What type of structure did the buyer plan to build on the property?

The answer indicates that the buyer planned to build a storage shed on the property. A storage shed is a practical structure typically used for housing tools, equipment, or other items that require protection from the elements. This type of structure is often smaller and may serve various purposes, such as providing extra storage space for gardening supplies, outdoor equipment, or seasonal items, which can be crucial for homeowners looking to organize their property efficiently.

The other options, such as a garage, barn, or greenhouse, imply different uses and dimensions. A garage typically accommodates vehicles and requires more space and potentially a foundation and electrical work. A barn usually suggests a larger space for livestock or equipment storage, often seen in agricultural settings. A greenhouse focuses on growing plants and needs specific climate control features. Each of these options serves distinct purposes and requires different considerations regarding design and construction, making the choice of a storage shed particularly suited to a variety of practical needs without the complexities associated with the other structures.
