Finished the stereo house December 2019. Took six months building it and literally 5 years to research all angles to plan for it. Construction is concrete pad, offset stud walls one foot thick, double sheets 5/8" drywall with green glue sandwich. Ceiling is same sheetrock construction but mounted on metal furring hat channels with sound clips. Used 71 cartridges of compound and 21 sealant. All electrical outlets backed with soundproof putty.
Two small windows 4" thick with triple pane. 3" thick solid wood door, mahogany on outside, pine inside. Whisper quiet mini split AC/heat wall mounted unit.
Result is stunning, I hear nothing from the outside, trash truck included, and no one hears a peep of my music from the outside, no matter how loud.
Mission accomplished for sound proofing. For acoustic treatment I worked with Gik and the results are phenomenal. It took me 3 months to tweak in the system and now 6 months later I have completely stopped tweaking anything. Happy and satisfied music lover here with what I accomplished. The construction was nerve wracking at times since no one around this area was familiar with this type of construction, but I really enjoyed guiding those guys along. Great experience. In the process of upgrading some equipment, pictures will follow. Ended up doing a bunch of acoustic treatment upgrades also. Reality is the journey is never over no matter the level of quality. Lesson learned :)

Gik acoustics 8 corner bass traps, 4 absorbing panels for side walls, 2 for front wall and 2 absorber/diffuser panels for back wall. Later added diffusers for first reflection points, back wall, rear side walls and ceiling for a diffuser surface total of 84 sq. ft.. The total surface of absorbers amounts to 72 sq. ft. plus the floor to ceiling bass traps in the 4 corners.
Once I got rid of all echoes with the absorbers, it took that many diffusers to open up the room and give it the lively sound I lost with the absorbers. Now I have no echoes and a lively room! What a trip!

Well done @baylinor. I see that you used the "golden ratio". I am considering that same size IF I build on this summer. Honestly, that is questionable. I am a retired builder but will be 70 yrs old and not sure I have the stamina to do it. Oh well, my system sounds great in the LR and wifey likes it too so its hard to say. All the best to ya.
BTW, What is the purpose of the hat channels with the wooden framing? Just curious.
