A construction estimate covers hard costs only. It typically excludes: land, building permits, architectural and engineering drawings, interior design, landscaping, and financing costs. In the GTA these soft costs commonly add 15–25% to the total budget.
The biggest cost drivers are: foundation and excavation complexity, structural design, envelope glazing, mechanical and electrical capacity, kitchen and bathroom count, millwork and finish level, and lot-specific conditions such as slope, soil type, or ravine setbacks.
Municipal permit fees for a luxury custom home typically range from $15,000 to $40,000+, not including development charges which can add significantly more in some municipalities. AVL coordinates the permit process and provides estimated fees at consultation.
Major renovations typically cost $200–$400 per square foot for the renovated area — less than new construction per square foot. However full gut renovations of older homes can approach new build costs when structural, mechanical, and electrical systems need replacement. A consultation with AVL can assess which path makes more sense for your property.
