I'm glad for you that you're so wealthy

I'm not particularly wealthy - and my personal finances have nothing to do with this thread. You asked who. I told you. There's no reason at all for you to be condescending.

I'm not giving bad advice, ND. OP can ignore it and do whatever he wants.

You can too.

To whom it may concern..

I have two identical rooms, both 16x10 that I want to turn in to control / drum rooms. They are in the middle of a church building.

There is the MAIN clue. IN THE MIDDLE! I've seen things like this. People get together and decide partition off some space on an upper floor with NO regard for support walls below or even if the joists will support the possible live/dead weight . They just do it. And if you do it without permits..in the event of ANYTHING happening...you run the risk of not only injury, but FINES and even loss of insurance. This is why I opened this can of worms.

Think about this. Simply adding ONE layer of 5/8" drywall to the walls in each room will add roughly 1830 lbs(about 26 sheets of 4x8 5/8" drywall at 70.4lbs per sheet). This doesn't even include the floor, or equipment..AND PEOPLE!

And I wasn't. But seeing as you mention financial perspective, I earn a national average salary and my car cost me £5k and will take years to pay off. I don't own ten thousand pounds' worth of belongings in total. Don't make out that spending well over tens of thousands on one's hobby is normal, mate, if the only option for keeping the noise down was going to cost $38k I simply wouldn't make music any more.

With that said there IS some good advice in this thread, it's just disappointing that people needed to alert the mods to it (and not just one person either).

Alert the mods? For what? Hmmm, did someone get hims little feelings hurt or something? Other than that I don't get it.

I already explained the reasons for the $38k estimate. But for your sake I'll say it again...anytime you want somebody to estimate modding a couple of rooms on an upper floor...and you don't have a clue whats supporting the floor OR what the target Transmission Loss is....BUT..you tell the person estimating it..."The main concern is isolating the rooms from everything around"I submit you have to guess high. Even then your spittin in the wind. I only tried to point out what he was up against to MEET THE STATED GOAL! However, your right. MOST people here would have to forgo building a home studio IF they had to spend that much money. However, MOST people aren't trying to "ISOLATE" 2 ROOMS ON AN UPPER FLOOR FROM EVERYTHING AROUND THEM. But if you were...YEA, it COULD cost that much and even more under some circumstances. Thats reality. Live with it.

I'm with Rick here. No, it probably isn't $38K, but Rick didn't say it was. He said that was his highball estimate because the OP refused to provide any details on existing construction. I mean, c'mon, he works for an engineering company? Remind me not to hire them!

And of course it's a commercial space. You just don't screw around with commercial space, you have to get a permit and engineered drawings. What's under the room, the sanctuary?

My guess is $10K in materials plus permits (varies greatly by jurisdiction), with all volunteer labor. Presumably there is a GC and tradesmen in the church who can pull the required permits. Commercial ain't like a home studio where the homeowner can pull permits and even do most of the trade work himself.

Or if this is being rolled into a larger remodel, perhaps there is no marginal cost to permits and economies in purchasing materials, labor, etc. But then we'd just be guessing, and guessing with no real information.

OP got the advice he merited . . .

I think for 3K the best option may be an electric drumkit.

soundproofing question reply

Hi everyone, I am new to this forum. The studio I am building occupies the second floor of a new building. I have double walls and oversized floor, roof trusses. Other members here are correct when stating that $3,000.00 will not accompolish adaquate sound attenuation. Since this is a church, will recording be done at the same time as services? Sound attentuation may not be a concern if there are no services.
Frequencies above about 800hz are the easiest to stop. Below that, only MASS will dampen the sound. I have had good luck with a product called 'Horse Stall Matting'. It looks like recycled auto tires and comes in sheets of 4' X 6' X 1/2" or 3/4". This stuff is god awful heavy and and a pain to install on the walls. BUT it is cheap ..about $45.00 per sheet. I tape the seams with EDPM seam tape. Another product I would recommend is 'Green Glue'. Use it to sandwitch different thickness of drywall. Look for it at drywall suppliers.
Caution ... Structural loads for 2nd floor are usually 100 to 125 lbs per foot static load. It will be fairly easy to exceed that with adaquate sound proofing and recording personel.
Anyway, if I can be of any help, please feel free email me. Check out my web site for further information.
