Danish architect Søren Pihlmann, who contributed to the 2025 Venice Architecture Biennale with the “Build of Site” project in the Danish pavilion, will be giving a lecture at Bozar on 31 March 2026 at the invitation of A+. He has developed a practice based on reuse, detailed analysis of existing structures and constant attention to the inherent capabilities of materials. Through his projects, he questions contemporary construction logic, the role of cladding, industrial processes and how architecture can be transformed by working with what is already there. This interview explores a way of thinking about projects where action precedes form and where materiality becomes a critical driving force.

Léone Drapeaud  (A+): In your description of House 14a, you mention a series of actions – exposing, covering, cutting, joining, stacking, casting – used to transform an existing composition. These verbs do not seem theoretical, but almost practical, as if they relate to the building site. I would like to start from there: how do these actions, rather than forms or projects, structure your work and your way of transforming architecture?
