Home extension

What is a home extension?

A home extension consists of expanding the living space of a house by adding new square footage. This can involve extending the structure outward, upward, or creating new rooms to improve comfort, functionality, and property value.

A home extension can include:
Adding a new room (bedroom, bathroom, office, etc.)
Extending the kitchen or living room
Building a second floor
Expanding the basement or foundation
Adding a garage or covered space
Enlarging the home to increase usable area

Because an extension affects the structure of the building, it typically requires:
Architectural design to plan the new layout
Structural engineering to ensure stability
Permit plans for municipal approval
Proper foundation work depending on the scale of the extension

A well-designed extension allows you to increase space without moving, while ensuring the project meets Québec’s building code, structural requirements, and all municipal regulations.
