I am certainly nowhere near building anything on that scale...the way you have floated the cement floor is beyond belief!
:) I can tell ya that learning how to do it, and then designing it, caused the death of far more brain cells than actually building it.
The only hard bit was pouring the concrete. You have to be FIT to shovel 6 tons of concrete around. And I am NOT FIT :)
The worst was pouring the first supporting slab of concrete. I'd never laid a concrete slab before, and while screeding it flat I crouched down, and soaked my a55 with wet concrete for 2 hours. I later discovered the concrete ( strong alkali ) had burnt the skin of a 6" diameter area on my a55. it fvcking hurt for weeks!! I've still got a bad scar :frown: :)
My needs are much more modest, and will be in a basement, so I am not worried about outside sounds or isolating to the outside world, but I just want a comfortable environment to track and mix, and get myself separated from the live room.
Well, if you have modest Isoaltion needs, and the main gaol is isolation between the two rooms....
First investigate if the original floor can be disc cut to decouple the rooms without causing structural problems/distasters. If it doesn't, then do it. It won't cost much, but is VERY DUSTY.
Then whether you disc cut or not, you should build your inner rooms with the biggest air gaop you can afford between the rooms, and use as many layers of drywall on your walls and if possibel ceiling as you can afford.
Floating the floor will lose you room height anyway. And to do it to any degree of success will cost you a LOT of money.
