The Edouard de Biolley Hotel, built in the second half of the 18th century in the Louis XV style, bears the name of its patron. It is made of brick and also uses Meuse limestone. The front façade has three levels and seven bays. The building was extended in 1860 in the Empire style, which was very fashionable at the time. This extension consisted of the addition of a grandstand, made of stone, used by the Biolley family for parties, parades and processions. A balcony, a third floor and the right-hand portal were also added.At the rear, the building has three levels and five bays. A porch with six columns was added later.Edouard de Biolley, Raymond's younger brother, lived in this building. Raymond lived a few steps away from his brother, on Place Sommeleville. Together they ran the family business, whose buildings extended behind the houses. The Biolley family, originally from Haute-Savoie, played an important role in Verviers. Businessmen (but also women), powerful and wealthy, some played an important role in municipal and even national politics.
