Atelier PHI-A has a specialist architecture division. The firm distinguishes itself by incorporating into both new construction work and the renovation of historic buildings the environmental values that lie at the heart of the Phi ethos.

From new construction to the renovation of historic buildings

Based in Nyon, Switzerland, the firm manages a diverse range of projects. Examples include the construction of buildings bearing the Minergie label, a marker of energy efficiency governing comfort, economy, performance, construction quality and environmental preservation. These values inform the day-to-day work of Atelier PHI-A and its entire team.
