I built a new house a few years ago and had real fun doing a dedicated audio room.
Dimensions are 20w x 30l and 15ft ceiling. Lots of places can give you 'ideal' dimensions for any size room.
Best thing I did was put the room on the ground floor with a poured concrete floor and radiant heating (no sound of heat system, no baseboard etc.) under carpet. I did not put in a baffling system for the air conditioner; on the other hand I don't spend a lot of time indoors with the system in the heat of summer. When the ac is on in summer I do have some increased background noise. Oh well.
I also used 3/4" wall board. I used standard spacing 16" on the frame but have since heard from folks who used a 12" spacing claiming better results.
I did not put in sound proof windows. My builder felt I might not need them and I think he was correct. I do have one window near my a/c compressors which might benefit but I doubt I'll do it (never say never)
I also put in a dedicated a/c panel, hubble outlets and lines. I did not use any fancy in wall wiring (budget consideration). Lighting is all separate from audio. This was a very good idea. System is dead quiet, no hum, no hiss, no line noise... you get the idea.
As you are a carpenter you might think about integrating room treatment into your design. This is one thing I will do the next time I build a house. :)
You might want to contact Rives Audio (www.rivesaudio.com) for assistance. Consulting with a sound engineering firm like this is another thing I think I would do differently.
Live and learn.
One final thing: the doorway between your audio room and house is a critical choice. I lucked out finding a huge double door at a salvage sale. A poor choice here will be heard! (pun intended)
Have fun!
