Bâtiment Préfab

Bâtiment Préfab manufactures panelised building kits at 5650, rue Lamoureux in the Théo-Phénix industrial park in Saint-Hyacinthe, Montérégie, with a second sales office serving the Quebec City region by appointment (https://batimentprefab.ca/nous-joindre/). The company is explicit that it makes kits rather than complete modules: "Notre produit : Construction en kit (panneaux)" — walls in pre-insulated panels, floor joists and rafters built in the factory and delivered to site with all the assembly hardware, with doors, windows, exterior cladding and roofing generally included but interior finishing excluded (https://batimentprefab.ca/avantage-prefabrique/). Its exhibitor entry for Expo habitat Québec, held 5-8 February 2026, states "Depuis 19 ans, nous réalisons des rêves" and more than 700 prefabricated buildings completed (https://expohabitatquebec.com/exposants/batiment-pre-fab/). Le Courrier de Saint-Hyacinthe reported the company's move into the Théo-Phénix park; its own blog post covers the inauguration of the roughly 7,000 sq ft Saint-Hyacinthe production plant (https://batimentprefab.ca/blogue/lentreprise-batiment-pre-fab-inc-inaugure-ses-nouvelles-installations-de-production-a-st-hyacinthe/).

The mini-home range spans 488 to 964 square feet and is sold under named models — Abri 550-BV1 (488 sq ft), Refuge S560 (560), Otimo (636), Optima (678), Abri 750 BV (709), Refuge S825 (825), Rüstik (500) and Vitä (964) — alongside separate lines for micro-homes, chalets, full houses, garages and solariums (https://batimentprefab.ca/minimaisons/, https://batimentprefab.ca/). The site publishes an inclusions-and-exclusions page setting out exactly what a kit contains, plus financing-free pages on services, FAQ and the case for kit over modular construction (https://batimentprefab.ca/inclusions-et-exclusions/). Contact is 450 339-4002 for Saint-Hyacinthe and 418 476-0122 for the Quebec City sales office.
