1 car garage studio design: need help with door

Hello John and others, Please refer to my newly created studio construction thread: http://www.johnlsayers.com/phpBB2/viewtopic.php?t=9166 I need ideas for the studio door and the room. The existing door to the house is deep in the corner where the slab begins. It appears I will not be able to build right up against the wall there (and share a door jamb) due to multiple drywall layers... I need ideas on how to deal with it. The room will be used primarily for tracking drums. I want to be able to get a great drum sound. As such, I need to maximize the space. I understand I need to deal with the parallel walls as well. Sketchup file included is current (as-built?) and drawn to scale. Thanks for your help!

More details: -detached house -attached garage -neighbors on one side only -no living space above garage (attic) I plan to add 2 layers of drywall to existing interior garage walls and ceiling (green glue in between at 50% coverage) for a total of 3 layers. Studio will be a true 'room within a room' structure built on concrete slab, with 3 or 4 layers of drywall on interior of studio room.

I was hoping my *ahem* donation would spur activity on this thread. 8) I understand it's a small space to begin with...

I think in this case, the best place for this question is the construction forum and maybe post a sketch of what your wall construction around the door looks like and then I'd suspect Rod or Knightfly can weigh in on what may be your best course of action...

Try This... I'll explain what I did & Why in a bit in more detail... Gotta Go! The short of it its, you have French Drains around the perimeter of the space, with obvious moisture problems. You don't want to build on top of that system and you'll need to ad a vapor barrier at you new construction. The layer of joist is all PT, the sheathing, then VB, then your floor construction, bring the new height of the floor up to the same level as the door.

I certainly appreciate the input. You might be misunderstanding my drawing- those aren't french drains, they are gaps between the newly poured slab and the outer garage foundation walls. Deliberately placed for structural isolation.

Yes, I did misunderstand your design problem.. So as I re-read your problem, basically your door is not going to line up with the inner leaf wall of the new room? Move the door... don't let the tail wag the dog.

There's a powder room right next to the door- so the door can't move, unfortunately. Guess I'll just have to come in a little bit and at an angle. Not too many choices here I guess.
