Steel support frame for a freestanding loft

[ClaytonBarton]

Hello everyone,
I'm trying to design and build a steel support frame for a freestanding loft of sorts. I'm in the process of building a recording studio with acoustically isolated rooms within a big room. This requires freestanding structures decoupled from everything but the floor. Normally you just build a room within a room not touching anything but the floor but the complications with this are I want to keep the above loft space above the two smaller rooms. This requires that the loft area be supported by separate structure is instead of the rooms below. I was thinking a steel frame structure could go in between the inner leaf structures and the outer leaf(existing room).

Below is how the room was when I got it.

This is a shot from above of 2x4 frames that with make up inner leaf walls and outer leaf existing structure with the steel frame in between.

this is the basic frame design in small section to be able to be moved thru doors then bolted together.

And this is a cross section from the side.

Nothing really to scale on these paint images I just didnt want to 3d em before knowing what I was building. I need the figure out how much weight I could put on frames like these made out of steel square tubing. Anyone know about this kind of stuff?

From a noise/vibration standpoint, consider using wood instead of steel, wood will damp transmitted vibrations much better than steel.

Yes, I'm afraid so. As mentioned, you need to have an engineer or architect help with the design, and you will need to get permits to build it and have it inspected according to your local Building Department.

Sounds like a fun project -- good luck!
