Storage Buildings and listing them as an asset

I purchased a large storage building for my business that was built on my property. In trying to list it as an asset, there is no category for this type of asset. When choosing add an asset, the only categories to choose from are : 1- computer, video, photo and telephone equipment,  2-  tools machinery equipment and furniture, 3- Real estate property,  and 4-Intangibles, other property. None of these categories seem to work for a storage building. The building is too large to be moved and was built on site. I did run electric to it. It does not have a foundation as in typical building construction but is meant to be more or less a permanent structure.
