New Studio/Music Room

I am currently converting a small outbuilding to accommodate my modest studio setup. The outbuilding is of brick construction with an uneven brick floor and has a corrugated roof on top.  It has single doorway and no windows.  I would like to achieve reasonable isolation as the building is pretty close to the house.
