Hôtel Saint-François, dit aussi Hôtel de la Perle
MonumentHidden Treasure
A little-known jewel of Bordeaux, the Hôtel Saint-François is astonishing for its daring construction: as early as 1854, Antoine Audubert used structural steel and suspended floors, a visionary precursor of modern industrial architecture.
History
Tucked away in the urban fabric of Bordeaux, the Hôtel Saint-François - also known as the Hôtel de la Perle - is one of the most unique architectural experiences the city has to offer enthusiasts of its industrial and technical heritage. Listed as a Historic Monument since 2013, this nineteenth-century tenement building is baffling in its apparent discretion, but fascinating once you understand its manufacturing secrets. What radically sets the building apart from its contemporaries is the systematic use of steel as the structural material at a time when stone and brick reigned supreme in French civil architecture. The floors do not rest on traditional load-bearing walls: they are suspended from powerful metal beams running across the top of the building, a structural principle that recalls the daring designs of the great engineers of the second nineteenth century, long before Gustave Eiffel made it his trademark. The experience of visiting the building is more of an investigation than simply cultural tourism. You have to look up, look for the details, understand how this building stands up according to a logic that is the opposite of that of ordinary construction. The facades, sober and bourgeois in appearance, conceal a structural revolution that only the discerning eye can detect at first glance. Located in Bordeaux, a city listed as a UNESCO World Heritage Site for its eighteenth- and nineteenth-century architecture, the Hôtel Saint-François is part of a dense, elegant urban environment. Its value lies not in decorative ostentation but in technical innovation, making it a particularly valuable monument for architectural historians, engineers and anyone interested in the genealogy of modern construction.
Architecture
The Hôtel Saint-François is in keeping with the formal vocabulary of Bordeaux's Second Empire commercial architecture: ashlar facades, regularly ordered bays, cornices crowning the whole in accordance with the Haussmannian canons that were triumphant throughout urban France at the time. At first glance, nothing betrays the building's structural singularity, which paradoxically contributes to its interest: the revolution is internal, invisible, underground. The central construction principle is based on a steel skeleton used as the main structure at a time when this material was still reserved for industrial buildings, market halls and large railway stations. Audubert transposed it to the apartment block with remarkable boldness. The main beams run along the top of the building and serve as anchors for metal hangers that support the floors of each storey: this is the principle of the cable or tension rod structure, which was to be found much later in some twentieth-century skyscrapers. This structural organisation offered considerable advantages in terms of the flexibility of interior spaces: freed from the constraints of intermediate load-bearing walls, the floors could be cut up and organised freely, anticipating the principles of the free plan that Le Corbusier would theorise almost a century later. The hygienic dimension is also evident in the generous ceiling heights and air circulation facilitated by the absence of heavy structural partitions.
