Building recognition in vuforia?

Question

normally I can make apps using image targeting or cloud recognition but now I need to use physical buildings as target so my question is does anyone know how to recognize buildings via vuforia + unity or vuforia android?

I found an app in youtube and just want to know how it should be created.

With Vuforia, you need to provide "Target image" for the recognition and load the target database in Unity. It's possible to take a photo of the building and use it as a target. But you need to take only a photo of something that won't change over time (ex: tree, vegetation, etc.)
