Marginalia is an architecture firm founded in 2017 by Mélissa Vrolixs. The company is based in the heart of La Chaux-de-Fonds in former watchmaker workshops and radiates throughout Switzerland thanks to numerous collaborations and competitions. As part of its local construction and renovation activities, a department for the reuse of materials has been set up. During demolition or construction works, special attention is paid to deconstruct the existing architecture and recycle its elements, whether in the future project or through third parties, thanks to the Salza platform and the company Syphon AG.
