We are a multidisciplinary team of committed development experts.

As outdoor architects, landscape planners and pathway designers, we combine our skills in the service of the transition of territories and public spaces.

Madeleine Masse
Founder, urban planning architect

Madeleine is an ADE HMNOP urban planning architect, with degrees from ENSA Paris-Belleville and the Technische Universität in Berlin.

She has been committed to resilient, bioclimatic and environmentally militant urban planning for 15 years, and began her career at APUR - Atelier parisien d'urbanisme, where she helped to define the planning principles for Paris's green belt, seeking to reconcile use, accessibility and biodiversity.

For 8 years, as head of a department employing around forty people at a major Parisian agency, she carried out urban planning projects in the vicinity of major mobility hubs (stations, interchange hubs, intermodality, stations, etc.): accessibility and mobility are central to her practice. She advocates inclusive urban planning, and develops a project design method to adapt the city to children.

She has also worked on a number of territorial strategy projects: in 2020, she is taking part in the "Luxembourg in transition" project to decarbonise the functional region of Luxembourg, launched by the Luxembourg Ministry of Energy.

In 2022, to pursue her commitment, she founded ATELIER SOIL, whose mission is to support players in the adaptation and decarbonisation of territories at all levels.

She sees innovation, forward looking, and a multi-disciplinary approach as project tools to meet the challenges faced by local territories regarding climate, health, social and societal risks. She advocates a sensible approach to urban development that produces resources.

Capucine is a space designer, a graduate of ENSAAMA Olivier de Serres, and an architect, a graduate of ENSA Paris-Belleville. She obtained her HMONP in 2022, and since then is working on how to reconcile the entrepreneurial constraints of an agency with architectural ethics.

In addition to her architectural practice, Capucine has always explored various creative media (photography, writing and illustration). Within the agency, she designs projects for public spaces and maps of the Anthropocene.
