Sounds like a pretty good idea :-) The slanted roof is a plus too. However the presumably suspended floor would be a negative.
I would suggest getting a few estimates from local contractors on pouring a slab and putting up a "genuine" addition - you might find that it would be cost effective compared to the prefab. Put in a entry door from outside this way you will not disturb the wife on those late night listening sessions.
Do a little research on room dimensions etc. and don't skimp on electrical installation and insulation.
I converted our garage to my private listening room to avoid disturbing the kid's and wife in the evenings. That by the way, involved building a shed to house all the the stuff that normally gets stored in the garage, living in Souther California the cars are fine in the driveway.
Best of luck on your project
