is detached, consisting of black cast iron columns decorated with golden leaves (1908) and fuchsia flowers of the same color.

A canopy with wooden beams overlooks the living room, which was decorated in 1911 by 15 pâte de verres of Amalric Walter representing the Belfry of Thuin and the river Sambre.

It was completely renovated by Paul Saintenoy who was contacted in 1899 by Léon Losseau, lawyer, bibliophile, photographer and art patron.
