Modular construction in Westmount

Modular construction in Westmount

The principle is simple: the modules of your future home take shape in a factory, under a roof, while the foundation is prepared on your lot in Westmount. Delivery follows, then assembly on the permanent foundation. On-site work is shortened, and the weather stops being the factor that dictates the schedule.

On top of the building price, a project in Westmount carries off-factory costs: the land, the foundation, the connections — water and sewer, or well and septic depending on the sector — and module transport. That total is what you should compare from one builder to the next. On a permanent foundation, the home then finances like any other property.
