Situated in the very centre of Vannes, these apartments enjoy a highly sought-after setting just moments from the historic walled town, with its vibrant mix of shops, restaurants and independent boutiques.

A pleasant ten-minute walk leads to the harbour, the starting point for numerous waterside strolls and excursions. From there, daily ferry services provide easy access to the islands of the Gulf of Morbihan.

The development is exceptionally well connected to the rest of the city, with a cycle path and bus services directly outside the building. Vannes railway station is just a ten-minute walk away and offers direct connections to Paris in approximately 2 hours and 30 minutes. Rennes and Nantes can both be reached in around one hour by car via the dual carriageway.

Named Le Sémaphore, this exceptional redevelopment breathes new life into Vannes’ former Administrative Complex, originally constructed in 1967. Completion of the project is scheduled for the end of 2028.

Characteristic of its era, the building’s original architecture is defined by a functionalist aesthetic, articulated through orthogonal lines and a regular façade grid. Today, this emblematic landmark of Vannes is being reimagined for a new generation.

In keeping with the projects that have earned the practice international acclaim, Lacaton & Vassal have approached the site by identifying and amplifying its inherent qualities, transforming its existing potential into an entirely new living environment. The development extends across four wings and six storeys, combining social diversity with a mix of uses including offices, workspaces, retail units, student accommodation and homes of varying typologies, from studios to villas.

Every aspect of the transformation stems from a rigorous analysis of the existing structure—a monolithic office building set within a relatively dense urban fabric—and a determination to unlock its possibilities. Winter gardens, expansive glazed surfaces and extensive landscaping have been introduced to strengthen the building’s relationship with its surroundings, while circulation routes have been entirely reconfigured to accommodate a diversity of uses and patterns of occupation.

This close reading of the site’s existing qualities becomes a catalyst for innovation. The completed project will also honour the building’s history through the preservation of key architectural elements, including the concrete structure, the original entrance hall, stairwells and lifts, as well as portions of the existing tiled circulation spaces.

Le Sémaphore exemplifies an architecture that is at once functional, restrained and generous. Through ecological responsibility and an economy of means, it will offer residents an exceptional living environment and a rich, expanded experience of both private and shared spaces.

This approach—simultaneously modest and luminous, and emblematic of Lacaton & Vassal’s work—embodies a forward-looking vision of architecture. It is a project destined to leave a lasting mark on the history of Vannes.

The transformation of Le Sémaphore is led by Lacaton & Vassal Architectes in collaboration with associate architect Emmanuelle Delage.

Graduates of the Bordeaux School of Architecture in 1980, Anne Lacaton and Jean-Philippe Vassal founded their practice in Bordeaux in 1987. Their early projects served as laboratories for a radical architectural approach grounded in ethics, resourcefulness and an economy of means. A seminal work in their career, Maison Latapie was awarded the “Remarkable Contemporary Architecture” designation in 2023. Over the years, they have delivered a series of landmark projects, including the Palais de Tokyo in Paris, the Nantes School of Architecture, the FRAC Nord–Pas-de-Calais in Dunkirk, and the celebrated transformation of Tour Bois-le-Prêtre in Paris, undertaken in collaboration with Frédéric Druot and Christophe Hutin.

Lacaton & Vassal have received numerous distinctions, including the Grand Prix National d’Architecture in 2008, the Équerre d’Argent in 2011 for the Tour Bois-le-Prêtre project, the Global Award for Sustainable Architecture in 2018, the European Union Prize for Contemporary Architecture – Mies van der Rohe Award in 2019, and the prestigious Pritzker Architecture Prize in 2021. These accolades have established the practice as one of the most influential voices in contemporary architecture worldwide.

Emmanuelle Delage graduated from the Bordeaux School of Architecture (ENSAP) in 1999. From 1996 to 2017, she worked within the Lacaton & Vassal practice, becoming a project director in 2001. During this period, she contributed to several major schemes, including the development of 96 social housing units in Chalon-sur-Saône and the Grand Sud multi-purpose cultural venue in Lille. In 2018, she established her own practice, pursuing a distinctive architectural vision through a range of significant projects. Her work includes serving as project director for NP2F on the Adidas Arena at Porte de la Chapelle, developed for the Paris 2024 Olympic and Paralympic Games, as well as overseeing the transformation of Les Bains-Douches Contemporary Art Centre in Alençon.

Since 2023, her collaboration with Lacaton & Vassal has continued through the conversion of Vannes’ former Administrative Complex into a new residential development, Le Sémaphore.
