A few years back I finally got a dedicated space to call my own after more than 20 years shoehorned between the furnace and the water heater in the basement of a ranch (single story) house. I was getting underway just before the pandemic hit with some demolition of the previous space, waterproofing and moving a gas line, so not long after we got holed up at home I had a palette of drywall/lumber/supplies delivered. Not the worst time to be shut in.
My ability to make music was quite constrained in my old space, where every note I played echoed throughout the house. This was frowned upon by my family members, and even more so when I got a set of eDrums 11 years ago. Thunkety-thunkety-THUNK!
Thus, my main focus when building the room was to maximize isolation to allow me to play more often without bothering everyone. I have been most pleased with the results in that regard (as has my wife). I got started using general info online about the use of RC-1 and such but ran across the Rod Gervais book after I had gotten underway and shifted gears a bit (still used the RC-1, of course). I took lots of photos of the process if anyone is curious what I did. Happy to start another thread on that. The ceiling was the most important - family room directly above. The weakest link now, bleed-wise, is the door, which is a standard grade exterior fire door.
I did the best I could with my knowledge at the time, skills and budget and chose not to go down the more involved path of determining how much isolation I wanted/needed and figuring out how to get there. I would probably still be trying to figure that out! It worked out fine isolation-wise. I have been learning Reaper and figuring out the work flow to allow me to move around quickly, and it is now time to turn my attention to acoustic treatment. I threw corner bass traps together with left over 3 inch rockwool when I first moved in just to tame things a bit (and that they did), but much more is needed. Debating how to approach that now. The space is about 17 X 11.5 X 7 ft, so a pretty small room as ideal mixing/listening rooms go, and with a very low ceiling to boot.
I wasn't in a position to move the door so the bass trap on the left slides into place:
The soffit above the guitar amp covers an HVAC pipe to the upstairs room. It is an engineering marvel.
I debated tearing out these partial walls but kept them in the end (where would I mount my sconces otherwise?). I did cut out holes in them and put rockwool in there, for better or worse.
