Should You Extend Your Home? A Montreal Homeowner’s Guide
At Groupe Anthem, we help homeowners throughout Montreal evaluate this decision with clarity—guiding them from planning to design to permit approval, and straight through to construction. Here’s what you should consider before making your choice.
Is Your Property Suitable for an Extension?
Montreal zoning bylaws vary significantly from borough to borough. Factors like lot coverage, setbacks, heritage overlays, and maximum building heights will determine what’s possible.
At Groupe Anthem, we start with a feasibility study to confirm:
What the city will allow
How much area you can add
Whether a vertical or horizontal extension makes more sense
How the extension will impact your structure
Understanding these constraints early prevents costly surprises later.
Be clear, be confident and don’t overthink it. The beauty of your story is that it’s going to continue to evolve and your site can evolve with it. Your goal should be to make it feel right for right now. Later will take care of itself. It always does.
What Is the Condition of Your Existing Structure?
Older Montreal homes—especially in neighborhoods like Ahuntsic, Rosemont, and Villeray—often require structural upgrades before adding new loads. During our planning phase, we assess:
Foundation strength
Existing framing
Roof and floor systems
Insulation and energy performance
This ensures your extension is not only beautiful, but also safe and durable.
Are You Ready for the Process?
An extension involves several stages:
Concept planning
Architectural design
Structural design
Permit approvals
Construction coordination
