The Atelier d'architecture Seydoux is the result of a very close collaboration between Laetitia Berger and Marc-Olivier Seydoux, both architects, graduates of the Swiss Federal Institute of Technology Zurich (ETHZ) and members of the Swiss Society of Engineers and Architects (SIA). Transforming and renovating while preserving the identity and essence of the building, extending and building while harmoniously integrating into the site are the mottos that guide us in the development of our architectural projects. The central idea is to create spaces in perfect harmony with their occupants. Indeed, we place their comfort and well-being at the heart of our concerns, which is why the projects evolve in close collaboration with the client. Ambiences and emotions are the foundation of each of our projects and are created by staging spaces that differ in their proportions and in their relationship to light. The importance we attach to finishes and the choice of materials pushes us to innovate, in order to preserve the authenticity of our architecture, which is as modern as it is original. Ultimately, we imagine sustainable solutions, so that the building adapts to its users over time and makes them feel good. Translated with www.DeepL.com/Translator (free version)
