New Room Advise

[Gregwor]

I'm not entirely following what's going on there, but it seems you understand the concepts here. Keep showing pics of progress (so you can be stopped if you make a critical error). I hope this all works out awesome for you!

I'll try to post some new sketch up stuff and see what you guys think. I just have to really sit down and work at it for a while.

Been awhile but getting somewhere

I will try really hard and do a sketch up soon.

[Gregwor]

Awesome!!!!

[SunkenCity]

here are some basic drawings of what I'm thinking.

I need to figure out who to consult about the steel support frame and design. I'm hoping 1" square stock will be strong enough to support the loft structure.

Figured I'd bounce it off you guys. It's not a precise drawing just the gist. Still wondering how to figure out how big the air gaps should be and how to figure for the steel frame taking up some of that.

The second image won't work well whatsoever.

If you don't require much isolation in the live room, you could ditch building that inner leaf in it.

Glad to see you're working out the bugs!

Specifically what wont work?

I'm trying to get a decent amount of isolation from the rest of the building and really good isolation from the live room to the control. It seems like majority of the sound transfer is coming from the shared concrete wall and structurally.

Well I started to get the hang of sketch up after really forcing myself to figure it out. Just getting the basic idea so far hopefully sketching it out will help to illustrate what needs to be changed.

Sorry, I didn't see your reply on July 4th! I would've answered had I seen it.

Okay, good work with SketchUp! Are you using Make now?

Basically, just remove the steel frame work and your plan should work. Please change that in your SketchUp (you should have each part of your SketchUp in a layer so you can just unselect the layer and it should disappear) and repost some pictures so we can see and confirm that it is good.

This is far from correct dimensions, but here is how your walls should be.

Your concrete room will be your outer leaf. All of the other rooms are literally their own rooms within that outer leaf, not touching each other or anything anywhere other than the floor.

I just saw that only one of your walls is concrete and the other 3 are wooden. So, I just changed the color of the 3 exterior walls to represent that. Here:

Yeah make does work alot better.

I really really really want to keep the loft space for a number of reasons. The steel frame is to support the loft which will be its own decoupled room with one side open to the live room. Really trying to figure out how to make it work.

Totally understand your drawing and mine will be the same as that so the live room gets its own inner leaf. Do you make the baseboards like that or do you cut out for the door frames?

Tricky for sure. So, basically the loft will be a part of the live room? Or will it be a lounge area with a window looking into the live room?

You mean the sill plates? For maximum isolation, you would leave them and put a door seal on it just like the rest of the door perimeter. Ideally, you would have 2 or more seals around the sides and top of the door and a single one on the bottom with an automatic door bottom installed on the door to be the second and/or third seal for the bottom. You could maybe get away with just the automatic door bottom, but the seals around the doors are always the weakest link in the isolation of a room, so the more, the better.

yes the loft will be part of the live room. Having that space up there makes the room feel alot bigger and more interesting. When I first got the room there was a drywall partition covering the opening and the room felt tiny. Its a good spot to store stuff and hang out looking over the live room wanna throw my futon up there. The added live room volume is nice too.

can you post some pictures of what your talking about with the door and frame? is the the door frame part of the the baseboard for the studs or is it shimmed in?

Is there a good way of doing a single door with good isolation? I seems like alot of bigger studios only have single doors.

Here is a thread that shows everything you'll want to know regarding doors:
Studio Door

The only things i can see on this door that you will probably do different are:

- Don't use glass unless you're desperate because it is super expensive, makes the door harder to build, and did I mention it's super expensive yet?

- Don't use through door handles/plungers. This one in particular was for an outside entry door so security was needed via the through door handle.

It seems like alot of bigger studios only have single doors.

First off, big pro studios have two doors. They are typically situated around sound locks. At home studios, we don't really have the luxury of sound locks as space is at a premium. Therefore, at home studios, we have our doors back to back, not across a large sound lock area.

Is there a good way of doing a single door with good isolation?

Good isn't a specific value. Basically, a single door can perform like a single leaf wall. You will be relying entirely on mass law and 3 good seals. Basically, I'd say no, you can't get "good" isolation with a single door unless it's made of lead.

Build your door out of HDF layers, don't use through door handles, use commercial door closers, use a good set of seals like the 4731, use an automatic door bottom, and use good hinges. Regarding the 4731 and hinges, I've personally posted in the construction materials threads about availability of the 4731 and cheaper alternatives to the expensive hinges. I hope that helps.
