Your Expert Guide to Permanent Prefab Living in All Four Seasons
But is it realistic to stay comfortable through a -30°C blizzard or July humidity?
The short answer: Yes—if it’s built right.
Let’s walk through what makes a prefab cottage suitable for permanent living, with tips from real homeowners and insights from leading cottage builders.
✅ What Makes a Prefab Cottage Suitable for Year-Round Living?
Unlike rustic cabins or basic vacation homes, today’s prefab homes (also called modular homes) are engineered to meet or exceed Ontario’s building codes for permanent dwellings.
Key Year-Round Features:
Insulation (R-value): Wall and roof insulation is typically upgraded to R-24+ and R-60 respectively for energy efficiency.
High-performance windows: Double or triple-glazed windows reduce heat loss and drafts.
Four-season HVAC systems: Heat pumps or hybrid furnaces paired with HRVs keep air fresh and warm.
Skirted and insulated foundations: Essential for cottages on piers or crawl spaces to prevent frozen pipes and heat loss.
📍 Pro Tip: Ask your builder if your prefab meets CSA A277 or Z240 standards. These certifications ensure compliance with residential codes and make mortgage approvals easier.
🏡 Real Stories: Living the Prefab Dream in Ontario
When Michelle and Carlos relocated from the GTA to their custom prefab home near Haliburton, they expected trade-offs.
Instead, they found comfort, savings, and beauty.
“Our home model from Myowncottage.ca is 1,100 square feet, open-concept, and perfectly winterized. We’ve been through -32°C and were cozy the whole time. The living room even has better natural light than our Toronto condo.”
As their builder, we included energy recovery ventilation, premium insulation, and a Passive House-inspired design—all inside a controlled environment that prevented construction delays and weather damage.

✅ Use a heated water line or heat tape for pipes
