Building a Box in a box, some questions ...

Hello, :) I am planning the construction of a Recording studio "from zero". I read many sites on the web and of course the dedicates forums on John Sayers... It remains full of small "zones of shadows" in my process, and I would like to have your opinion... So that you understand me well, the construction do not exist already, but I plan in advance at most all the details, and at the moment there are some mysteries for some "Sensitive details"... But roughly, imagine I intend to build a big enough premises with enough ceiling height to build 2 box in the box inside ( 1 Studio & 1 CR ). The framing will be steel or wood I don't now for the moment, and 3 layers of GB 13mm /15 mm /13mm crossed, resilients, high density mineral wool, siliconne, air space, So, the best conditions to do it correctly ... The goal is to obtain a recording studio to manage rock sessions with electric Bass & Acoustic Drums :shot: as well as acoustic instruments& voices.... Plus of course mixing at a "pro" level to make "defs". The environment is rural campaign, but with some neighbours about 10 m at one side ... The premises i plan to make will be of concrete blocks, filled with concrete, in order to obtain sufficient mass and lowered the resonnance frequency of the whole building .... So, Here are my questions, For the Box into the box : Since the framing must be decoupled onto resilient, how do I fix the horizontal part of the framing on the flor, without crossing through the resilient ?? If I must go through the resillient, how can I do the crossing ?? What the trick to avoid "phonic bridges" ?? Because if I simply screw the framing through, the resilient is useless ... Is the framing simply "rest" onto the resillients ? In this case the room can moove ?!!?? For the ceiling now : That the ceiling holds above the walls and comes to stiffen the whole box, OK, but how to buid up walls, since there is no fixations at the top ? In traditional building, the framing is screwed into floor and ceiling ... But certainly NOT for a box within a box where we do not construct till the existing ceilling ( first skin / outside box ) ... I don't plan to use suspended ceiling, but to fix the ceiling frames onto the 4 walls of the box. So, I hope this kind of questions was not already post here, and I well search into the forum ( Not enough ?? )... my apologies if not. I 'll make others posts regarding other questions, in intention to keep each post as clear as possible. Thanks in advance for any answers ... Fabrice from France.

Greetings Fabrice: I can recommend you check out Mr. Rod Gervais, Wonderful Book, Home Recording Studio - Build It Like The Pros. Like I said, it is a wonderful book and is sure to answer many of your questions. It is very well written and illustrated very nicely. Don't build your studio without it!!!! http://www.amazon.com/gp/r.html?R=PM4XS ... pJlHXA8tEA Hope that is some help for you. Stay Gold, Ken

Hi, thank you for the reply, :) concerning this book somebody len me it a few days ago, and I read it "fast across", I think it's a wonderfull book and there is a lot of trick wich help me .... :wink: I'll read again carrefuly this book to check if there is some answers at my questions in there. 8) In case there is not the correct informations for me inside ( i don't think, but ..... ) I let you know ... And everybody is welcome here to tell me their opinions of course, .... Thanks , (and excuse my english, I hope you understand me corectly) :oops: Fabrice,

Your foundation, in anything really, is always the best place to begin. This is an area of high concern but little attention is often given to it. Assuming you are going to use concrete as this floor then I would spend time getting details about wire flow conduit and how, if you have the area and the budget, to have separate slabs of concrete poured for the live room and the control room. It has been used here at johnlsayers and in several books of noted authors, possible Rod included( I have not finished his book), that sand in your block wall cavities will produce better then concrete in the core area. "Since the framing must be decoupled onto resilient, how do I fix the horizontal part of the framing on the flor, without crossing through the resilient ?" The above line suggests you are considering floating a wooden floor, is this correct? Thanks and good luck, Brien

Hello, :)

if you have the area and the budget, to have separate slabs of concrete poured for the live room and the control room.

Yes I plan to do that

It has been used here at johnlsayers and in several books of noted authors, possible Rod included( I have not finished his book), that sand in your block wall cavities will produce better then concrete in the core area.

:? interesting, but I think the sand must be very dry to be effective, suppose I do that, what happens with condensation after ? Humidity can ruin the benefit of sand no ? So, I'm going to make research on that ....

The above line suggests you are considering floating a wooden floor, is this correct?

No, in fact, No wooden floor, only floating concrete ! I explain what I plan to do : Basic Floor of concrete for the entire premise, do by the traditional way. Then, 2 separates floating concrete slabs onto this first floor... as you sugest above Then, lining resilient at the peripheral of each slab, where the framing must take place ... then, building framing onto this resilient, but here is THE QUESTION : How can I fix the frame ??? Thanks for you interest, Fabrice,

What do you think about that ?? Somebody could help me ? Thanks,
