What term describes buildings suitable for only one purpose and incapable of being converted to an alternate use?

The term that accurately describes buildings designed solely for one specific purpose, which cannot easily be repurposed for an alternative use, is single-purpose properties. These properties are typically constructed with specialized features or layouts that cater to the needs of that singular function, making them less adaptable for other uses.

For example, a purpose-built factory may have specific equipment and infrastructure tailored for manufacturing a certain product, rendering it inefficient and impractical to convert into office space or retail establishments. This lack of versatility is a defining characteristic of single-purpose properties.

In contrast, other property types such as multi-purpose and mixed-use properties are designed with flexibility in mind, allowing for different activities or a mix of uses. Flexible use properties also showcase an adaptable design to accommodate various functions over time. These alternative property classifications inherently possess the qualities that single-purpose properties lack, thereby making them unsuitable as answers to the question of buildings that cannot convert to alternate uses.
