Hi everybody! We are planing to upgrade to a bigger and better studio, and build it from scratch in a village near the city. I would like to post here from the first steps (now) till it's totally built. Any help is welcome! This is our first design:

The studio is supposed to support big groups like corals or bands, so the big Room 1. It's supposed to be able to record a rock band playing live, watching themselves. Room 2 is for the battery, Room 3 the vocalist and Room 1 the rest. Hall is supposed to be used as sound lock but big enough to carry a grand piano inside Room 1. The control Room is so large because we want to be able to give a class to 10 - 20 students. Room 2 is going to be a "rest room" for the people we don't want to disturb us when working so they can go there, seat, listen to the music, watch the performance... etc. Acoustically Room 1 is going to be a more or less neutral but with a more reflective side and a more dead side (from left to right). I want Room 3 to enhance a vocal performance so I have to study it, I don't know right now, maybe doing it with not so much absorption and a lot of diffusion to get good early reflections. Any idea is welcome. Room 2 is going to be between neutral and live. We prefer to keep that room useable for any purpose. If somebody wants to get a "very live" sound of the battery then we will probably use the live corner of the Room 1 with more reflective panels (tiles or rock) hanging from the ceiling. Almacen is the store and oficina is the office (obviously). I'm afraid that Room 3 is so small I can't deal standing waves with proper bass traps or the Control Room so much big (too long RT). As I said, any comment is welcome!
I forgot to talk about insulation. The external walls are going to be: concrete + wood studs with fiberglass + air + wood studs with fiberglass + gypsum board + green glue + gypsum board.

nice design! you could consider reversible treatments on the walls of the live rooms and booths. take a look at some of John's designs where he has incorporated reversible treatments. the small booth should be ok for vox and my choice is to be slightly more live than dead so using slat resonators will help balance the room and you could consider a more dead ceiling treatment and reversible hanging absorbers/reflectors. i would make room 2 a nice quality booth and make the hall the lounge for people to hang out. if need be, you could drop the room 3 in favor of the larger hall/lounge. in the CR, if you're going to make it a teaching facility, you should think about the seating for viewing vs active participants - raised level seating in back, and/or lower level in front of the CR window for viewing. depends on your console and monitor arrangements.

I'll do :) When I finish of studing some books I'll take a look to all the designs and ideas of this forum. It seems very intereseting, I'm sure it's full of valuable information!

Ok, thank you. Right now I'm still studing all this but it's nice to know already that I can get a good vox booth in that space! My initial idea was absorbent ceiling and a double slope wall in the south (vertical + horizontal), with bass trap behind the wall. Then yes, some helmotz resontator when we identify a problem. Some quadratic diffusers can be added to the remaining walls too. Something like that :)

Hmm... the hall is there to make a studio with no doors. As you can see in the design there is no doors between any of the work zones, so I hope to get a more affordable insolation using not so good (and expensive) doors. The only weak point: the windows, which I want to be in the order of the same (of not too much below) SNR than the walls. That's added to the idea of creating a place where people can hear and watch the performances, which can be done from the Room 2. The plan is to add a couple of loudspeakers and a couple of sofas, which indeed are nice bass traps. In the hall they can't watch anything. Hmm.. that's not compromising the Room 2 to be a nice quality room, is it? I don't mind if the room has its own sound and it colour the sound from the loudspeakers, there's not gonna be there any critical listening. If anyone thinks its a bad idea, please tell me!

Yes, I have to think that. Not done yet. Thanks! Now I'm thinking in a solution for the double doors. We are going to use them to introduce grand pianos inside the large room. I've read about how to make good DIY doors but nothing about double doors. My idea was to build neoprene frames to fit the doors (like Rod Gervais describes in his book) but that cannot be done with double doors. As you can see in the design now there are 3 double doors (outside, large room & store). The store one hasn't to be so good, so no problem with it. I can get rid of the outside one puting another double going directly from outside to the store, so we can use it only to introduce the piano thru the store. I'll make a simple door when it's the double now to be the main access to the studio, which is the critical insulation point, so that's a lot better. But I have no idea of how get rid of the hall one. I don't want it to be the main door to the large hall because it won't be practical, but I don't want to make a wider hall and loose that space just to put an adjacent single door. I don't want to connect it directly outside too, for the insulation reason. I have another problem too. I didn't think that making a live-dead room in the large one it's going to be very versatile when recording rock-folk groups but very horrible when recording an orchestral or coral band because of the unbalanced acoustic! So I have to think a way to reverse it. Right now I'm thinking in the use of diffusive/absorbent symetrically north & south walls and then a reflective east wall and an absorbent west wall. Then using some kind of hanging panels with hooks to make one or another wall either reflective or absorbent. The problem with this is that I'm not gonna get a good live side, because there is not going to be too much reflections if only one wall is reflective, it has to be at least 2 or 3. So.. any ideas for any of both problems? :D Ah, thanks for your comments gullfo!
one consideration - for the hall - use a glass panel door between the hall and live and CR rooms. this way people can see whats going on... as far as live room treatment - make reversible panels on all the walls so you can modify the space evenly.
