Prefab Homes in London, Ontario — Top Reasons Homebuyers Are Choosing Smarter Building
In London’s competitive housing market, more homeowners are choosing prefabricated houses for their next beautiful home.
Built in a controlled environment and assembled on-site, today’s quality homes offer predictable timelines, energy efficiency, and design flexibility — all while meeting or exceeding the Ontario Building Code.
With over 25 years of experience delivering modular and prefab housing solutions across Ontario, our design team follows proven construction methods.
We use innately detailed construction drawings to ensure every home meets the highest standards for safety, comfort, and long-term value.
1. Speed & Predictability With Modular Home Construction
With modular construction, factory production of your prefab house happens at the same time as site preparation — including foundation and utilities — cutting months off the building process.
Many London builds are completed in 3–6 months after permits are issued, depending on size and specifications in square feet.
2. Energy Efficiency & Green Building
Precision assembly in a climate-controlled facility reduces air leakage and waste, supporting Green Building practices.
All new housing solutions in Ontario must meet OBC SB-12 energy compliance paths, documented in your permit set — see Publications Ontario for details.
3. Lower Risk & Peace of Mind
Weather-protected construction methods minimize delays, reduce costly change orders, and provide greater peace of mind for buyers.
Controlled factory conditions also improve quality control, ensuring your own home meets the highest standards.
4. Design Flexibility With Modular Housing
From tiny homes to large custom homes over 3,000 square feet, modular housing supports a wide range of styles — including contemporary, traditional, and sustainable designs.
Buyers can select layouts, finishes, and housing solutions to fit their lifestyle, from efficient starter models to expansive family residences.

Types of Prefab Homes in London, Ontario — Modular, Panelized, and Custom Options
In London, Ontario, homebuyers looking for their perfect home can choose from several types of prefabricated housing options.
Each type is designed to meet the Ontario Building Code, offer lower costs, and deliver a beautiful, livable space with precision-built quality.
Whether you value affordable housing, sustainable living, or a luxury design with natural light and high-tech features, there’s a solution to match your needs.
At My Own Cottage, we offer proven construction methods used across North America.
We’re ensuring every prefab house we deliver comes with detailed construction drawings, strict quality inspections, and a commitment to energy efficiency for lasting comfort and value.
1. Modular Houses (CSA A277)
The most common prefab choice in North America, modular homes are built as sophisticated 3D modules in a controlled environment.
Each unit is completed indoors, inspected for quality, and shipped to your lot, where it’s joined on-site.
In Ontario, modular home builders must meet CSA A277 standards for factory quality control and compliance.
Once delivered, local building inspectors verify that all on-site work matches construction drawings and meets municipal requirements.
📌 Pro Tip: See the Canadian Home Builders’ Association for official modular housing guidelines.
2. Panelized Homes
Panelized construction delivers pre-cut wall, floor, and roof panels directly to your site for rapid assembly — often reaching “dried-in” stage in days.
This method is ideal for rural areas or seasonal builds, where speed matters to protect against weather delays.
Because they are lighter to transport than full modules, panelized systems can reduce logistical costs while still delivering quality homes with efficient interior design layouts.
🔍 For rural builds or vacation properties, many homebuyers choose smaller modular layouts. Explore our selection of prefab cottages in London built to Ontario Building Code standards, blending timeless charm with modern energy efficiency.
3. Luxury & Custom Modular Home Built in London, Ontario
For buyers seeking a perfect home that combines beauty and efficiency, luxury modular designs can include vaulted ceilings, floor-to-ceiling windows, and premium high-quality materials.
Work with our design team to create a custom interior design with natural light, sustainable living features, and smart home technology.
These builds meet industry-standard tolerances and can significantly reduce build timelines compared to traditional luxury homes — often resulting in lower costs without sacrificing style or performance.

Prefab vs. Manufactured Homes in Ontario — Key Differences, Standards, and Buyer Considerations
When planning your dream home in Ontario, it’s important to understand the difference between modular houses and manufactured (mobile) homes.
While both are types of prefabricated houses, they are built to different standards and have different implications for financing, insurance, and resale value.
Our team has guided hundreds of Ontario homebuyers through this decision, using detailed construction drawings, proven building methods, and up-to-date knowledge of Ontario Building Standards.
All to ensure every project meets the highest safety, quality, and comfort requirements.
1. Modular Homes (CSA A277)
Also called modular houses or “true” prefab homes, these are constructed as large sections in a controlled environment and then assembled on-site, much like traditional site-built homes.
They meet the Ontario Building Code and CSA A277 factory certification requirements, which ensures quality, safety, and long-term durability.
This gives homeowners peace of mind knowing their own home is built to the same standards as any conventional house.
2. Manufactured/Mobile Homes (CSA Z240 MH)
Manufactured homes are built to the CSA Z240 MH standard, which is different from the Ontario Building Code.
They are often placed on a steel frame with a permanent chassis and can be relocated.
While they can offer the best prices per square foot for family homes, lenders, insurers, and appraisers treat them differently than modular or site-built homes.
This can impact mortgage approval, insurance coverage, and resale value.
Why It Matters for Homebuyers in London, Ontario
Financing: Many banks and credit unions require CSA A277 compliance for standard mortgages.
Insurance: Coverage options can vary between a prefab house and a manufactured home.
Resale Value: Modular homes often appreciate like traditional houses, while manufactured homes may not.
Living Space: Modular construction allows for a wider range of living room layouts, home projects, and customization options.
Pro Tip: Always confirm your builder’s certification and review their website for detailed specifications. For official definitions, visit MHAPrairies.ca.
