Trianon Residences

What Trianon Residences does

Trianon Résidences is a French real estate developer founded in 2004 and headquartered in Entzheim, Alsace, specializing in new-build residential properties across the Bas-Rhin and Haut-Rhin departments. The company operates as the flagship residential brand of Groupe Vivialys, the leading housing constructor in Alsace with approximately 1,300-unit annual production capacity and 380 employees. Trianon delivers apartments and grouped houses priced from roughly €167,000 to over €500,000, sold primarily to individual primary-residence buyers and buy-to-let investors through physical showrooms, the proprietary Trianon Store 3D virtual platform, and integrated financing advisory.

The company's technical differentiator is its proprietary 'Bâtiment Sain' (Healthy Building) certification, created in 2014 with medical experts from CHU de Strasbourg and applied across all programs to control indoor air quality and VOC emissions. Complementary proprietary technologies include photocatalytic 'Façades Dépolluantes' (deployed at Heart Déco and Candide residences), the ADEME-co-developed Manag'R air-quality management method, and the WALLIS INFINI modular housing system co-developed with Saint-Gobain. Trianon layers on differentiated services including TrianonProtect (10-year buyer guarantees), Prêt à Imaginer customization across three finish tiers, and the Droit à l'erreur repainting service.

Commercially, Trianon generates one-time revenue per unit sold under the VEFA (off-plan) framework, marketed both directly to consumers and to investors via French fiscal regimes (PTZ, Jeanbrun, LLI, LMNP). Distribution combines a sales-led advisor model with self-serve digital tools; buyer financing is supported through bank partnerships. The company has won multiple innovation recognitions including the 2019 Pyramide d'Argent de l'Innovation and the 2020 ConstruCom Award for the Trianon Store platform.
