A panoramic apartment in Les Horizons, Rennes’ tallest towers

The iconic twin towers of Rennes were designed by architect Georges Maillols in 1970. They represent the first high-rise residential building in France and have been labeled “Remarkable Contemporary Architecture” since 2000.

The Horizons I and II towers are among Georges Maillols’ most iconic works, profoundly shaping Rennes’ urban landscape in the 20th century. For these towers, he drew inspiration from Chicago’s Marina City towers (Bertrand Goldberg, 1964) and their corn-cob-like composition.

As France’s first high-rise residential building, the twin 30-story structures, standing at 99,5 meters tall, utilized revolutionary construction techniques for the time. Extensive industrialization and prefabrication allowed rapid construction, completing one floor per week. The buildings rest on a network of Franki piles, a pioneering method patented in the early 20th century by the architect’s uncle, Edgard Frankignoul, driven 10 meters deep into the ground. At the core of the structure, an elliptical reinforced concrete shaft houses vertical circulation. The apartment modules radiate around this central core, while the façade is clad in identical panels molded from a mix of white cement and crushed quartz, which catches the light.

Pop spirit and biomorphism in Rennes’ skyline

Aesthetically, these two towers are equally remarkable. Drawing from nature-inspired vocabulary, whether plant, animal, or human, the façade forms give Les Horizons a biomorphic appearance. They break away from the Modernist Movement and historical models. The use of curves and lines inspired by shells, skeletons, or honeycombs aligns with Pop Architecture, which was more widespread in the United States.

Georges Maillols

Born in 1913 and passing away in 1998, Georges Maillols is renowned for his influence on Rennes’ architectural landscape. A graduate of the École Nationale Supérieure des Beaux-Arts de Paris, he settled in Rennes in 1947 and contributed to numerous social projects, from urban renovations to emergency housing construction, in a city deeply scarred by World War II.

Influenced by architects such as Le Corbusier, Frank Lloyd Wright, and Oscar Niemeyer, as well as the geometry of the Bauhaus, Maillols emerged as a pioneering architect of the Trente Glorieuses (post-war economic boom). He transformed Rennes into his architectural laboratory, reinventing the typology of residential towers. He designed over 10,000 housing units, some of which became true icons of the era, such as the Horizon Towers and the Saint-Just Block.

Maillols did not limit his work to large urban complexes. Between 1973 and 1979, he designed several housing developments in rural communities and the outskirts of Rennes, where he conceptualized the “elastic house”, a dwelling intended to be adaptable and forward-thinking in response to urban density.

« We must construct the writing of our time with the techniques of our time. »

Maillols’ work is rooted in a quest for innovation and the use of contemporary techniques, making Rennes, even in its historic city center, a showcase of modernity. His extensive use of “architectonic” concrete enabled the construction of towering buildings, heavily inspired by his travels to the United States. His designs featured futuristic silhouettes marked by the graphic vocabulary of the façades.
