Modular construction in Mont-Saint-Hilaire

As elsewhere in the La Vallée-du-Richelieu MRC, residential projects in Mont-Saint-Hilaire most often happen on private land — the context where the modular approach makes the most sense. The home is factory-built, sheltered from the weather, then transported and assembled on a permanent foundation, reducing time spent on site accordingly.

The total cost of a project in Mont-Saint-Hilaire depends on the land, foundation, connections (water/sewer or well/septic) and transport to the municipality, on top of the building itself. Once set on a foundation, the home finances like any other property.
