Shell of the Building

The shell of the building, including the metal roof, walls, and insulation, can range from $10 to $20 per square foot. This can vary depending on the size of the barndominium, the complexity of the design, and the quality of the materials used.

For instance, a 2,000 square foot barndominium with a basic design and standard materials might cost around $20,000 to $40,000 for the shell, while a larger, more complex 4,000 square foot barndominium could cost around $40,000 to $80,000.

Interior Finishes

The cost of interior finishes can vary greatly depending on your personal preferences and budget. On average, interior finishes can account for about 30% to 40% of the total cost of building a barndominium.

For example, a 2,000 square foot barndominium with mid-range interior finishes might cost around $60,000 to $80,000, while a larger, more luxurious 4,000 square foot barndominium could cost around $120,000 to $160,000.

When planning to build a barndominium, it's essential to consider these factors and costs. However, it's also crucial to remember that building a home is a personal journey, and the value of a barndominium extends beyond its monetary cost. It offers a unique living experience that combines the best of both worlds - the charm of a barn and the comfort of a modern home.
