Is there a type of unbuildable terrain where you can place buildings on during the game. The person doesn't build it but when a trigger is activated a building gets created on the terrain. (unbuildable terrain) The building should be functionable as well. EX: photon cannon /w enable doodad state.
You could have invincible hidden burrowed units all over a buildable terrain, then remove the burrowed units when you want them to be able to build on it.
This is probably the best solution. There are other methods, but this one is the most unvisable method i can think of.

?? I want to build over unbuildable terrain. But the probe or w/e doesn't actually go and build. Once a trigger is activated a building will appear on the unbuildable terrain and works. I need this because I am doing a map and when the trigger is activated there is a "Warning: Photo Cannon is unplaceable" I figure if there is way to build on unbuildable terrain, than it would allow it.
Don't think it's possible to create anything on a terrain nothing can stand on unless it's built in at the start of the game...
ADDITION:
Well... what you CAN do is have the buildings already there at the start of the game, but have it owned by an unused computer. When certain conditions are met, you can give the buildings to human players.
That could work but how would I don't think its possible to be exactly at the location the person is at. EX: A Probe. Once the trigger is activated, the buildiing will be near the probe. I am already using center view/move location triggers.
