New rehearsal room(recording studio)

Hello everybody.I'm very happy to be part of this.My name is alexander Daiski and I am from Bulgaria. First of all excuse me for my bad english.My first Idea was to make rehearsal room in my basement. But after seeing these good things you've done I'm on the way to do something better. So I;m starting to expalaining: There will be two stages of making my home studio according to the budjet(around 3000 $ for construction) 1.We have to make good sounding "live room" for playing and finish the control room without the stuff(mixer,recorder rack...) 2.We have to add all equipment in the control room(again according to the budjet),but this is second stage,so we don't have to care a lot,except communications between the two rooms(cable channels,electricity,air conditioning...) I live in 4 floor building,but this basement has no direct border with walls of any of the flats in the building.But it,s made from 25 cm. reinforced concrete.So concrete is concrete and we need good insulation. I was thinking to put 5 cm stonewool directly on the concrete/5 cm air gap/5 cm to the internal box construction. This has to be on each walls,floor and top. Also I,m planning to make the door opening outside for more space. The wall between live and control room has to be maybe the same construction,of course with window and door. I don,t like much sliding doors. So in the live room has to be drum set, bass combo,two guitar combos,small piano - fender rhodes and vocals. My qustion is how to threat accousticaly the live room in order to sound good with this equipment.I played in dead room in other studio - it's not sounding bad but i don't feel comfortable there.So maybe i need low reverb room but not dead room. 1.Please, give me advice how to separate the room to achieve best sound performance? 2.If the construction offered from me is ok,what is better heavy or light stone wool?(I can find 150 kg/cub.m.) I will attach the base drawing of the basement with dimensions. I hope not forget something important. Thank all of you in advance All dimensions are in milimeters Alex

Actually this is a Bump! Sorry, but I didn't find something wrong in my post.And no one answer 1 month. Of course I'm sure that is something wrong with me. So please write something. Best regards to everybody.

Alex - why don't you download the "small studio in 3D" file in the stickies and fit it into your space. The control room will fit into your space at the door entrance and the studio in the right section. viewtopic.php?f=1&t=5457

Thanks a lot John for your advice.I'm still wondering isn't it better to use the big part of the room for live room[/b],because we are five people and most of the time we shall use it like rehearsal room.Also we use accoustic drum set witch makes it very loud.So if your answer is - yes it's better to be the large room for live room,please tell me also - with this dimensions(small room) is it really possible to take some accoustic of this room , or try to make it completely dead (especially the walls) and after that using hard surface on top and floor to achieve some reverberation. Thanks a lot once again and cheers! Alex

well - if you use the right area for the control room you will need to walk through the studio to get to the control room (annoying when you are recording and someone barges in) and to have some depth in the control room you'll have to have a door in the front of the control room between the speakers which is not the best option IMO.
