The Altera Multigenerational Series

Discover our bi-generational models designed to transform cohabitation, where each generation finds its balance between proximity, autonomy, and comfort.

Multigenerational homes

For today’s and tomorrow’s families The Altera multigenerational series, driven by the vision of Harmonie Construction co-founders Maxime Thérien and Maurice Dagenais, was created to meet an essential need: enabling families to live under one roof while achieving the perfect balance between closeness and privacy. Its name, Altera, is inspired by the Latin word alter, meaning “the other,” symbolizing the complementarity of generations. Each model—Origine, Évolution, and Horizon—reflects this philosophy by offering a tailored progression in terms of space, functionality, and accessibility. With Altera multigenerational, intergenerational living becomes a harmonious experience, where each generation maintains its identity and living space.
