Osa Architecture

Agence OS-A is an architectural practice based in Saint-Tropez, founded in 2021 by Olivia Siri.

All year round.

A graduate of ENSA Paris Val de Seine, her work is characterized by an authentic aesthetic that reinterprets the Mediterranean context to produce coherent architecture, with clean lines and sensitive, poetic atmospheres.

Olivia Siri Architecture is characterized by a delicate, authentic aesthetic, strongly influenced by the local Mediterranean context in which the agency develops.

Olivia Siri brings to her architecture a genuine balance of natural elements, using raw, essential and sustainable materials extracted from her native region. This balance is complemented by the notions of path and light inherent in traditional Japanese architecture, which she discovered on her travels and which arouse strong emotions in her.

Olivia Siri Architecture brings together a range of collaborators with diverse experience in both private and public sectors, site supervision and environmental issues. These combined skills enable the agency to grow and consolidate in order to respond efficiently to the needs of each project.
