Nested on the edge of the river Seine in Paris, these housing units are now possible thanks to « la Loi Alur », a new legislation that allows urban heightening.

They do not require any lot acquisition as the rights to buil is obtained in exchange for a common partsof the existing building’s renovation.

Thus, we are able to propose green housing 40% below the real estate market price, built without any nuisance in workshops, in an extremely short time thanks to our patented panels and unique technique of prefabrication. These patents were achieved in collaboration with a team of engineers and specialists from “Les Toits du Monde”

These energy plus houses are modular systems that can be extended depending on the user’s needs.

Building on top of roofs is not only an ecological and economical solution, it’s working against the urban sprawl that kills the social link. It’s also a contemporary way to discover new perspectives of the city, a new Paris above the horizon.
