Teleporting using a second exit and entrance "hard to explain"

[TheJollyCrack]

I'm trying to create a alternative entrance and exit for a room for the player to teleport in and out of. The entrance is going to be outside of a second house that's going to appear to be the outside of the first house in a later period of time while the first house's interior will remain the first house's interior but appear to be the second house\s interior. I don't want to recreate a second room but I want to keep the outside the same so I created an outside duplicate of the outside of the first house.
I've already created the teleport for the in and out of the first house but I'm trying to create an another teleport in front of a secondary house that has no interior so I'm going to use the interior of the first house but use an alternate exit.
I want the alternative exit to exit the player in front of the second house

If this set up is for a MP game i can't see it working correctly but for a SP game it should work if when the player walks into a trigger for teleport 1 entrance and exit on teleport 2 are deactived and vice versa if player walks into trigger for teleport 2 entrance and exit on teleport 1 are deactived
