Floating floor or not??

Hi everybody! I have fallen in love with this forum, what a great piece of info...! Thanks John & everybody else for all your endless input! I have a question: I want to build a recording booth in my appartment. It will look a bit like John's design for a vocal booth. I was planning to make it a box in box construction, for obvious reasons. My appartment is a completely new building and everything is made of concrete. I have been reading a lot about building studio's, but it seems there are different thoughts about floating floors. I want to float the floor of the booth, because I would think that would add to (or better; be obligatory for) the box in box construction. But then I read Rod Gervais great book on building home studio's and I get confused! I think I read in his book that he's not a big fan of floating the floor other than with a separate concrete floating floor. But please correct me if I'm wrong. That would ofcourse be way to heavy in a flat... Do you have any suggestions? I'd like to do it right...;-) Thanks in advance!! Leo

Where is your apartment? If it is on the ground then you already have a good start...and if you are on an elevated level then you may want to skip the floor as floated and look into a simple decoupling of the floor.

I feel a bit stupid now... I always thought that decoupling the floor meant the same as floating the floor. I'm dutch, so there you go hahaha! I was actually thinking of decoupling then....:-/ Thanks very much for your reply! I feel enlightened...;-)

Ow ps, I'm on the fourth floor...

An elevated audio environment is a difficult thing to build. A floated floor is most likely more than you can afford and maybe more than the structure can support. A decoupled floor is a different thing.
