Who We Are

A small studio with deep expertise.

Onera brings together architectural design and structural engineering in one team, collaborating with architects, mechanical engineers, geotechnical engineers and builders as each project requires. The result is a more direct conversation, faster decisions, and a project that holds together — on paper and on site.
