Rapport Annuel 2025 : de l’impulsion à l’usage

In the face of environmental, economic, and social transformations, architecture carries tangible responsibilities: designing spaces that endure, accommodate diverse uses, and integrate into sometimes complex economic and territorial balances.

In 2025, Patriarche continued to pursue this ambition within a shifting context. While international growth reflects strong momentum, it is above all the projects delivered this year that reveal its meaning: initiatives where sustainability, health, social value, and economic performance come together to create places that are useful, adaptable, and rooted in their territory.

From rehabilitated industrial campuses to scientific environments, from facilities to hybrid workplaces, a constant emerges: projects increasingly seek to reconcile a multiplicity of challenges, environmental, social, economic, and more.

In this context, 2025 has been a year of clarification. The firm has redefined its direction without renouncing its commitments, prioritizing thoughtful and realistic objectives capable of sustaining long-term growth. This trajectory is built on a collective in which every discipline, every entity, and every individual contributes to the overall dynamic.

This approach is structured around seven pillars, forming a continuum from project inception through to real-world use.

Driving momentum: anticipating needs, engaging territories

Even before drawing begins, understanding is essential. Driving momentum means capturing the dynamics of a territory, shaping a vision, and creating the conditions for a project’s feasibility.

In 2025, this capability is notably illustrated by SULLY Santenov in Dijon, where a healthcare ecosystem is emerging from close collaboration between public and private stakeholders. The project demonstrates that a building is not merely a programmatic response, but the outcome of a shared intentio

Designing: orchestrating complexity

Designing today means aligning uses, environment, and design within an increasingly demanding framework.
The year 2025 confirms the relevance of a multidisciplinary approach capable of addressing multiple challenges. In projects such as the transformation of the Montréal Biosphere or the Sartorius campus in Aubagne, this approach brings together technical performance, quality of use, and environmental ambition.

Building: giving form to intentions

Construction is a fully-fledged architectural act: it is the moment when the project truly takes shape.
Whether through the restoration of Notre-Dame de Paris or the construction of the new Nantes University Hospital, 2025 is marked by projects under construction management in demanding technical, heritage, and logistical contexts.

It also reflects the ability to ensure faithful, sustainable, and lived-in architecture, through entities such as Autumn and Myah, acting as general contractors. On projects like CentraleSupelec or Kadans, as well as on numerous developments in constrained or highly technical environments, building becomes a collective and exacting act, where precision, coordination, and commitment determine the final quality.

Developing: across all scales and all typologies

To develop means embracing a global vision while maintaining a local approach, embedding within territories and understanding their specific characteristics.

In 2025, Patriarche continues its international expansion with new offices, notably in La Réunion and Abu Dhabi, alongside the strengthening of its presence in Africa and North America. This momentum is built on a contextualized approach, enriched by collaborations and partnerships.

It enables the firm to address transforming sectors (healthcare, technology, industry, higher education) and to support these evolutions with grounded, site-specific responses tailored to each location.

Transforming: decarbonizing, regenerating, sustaining

Transforming means acting both on our business practices and on the projects we design.

In 2025, this responsibility is embedded within a structured CSR approach: reducing carbon footprint, evolving mobility practices, increasing the use of renewable energy, and monitoring impacts over time. This framework helps guide decisions in a concrete way and supports a sustainable trajectory.

It also extends directly into projects. At a large scale, the transformation plan for the Airbus site in Marignane reflects the ability to support a complex industrial site over time, integrating energy, mobility, biodiversity, and uses. At the building scale, projects such as the Nanterre Judicial Court illustrate another form of transformation: extending existing structures, improving their performance, and adapting them to current challenges.

Inhabiting: bringing places to life over time

A building finds its full meaning in the uses and life it accommodates, a conviction embodied through our entity Walter, operator, activator, and service provider.

The year 2025 marks a milestone in this focus on operations and user experience. The launch of the Walter Science offering and the opening of its first site in Basel illustrate this ambition to provide flexible, ready-to-use environments tailored to the specific needs of research and innovation.

Sharing: leveraging collective intelligence

Behind every project lies a human ecosystem: clients, partners, and teams.

In 2025, this dimension has been strengthened through a more cross-functional organization, collaborative ways of working, and a culture of continuous learning. This collective intelligence is now essential to addressing the complexity of projects and delivering responses that are technically sound, economically viable, and human-centered. This dynamic also relies on relationships of trust with our clients and partners, whose expertise and visions directly contribute to the quality, relevance, and feasibility of the projects.

A confirmed trajectory, open perspectives

Beyond growth indicators, 2025 above all confirms the strength of an approach.

An approach that views architecture as a holistic process, capable of connecting development, design, construction, and operation. In an uncertain context, this positioning makes it possible to address complex projects that crystallize multiple challenges.

It opens clear prospects for the years ahead: continuing to innovate, strengthening commitments, and designing places that respond concretely to the transformations of the contemporary world.
