As a company, our passion is to design harmonious and luminous spaces. Alias Architecture was born out of the desire to offer an alternative solution to people who want to reduce their ecological footprint. As a result, we design environmentally friendly spaces that combine comfort and well-being. Committed to ensuring your satisfaction, we also stay up to speed with all the latest innovations in Eco-construction.

Our founder, Lucie Langlois, is also very involved in the field of ecological architecture. She is a member of organizations such as IPHA (International Passive House Association) and the Canada-Quebec CBDCA-QC Sustainable Building Council. She is also the ex president of Maison Passive Québec (2014-2017). Together with Marie-Claude Crépeau, a senior technician, she is one of the first specialists to design Eco-homes in Quebec. These days she continues to innovate and enrich her knowledge through targeted education and training.
