Boiler Room Floor Plan

I have produced a floor plan which shows how sound will be placed around the room.

There are also sounds to really help create the boiler room setting such as banging pipes, the humming boiler itself and dripping sounds. The next step for me now is to create a very simplistic environment in Maya to be exported into Unity. The blocking out phase in Unity isn't necessary as the level itself will be very simple anyway, and also, the sound is the most important element here. A quick maya mockup should be enough and then I am on with placing the sounds:
