Bath College. This is where the character will be at work from the start. The room in this picture is where he gets teleported back to when the headphones are unplugged.

This is the room he could be at home from. I need to have a discrete room not too branded in 'Bath College' signs. So I can consider this room an option. The part he is at home for is really in it for only about 3 seconds when he is handed his headphones.

This is the hallway he is greeted at by his friends and colleagues in one of the quick cutaways.

He gets teleported outside the college for the first time. Then he always goes back to college where the headphones are unplugged.

Up to down of the Bath Abbey. The second location he is teleported to.

This is Pultney bridge the third location he is teleported to. Except he will be on the path right by the river. This angle gives you a better perspective of his surroundings, however. 

The fourth location is in the countryside where the trick stops working and can't teleport back to work and the film ends with his frustration.
