Immeuble, 13 allée de Turenne, 18th-century monument on Quai Turenne in Nantes, France

The Immeuble Perraudeau rises four storeys on the quai Turenne, its five-bay facade of tuffeau and granite topped by a triangular pediment with a round window and sculpted reliefs. Segmental-arched openings light the ground floor and entresol, including a light-blue door with a round window; tall windows with wrought-iron balconies mark the upper floors, and a shop sign reading "Bijouterie" hangs at the left.

The plot, lot no. 10 of the Feydeau island development, was bought in 1752 by architect François Perraudeau and sénéchal René Leroux from the heirs of Pierre Sarrebourse d'Audeville. They split it in two and built adjoining rental buildings around a shared courtyard, entered at 21 rue Kervégan. The facades and roof were listed as a monument historique on 5 December 1984.

The building reflects the merchant culture of Nantes during its commercial peak, with design elements that accommodated wealthy traders and business families. Its decorated facade and refined details show how successful merchants displayed their status through architecture.

The building stands on the west side of Île Feydeau, along the quai Turenne; its shared courtyard entrance is at 21 rue Kervégan. The facade is best seen from the quay, where the pediment, the round-arched ground floor and the wrought-iron balconies are visible from the public street. The shop sign reading "Bijouterie" marks the left edge of the facade.

The facade still shows the corrections made after the building began to shift as the walls rose, a consequence of the oak-pile and raft foundations. The triangular pediment, typical of the construction period, carries a round window and sculpted reliefs above the central bay.
