François COSTE
Architect & urban planner · Founder of COSTE Architectures
(1937 - 2019)
Architect & urban planner Founder of COSTE Architectures
There are trajectories that leave a lasting imprint, not through the noise they make, but through the accuracy they install over time.
François Coste belongs to that generation of architects for whom the project was never an isolated object, but an attentive response to the territory, the city and the human relationships it shelters.
Born in Aix-en-Provence in 1937, François Coste trained in architecture and engineering in Lyon (INSA), then in Marseille at the École Nationale Supérieure des Beaux-Arts. This dual education would mark his practice durably, at the crossroads of technical rigour and architectural sensitivity, nourishing a complete vision of the project — from structure to use.
He began his career within recognised practices in the Provence–Alpes–Côte d'Azur region, notably at SETAP in Aix-en-Provence and Faure-Ladreyt in Marseille. These early experiences anchored him in large-scale projects and reinforced his interest in urban issues, the composition of ensembles and the coherence of built fabrics.

These early experiences anchored him in large-scale projects and reinforced his interest in urban issues, the composition of ensembles and the coherence of built fabrics.
« Architecture takes on meaning when it orders the city, respects the territory and creates a lasting human relationship. »
He then devoted a full year to urban planning as study director at the GEP Urban Planning Studio of Hérault, deepening his reflection on the city, its dynamics and its evolutions. After several years as head of agency at the Atelier Lopez, he chose to set up his own practice.
In the 1980s, in Montpellier, François Coste founded what would become COSTE Architectures. There he laid the foundations of an independent studio — demanding and attentive to the challenges of the territory — based on curiosity, transmission and the quality of dialogue between project stakeholders. This decision marked the starting point of a structuring professional adventure, destined to evolve and transform over the decades.
Throughout his career, his major preoccupation remained urban order and landscape. He developed a constant reflection on how architecture inscribes itself in the city, structures lived spaces and dialogues with the existing context. This approach translated into many studies, competitions and built projects on neighbourhoods, new towns and operations to restructure urban fabrics.
Visionary and rigorous, he also opened the agency very early to innovative approaches, particularly in the field of public facilities and industrialised constructive systems, thus laying the first foundations of what would later become a strong speciality of the agency.

Alongside these large-scale projects, François Coste maintained a deep attachment to domestic architecture. The single-family house, when it engages in a close dialogue with the client and the site, represented for him a privileged space of architectural and human expression. There he found a direct, personal — sometimes intimate — relationship that demanded great availability and constant commitment from the architect, a conception of the profession deeply rooted in listening and relation.
François Coste passed away on 24 December 2019.
His legacy is not fixed in any single form or era. It lives on in a way of thinking architecture: attentive to context, respectful of territory, demanding in its relationship to the project and deeply rooted in human relations.
This legacy continues to inspire the agency's approach, in an embraced continuity of transmission, evolution and commitment.
COSTE Architectures pays tribute to him with gratitude.
For what he transmitted, for the foundations he laid, for his moral uprightness, and for that constant search for accuracy that continues to inspire the agency today.
