The addition of a second floor
What is a second-story addition?
A second-story addition consists of adding an entirely new floor on top of an existing house.This type of project significantly increases the living space without expanding the footprint of the home. It is a structural transformation that requires careful planning, advanced engineering, and full compliance with Québec building standards.
A second-story addition can include:
Adding bedrooms, bathrooms, or a master suite
Creating an office, family room, or additional living space
Redesigning the home’s layout to improve comfort and functionality
Reinforcing or modifying the existing structure to support the new level
Updating the architecture to ensure a harmonious and modern look
Because the new floor adds weight and structural loads, this type of project requires:
Structural engineering calculations
Architectural planspermit plans approved by the municipality
Foundation verification to ensure capacity
Reinforcement of beams, walls, or flooring
A well-designed second-story addition increases property value, improves comfort, and adapts your home to your evolving needs — all while preserving the land around your property.
