How do I get an object to stay in an exact location in AR?

So I am trying to get a digital data set (building) to appear in augmented reality infront of me. On a small scale inside a room this was fine, however now I am trying to do it at real scale and between me and the location where I want the building are various partially blocking real world objects (trees, bushes, etc.).

This is causing the building to change in both size and location all over the place because the software is trying to super impose it so that I can always see the entirety of the building.

My question is, how do I make it so that the building ALWAYS spawns at the exact location I have it in the editor, no matter what blocking objects may be inbetween me and the data.
