9 Key Factors Affecting the Price of Prefab Homes
1. House Type and Design Complexity
Standardized housing types (such as modular or panelized homes) are less expensive, while fully customized designs (such as curved walls, special structures) can significantly increase costs.
2. Material Selection
Lightweight steel frames are more durable than traditional wood but more expensive, and the price difference between composite flooring and solid wood flooring can be 30%-50%.
High-end insulation materials (such as aerogel) are 2-3 times more expensive than ordinary glass wool.
3. House Size
The total cost increases with the size of the area, but the unit price per square foot may decrease (a benefit of large-scale production). For example:
- 800 square foot cabin: unit price $200 → total price $160,000
- 2,000 square foot home: unit price $180 → total price $360,000
4. Geographic Location
- Shipping costs: For every additional 100 miles from the factory, shipping costs may increase by $1,000-$3,000.
- Local regulations: Some areas require higher earthquake or wind resistance standards, resulting in higher material or design costs.
5. Energy efficiency ratings
Homes that meet LEED or Passivhaus standards will cost 10%-20% more upfront, but the long-term energy savings will offset the cost.
6. Additional features
- Solar panels: $15,000-$25,000
- Smart home system: $5,000-$10,000
- Custom cabinets or high-end bathroom fixtures: The cost may double.
7. Foundation and site conditions
- Flat land installation costs about $5,000-$10,000, and sloped land requires additional reinforcement, which can cost $20,000+.
- Soil testing or special drainage systems: $2,000-$5,000.
8. Manufacturers and Supplier
Prestigious brands (such as Dvele or Blu Homes) have a premium of about 15%-30%. The prices of raw materials, including steel and wood, are influenced by the supply chain. In 2023, the fluctuation of wood costs in North America will cause the price of prefabricated houses to increase by 5%-10%.
9. Market demand and seasonal changes
Prices may rise during peak demand periods, such as spring and summer, and may be more competitive in autumn and winter when demand is lower. In addition, as the market demand for environmentally friendly buildings increases, prefabricated houses using green building materials and technologies may have additional costs.

The construction process of prefabricated houses and their cost
The construction process of prefabricated houses includes several key stages, and the costs of each stage affect the total cost.
Design contract (5%-10% of total cost): This is the beginning stage, where you reach a design agreement with the manufacturer. Standard designs are cheaper, and custom designs will increase costs, accounting for 5% to 10% of the total cost.
Factory production (50%-60% of total cost): All parts are produced and assembled in the factory, usually accounting for 50% to 60% of the total cost.
Transportation (5%-15% of total cost): The cost of transporting the components of the prefabricated house from the factory to the construction site is usually 5% to 15% of the total cost. The cost will be higher when the distance is long and the logistics are complicated.
On-site installation (20%-30% of total cost): This includes infrastructure construction, installation and facility connection on site, accounting for 20% to 30% of the total cost.
The impact of timeline on cost
Fast construction can save loan interest and other expenses, but if expedited production is required, additional costs may be added. Expedited production involves higher expenses, such as accelerated factory production, special shipping and installation arrangements. Therefore, balancing fast delivery with cost is key.
