Sujets Objets (SO/) is an architectural practice based in Geneva, founded in 2020 by Dafni Retzepi, Thierry Buache, Charline Dayer, and Philippe Buchs.

As an office, they place great value on what is already there — built or unbuilt — working closely with the existing context and exploring how minimal gestures can produce maximum effects.

While architecture is often seen as a product-oriented discipline, SO/ challenges this notion by using the process of making a project as a field for experimentation and engagement.

For SO/, the act of building is not a final goal but part of a continuous transformation that begins on the very first day of the project. Each site becomes a laboratory where the practice tests alternative ways of producing spaces, often through 1:1 scale prototypes that question conventions and norms.
