I do have the book, but i found two layers with the studwork the same depth as the rockwool, worked really well for sound proofing and sound treatment. Id certainly do it again. The problem with chicken wire on the inside is simply you need to choose fabric carefully for long good looks if you want it to look nice.

the fabric in my first attempt was glued to the chicken wire. I brushed on adhesive to the wire and attached the rathe nice, but thin fabric. It looked great for six months then started to gently sag, revealing the squares of the wire. I did the same with much heavier bolton twill and that worked much better. 
 

never done the cutting in version. I dont think it would be that bad if you can measure and cut accurately. I know it would not be a good one for my skill and oatience patience

Not sure if it's clear in the diagram but the sheathing is the external wall of the building.

The main problem I see with this is that it seems impossible to add the drywall layer(s) after the sheathing is on, unless it's possible to build the drywall / rockwool framing in nearly-complete sections before placing them.  Otherwise it's nailing the drywall to the inner frame reaching between the studs of the outer wall, then nailing on the sheathing.  This precludes adding isolation treatment incrementally between sound level testing, which kmetal advised to control costs.

Paul, you mentioned in another post that you're working with 9' ceilings for video work.  I was planning on 12' to meet Gervais's definition of a "large room", but perhaps the advantage there is more relevant to music recording, rather than filmmaking?

>bolton twill

I've used burlap to cover OC703 panels, and craft felt to cover rockwool set in large standing gobos (the cats wreaked some hell on those).  I was thinking of just going with the chicken wire initially in the interest of affordability.

I'm going to find an architect next week to draw up plans for a handful of alternative construction scenarios with cost estimates.  Hopefully one of them will allow for a large enough space to make it worthwhile, yet affordable with some DIY.

My 9ft is the building. The killer is that some of my lights are deep. I have scaff tube as close to the ceiling as i can get, but its tight. The saving grace is most of my work involves sitting. I dont need very wide shots so can just get away with feet to top of head. The acoustics actually work pretty well because the only treatment is multiple layers of cloth. I have black, white, blue and green cloths and they all hang permanently on three sides, and do a surprisingly good job. Behind on two sides is storage, so a bit of free air space before the solid walls. I did not intend doing audio work, but i can.
