New construction in Austin TX

I am nearing breaking ground on a private studio construction here in Austin, Tx. I am designing a stripped down 2 room recording studio where I would like to be able to record a range of music, although the live room at 17 x 21 (14'10" H) will only be about 5200 cubic feet, so no choirs unless we're going "wall of sound" and want to overdrive the room. The control room is 12' 2.76 x 17' with 13'11 ceiling. I am hopeful that this live room dimension will give a good drum sound. As far as loudness, I need to be able to accommodate a loud kit. Of course at some point I will have someone wanting their stack at 11. The structure is 8' behind my house in a neighborhood where houses are 20' apart on 800 sq. ft footprints and people sleep with their windows open (Austin's east side) I am hoping to keep the budget around 25k by doing everything but HVAC and Electrical myself. The foundation I have in mind is a 30" deep perimeter wall with the bottom 12" being a 2' wide footing and the remainder being 1' stem wall. The floor would then be a 4" slab on grade inside the perimeter wall. The footing wall would also span the footprint where the control room/live room divider wall would be. Concrete embedded bolts hold the 8" plates for the 2x6 staggered stud walls. For the outside I am thinking of stucco or hardiplank siding. The inside is looking like 2 x 5/8" sheetrock on resilient channel or some quasi equivalent if I can't find a reasonably priced supplier for RC. Looking to fill the cavity with blown cellulose. Overall wall height is 16'. Room dimensions are derived from 1: 1.14: 1.39 dimensions. I am running electric in conduit on the inside of the walls and there is no plumbing. I am still researching the wall details and looking for cost-cutting alternatives. I expect I will have many questions as we begin construction but at this point I am looking more for review and critique than specific questions answered.

welcome! the loud stuff will be a challenge if you're thinking of going with a single wall approach using only RC on the inside. for cost savings - you might be better off with 12' ceilings - but then you still want an inner isolation room (room within a room) for at least the live room to get enough isolation. the inner isolation room would be 10' ceiling. same for the CR. on the pad, you might consider separate footings for the inner isolation wall support as that isolation room could easily weigh in at 7-8 tons. depending on how loud you mix or want to hype clients, the CR might need to be a room within a room as well.

I have reverted to a 2 frame set construction with a plain old slab. I want to make the roof area habitable with some plants later so I will need to provide significant load for that. The 16' high profile helps to get usable acoustics out of the 36' x 19' footprint, so I am set on that. Here are some other models and pics, the old model with the 2 frame sets and a newer one with some ideas about layout and treatment. Also site photod. I expect to treat the room iteratively, so nothing here is specific, more for visualization. I am looking at ways to use more diffusion with harder surfaces and less absorbtion, a liver sound. I would then add wideband absorbtion from that point in a way that is adjustable to taste (leaving me an option to make the control room as live as possible since it will likely be a tracking room often anyway.) I also need to figure out what needs to go in the floor before I pour a slab. Electric is all on the inside of the walls, and there is no plumbing, so it's just audio cable pipes. I guess...?

more pics. I have more detailed models with framing but cant post them here.

" 2x6 staggered stud walls...The inside is looking like 2 x 5/8" sheetrock on resilient channel ." Staggered studs and RC? The staggered studs is the attempt to decouple the interior from the exterior...the RC will add extra depth in the wall cavity, but there are easier ways to gain the depth without incurring cost or a learning process. Most data shows that there are acoustic holes in wall assemblies that use RC, especially in the low frequency area. A typical staggered stud wall (assuming sheetrock on both sides of the assembly) using one layer of 16 mm or 5/8 inch fire rated rock will yield an STC of 48, @ about 50 Hz the Transmission loss is around 14 and stays flat with not much improvements along the way. A fully decoupled wall assembly, with 13mm or 1/2 inch fire rated rock (READ A THINNER MATERIAL), 16 inch layout yields an STC of 53 (HIGHER by 5 points) and starts with a TL of around 16 and continues into a better region that far out performs the staggered stud with the additional RC.

Yep, I have decided to forget the staggered stud.
