Johan Wijesinghe is an designer and researcher.
He has led projects across North America and Europe with a focus on mass timber, digital tooling, and regulatory adoption.

He collaborates with Escher GuneWardena on cultural projects and historic conservation. As a Visiting Lecturer at ETH Zürich (2024–2025), he co-led Architecture in Large Quantities with Gilles Retsin—a studio exploring prefabrication, the supply chains and business models that enable it, and AI-driven design workflows. Educated at University College London and the Southern California Institute of Architecture, he translates applied research into systems that scale sustainable construction.
