Expertise – Natural Hazards, Climate Adaptation and Resilient Architecture

​

Understanding and Integrating Risk from the Earliest Design Stages

For every architectural project undertaken in Carnac and throughout the Morbihan region, the analysis of natural hazards and local climatic conditions forms an essential part of the design process.

Flooding, coastal inundation, stormwater runoff, prevailing winds, coastal erosion and increasingly frequent heatwaves all directly influence architectural decisions.

Our objective is not simply to comply with planning regulations, but to anticipate the long-term impacts of climate on buildings in order to enhance their durability, resilience and user comfort.

​

Flood Risk and Hydraulic Constraints

Projects located in flood-prone areas or coastal environments require a specific design methodology that takes into account both the characteristics of the site and the applicable planning regulations, including Flood Risk Prevention Plans (PPRI) and hydraulic studies.

Our expertise enables us to:

• adapt building layouts to the natural topography;

• determine appropriate finished floor levels and access strategies;

• anticipate water flow paths and areas of potential ponding;

• design resilient and adaptable spaces;

• reduce the impact of extreme weather events.

Each project is developed with the objective of reducing the building's vulnerability while preserving architectural quality and functionality.

 

Summer Comfort and Heatwave Adaptation

As the climate evolves, ensuring summer thermal comfort has become a key design challenge, even within temperate oceanic climates.

Increasingly frequent periods of extreme heat require passive design strategies to be considered from the earliest design stages.

Our architectural approach integrates:

• building orientation and solar exposure;

• passive solar control;

• natural cross-ventilation;

• thermal mass and material performance;

• façade and glazing protection.

The aim is to deliver naturally comfortable buildings while reducing dependence on mechanical cooling systems.

​

Coastal Conditions, Wind and Climate Exposure

Within coastal environments, particularly around the Gulf of Morbihan, prevailing winds and marine conditions play a significant role in shaping architectural design.

Comprehensive site analysis allows us to optimise:

• building orientation and site integration;

• protection of outdoor living spaces;

• the durability of materials in marine environments;

• thermal and acoustic comfort.

 

Collaboration with Specialist Engineering Consultants

To ensure the technical robustness of every project, we work closely with a network of specialist engineering consultants, including:

• structural engineers;

• mechanical, electrical and thermal engineering consultants;

• environmental and hydraulic engineers;

• geotechnical engineers, where required.

This multidisciplinary collaboration enables technical expertise to be integrated into the architectural design process from the earliest stages.

 

Environmental Certifications and Sustainable Design

Where appropriate, projects may incorporate recognised environmental assessment methods and sustainability certifications.

Our approach includes:

• improving thermal performance and summer comfort;

• specifying bio-based and sustainable materials;

• optimising building energy performance;

• addressing embodied carbon and environmental impact;

• supporting certification processes where relevant.

These strategies contribute to a coherent relationship between architecture, environmental performance and long-term building resilience.

 

Architecture Designed for Contemporary Challenges

This integrated design approach enables us to create buildings that are:

• carefully adapted to their specific site;

• resilient to climate-related hazards;

• comfortable throughout the year;

• environmentally responsible and resource-efficient;

• designed to meet the challenges of a changing climate while delivering lasting architectural quality.
