This
a three room facility in Colchester Vermont, USA.
It is being designed by Fran Manzella of FMdesign

Below
shows the first course of action taken in the existing structure.
We added 6" of insulation to the ceiling and added a sandwich
consisting of 5/8" sheetrock - 1/2"Celotex Soundboard - 5/8"
sheetrock to all existing walls.

shows that phase completed in the Live Room

"Plywood
On Isolators" is pretty self explanatory. We used the Kinetics
model K.I.P. isolation system which includes engineered cubes
of densely formed fiberglass atop of which rests a 1/2" layer
of plywood. Forms are put up around the perimiter and a 5"
pad of cement is then poured. When the forms are removed,
each slab is completely independent of the ajoining rooms'
slabs.

This
shot shows the workers as they finished pouring the cement for
the Control Room's floated floor. The cable troughs are plainly
visable.

This
photo is taken from the rear left of the tracking room looking
though the control room of Studio A. It shows shows the floated
slab for Iso 1 (on the left side of the photo), the floated
slab for the tracking room (foreground), and the floated slab
for the control room. The cable troughs in the control room
are clearly visable. The framing in the background is Studio
B's isolation Booth and the lounge.

Due
to its cost, I chose only to float the floors in Control Room
A, the Tracking Room, and Isolation booth 1. We will raise
the floor in Isolation Booth 2 with wood just to get it up
to the same level as the rest of Studio A. New 2"X6" walls
layered with 5/8" sheetrock, 3/4" MDF and another 5/8" sheetrock
will sit atop the new slabs. The rooms' ceilings will sit
atop the new walls, ensuring that the rooms will be structurally
decoupled from the existing building shell. Air conditioning
ductwork will utilize flexible rubber connectors to prevent
any rigid contact between the rooms Studio B and the Video
Editing room will have double wall construction with similar
layers. Their ceilings will be much the same as in Studio
A as well. The only real difference will be in the floor.
They should finish framing the whole space within a couple
of weeks and the sheetrocking should be done by the middle
of January. All the treatments will be custom made on the
premisise, so we're not anticipating moving in until sometime
in April. I'll keep sending photos if you'd like. Thanks for
the interest. This process has been more fun than I imagined
and I'd love to share my experiences with others who are building
their rooms.
Cheers
