📊 Key Factors Influencing Prefab Home Prices in London, Ontario (2025)
1. Size, Floor Plan & Module Strategy
In London, Ontario, more square footage and complex architectural forms increase costs through:
Longer factory production times.
Additional craning and transport requirements.
Extended onsite assembly.
🛠️ Ontario prefab builders’ 2025 pricing bands reflect these realities — for example, a simple 1,200 sq ft bungalow costs less per sq ft than a multi-module, two-storey design with multiple rooflines.
2. Materials & Finishes
Material choices can move a prefab home from budget to luxury pricing:
Lower-cost options: Timber frame modules with standard cladding and vinyl windows.
Higher-cost upgrades: Bespoke exteriors, imported cladding, engineered hardwood, and floor-to-ceiling glazing.
💡 Switching from mid-grade to premium finishes can increase total project cost by tens of thousands to over $100,000, depending on scope.
3. Energy Performance & Efficiency Standards
Homes built to ENERGY STAR® for New Homes (v17) or CHBA Net Zero/Net Zero Ready standards require:
Superior insulation and airtightness.
High-performance HVAC and heat recovery systems.
Advanced window and door assemblies.
⚡ While these features add upfront costs (often $15–$30 per sq ft), they can reduce annual energy bills by 20–50%, delivering long-term savings.
These are benefits that discerning prefab home buyers in London, Ontario increasingly prioritize.
🔍 If you’re exploring options for eco-friendly, energy-efficient housing, our expert-curated guide to sustainable prefab homes in London covers everything from design features and costs to financing.
4. Site Conditions & Service Connections
London, Ontario lots vary widely — and so do preparation costs. Expect higher expenses for:
Narrow or hard-to-access sites requiring specialized cranes.
Long service runs to connect water, sewer, or hydro.
Poor soil conditions needing engineered foundations.
Winter excavation, which adds both time and labour costs.
📚 Regardless of prefab or traditional build, the City of London’s permit and inspection process applies.
5. Compliance & Certification
In Ontario, CSA A277 factory certification ensures modules meet the Ontario Building Code (OBC) before leaving the factory.
London and other municipalities recognize A277 compliance, reducing re-inspection requirements.
Some jurisdictions (e.g., Toronto) are streamlining building department processes to rely more heavily on A277 documentation, expediting approvals.

⚖️ Prefab vs. Site-Built: Where You Save—and Where You Don’t
Faster On-Site Timelines
Prefab homes—whether built from modules or panels—typically require only a few weeks on site for setting and finishing after the factory build.
In contrast, traditional site-built homes can take several months to complete entirely on location.
More Predictable Costs
Cost per square foot in prefab construction usually shows less variance, especially when using standard floor plans.
Traditional custom builds often have a wider price range due to design complexity and variable site conditions.
Consistent Quality Control
Prefab projects benefit from rigorous factory QA processes meeting CSA A277 and Ontario Building Code (OBC) standards.
Traditional builds rely on on-site inspections to verify OBC compliance, which can vary depending on site conditions and trades.
Superior Energy Performance
Many prefab homes are built to ENERGY STAR® or Net Zero targets, offering predictable efficiency outcomes.
In traditional builds, energy performance varies greatly depending on the builder and specifications.
According to energy program data, ENERGY STAR® homes are about 20% more efficient than code-built homes, with Net Zero designs delivering even greater savings.
