We are Atiaîa.

We contribute to the success of the built environment and to the well-being of its users through lighting design projects, consulting and research.

About us

The perception of the relationship between light and materials is the basis of architectural visual experience, which allows the understanding of the elements that form an environment. Lighting design can contribute to creating meaning and impressions in those who experience a space. Our aim is to contribute to the success of the built environment and to people’s well-being through research, consulting and lighting design projects.
