So, the way to solve this puzzle is very limited. You can either do it by the way I will describe, or mirrored.
The stage needs to be in the very far right corner. With 1 space between itself and the well.The lamp needs to be placed directly next to the well on the opposite side of the stage. This works because the well doesn't count as a proper tile, it just prevents you from placing a tile where it sits.
The pavilion needs to be placed in the corner opposite of the well. That way nothing is in its corners.
The gate needs to be places directly next to the pavilion on the left side. This way it doesn't interfere with any other tiles, and its requirement of being next to a tile gets fulfilled.
I hope I was able to help :)
In case anything was unclear, here's an image that shows how to solve it:
