The lifespan of a foldable or expandable house depends on its materials, construction quality, and maintenance. High-quality models made with galvanized steel frames and insulated panels can last 15–30 years or more with proper care. Regular maintenance, such as checking for rust, leaks, or panel damage, and ensuring proper installation, can significantly extend the house’s life. Lower-quality or temporary models may last 5–10 years, especially if exposed to harsh weather or heavy usage. Overall, durability is largely determined by material quality, environmental conditions, and how well the house is maintained over time.
