Frédéric-Charles AILLET

Founder of Sempervirens - Landscape architect-urban planner

Born from a long family tradition encompassing of thepaintersWorking with engineers and architects, he developed original neo-romantic park and garden designs, his projects magnifying the power of nature and contrasting natural elements with humanity. His passion for garden design and his desire to create the SEMPERVIRENS design office, which means "always green" in Latin, stemmed from a desire to protect the environment.

In 2006, upon graduating, his talent was noticed while he was working for the architect Nicolas Michelin, and he was subsequently invited to participate as a landscape architect in the competition for the French Embassy in TokyoArchitect Tadao Ando, who chaired the competition jury, declared the winning team thanks to the quality of the landscape design, which launched his career. He recently won on a 13-hectare site. the Campus of the new French University of Egypt in Cairo with the architects Jakob Macfarlane and the Cognac 4 Elements Park with Jean-Michel Wilmotte.

Over the course of the projects across the worldFrédéric-Charles AILLET has developed an expertise in ecosystems adapted to extreme conditions. His studies of marine, mountain, and desert ecosystems allow him to propose technical innovations applied to green architecture, water recycling and phytoremediation, and the creation of dry, xerophytic gardens. He adopts a biomimetic approach, integrating ecosystem services into projects, for example, to reduce air pollution.

His gardens evoke the beauty of the struggle for life and the poetry of natural elements: the wind, the course of the sun, the water cycle staged according to the project sites.
