Luxury renovation vs custom build; which costs less in Toronto?
In 2026, the answer depends on scope, structure, and long-term value not just upfront price.
Many Toronto homeowners start with a renovation plan, only to discover that a custom home build offers better value, fewer surprises, and stronger resale potential. This guide breaks down costs clearly and helps you decide which option makes financial sense for your property.
Luxury Renovation vs Custom Build
In Toronto, a luxury renovation costs $400–$600+ per square foot, while a custom home build costs $350–$650+ per square foot in 2026.
When renovation costs approach custom build pricing, building new often delivers better value, layout flexibility, and long-term efficiency.
What Is Considered a Luxury Renovation?
A luxury renovation involves upgrading an existing home with high-end finishes and structural changes while keeping the original structure.
Luxury renovations often include:
-
Full interior gut
-
Structural wall removal
-
High-end kitchens and bathrooms
-
New HVAC, plumbing, and electrical
-
Layout reconfiguration
In older Toronto homes, renovations frequently uncover hidden issues that drive costs higher.
What Is a Custom Home Build?
A custom home build involves demolishing the existing house and building a new home from the ground up.
Custom builds allow for:
-
Fully optimized layouts
-
Modern ceiling heights
-
Energy-efficient systems
-
Better structural integrity
-
Lower long-term maintenance costs
This option offers greater cost predictability when planned properly.
