The first and most important factor to consider is the purpose of your choosing prefab cabins in Ontario. Are you looking for a seasonal vacation home, a guesthouse, or primary residence? Your intended use will directly influence the size, design, and amenities you should look for in your cabin. If it’s for weekend getaways, a smaller cabin with minimal features may suffice. However, if you plan to live in the cabin year-round, you’ll need more robust insulation, heating systems, and a greater focus on comfort and durability.
