Your conservatory wouldn't place because of the trees. We only see in game the image of the trees. but in the scripting the image is laid on an actual block so your conservatory block was hitting the tree block.
So I figured out the issue later - I had turned down the graphics and it made the ROCKS INVISIBLE!! There was a rock there and that's why I couldn't place it!! Which is just super silly

But I appreciate you mentioning about the trees too because that also definitely could have played a role!
