New Home Build with Dedicated Room

[jmw31]

Not sure if this is the best location for this on the site so please move as appropriate.

I will be moving to a newly constructed home in October and part of the build is a 23' x 17' x 9' dedicated listening room.

This is not a true custom so I do not have a lot of wiggle room for changes.

The dimensions were the best I could come up with living within guidelines
I am going to add 2 20amp circuits - one mid on the short wall and one on the long wall so I have options to move electronics
I am also going to add an outlet in the ceiling in case I make this a 2 channel/AV room.
2x4 construction. Rug/8lb pad over concrete.
One small 1' x 2' in the back third of the room
One door 3' from back wall
Type 1 Whole house surge suppression (Sycom T1 Series)
4-6 LED cans in the ceiling

No plans to upgrade my system next year.

Any build suggestions are welcome.
Thanks in advance,
Joe
