SEMPERVIRENS, which means always green in Latin or evergreen, is a technical design office specializing in landscape, town planning, environmental engineering and design. The agency's projects reveal and enhance the natural elements while preserving the ecosystem. Our projects magnify the wind, the sun, the water cycle to express our neo-romantic professions of faith “Man as servant and protector of nature” and “To serve nature out of love for humanity”. We want to review the relationship between humanity and its environment. Philosophy SEMPERVIRENS develops landscaping that is economical in resources, hypercontextual, using a majority of native plants. This botanical projectual desire releases atmospheres that are specific each time since they are specific to the site, adapted to geology, pedology, microclimate ... The aim of this approach is to preserve heritage biodiversity, to reconstitute degraded ecosystems as opposed to “standardized” plantations. On the contrary, the form of the installations can be very architectural, in dialogue with the building, in contrast with the natural ecosystem. Who are we ? The SEMPERVIRENS team of engineers brings together multiple skills in the field of ecological infrastructure, agriculture, the reconstitution of natural ecosystems, water management and development in classified heritage sites but also in the fight against water and air pollution and the realization of participatory developments. The agency was created under the leadership of Frédéric-Charles AILLET, in 2004, while he was still a student, he imagined the SEMPERVIRENS project to provide creative solutions to the ecological crisis of the Anthropocene. In 2005, his work as a landscaper at Nicolas Michelin (ANMA) was noticed. This is how he was selected to participate in the competition for the French Embassy in Tokyo, Japan, which he won. This garden will receive numerous distinctions: American Institute of Architects Prize 2012, Victoires du paysage 2014...
