my studio plans(shed/air-raid shelter)

[pandamonk]

Hi, I've posted a few times about this before, but now I'm actually starting my studio. I've bricked up the doors i wont use in the air-raid shelter and built half the base for the shed. I've had the shed delivered and should have it up by the end of the week. Ok, my air-raid shelter is 3 bricks thick and we'll be putting a mortar skim on the outside, and gypsum board on the inside with 4" rockwool and acoutic foam, and that will be the drum booth. There is a walkway into another part of the air-raid shelter, in which I will put a door (made of a double layer of 18mm MDF). The other part is extremely small and will act as a corridor and as a vocal booth. I will build a corridor (with concrete block) out from the shelter and attatch the shed to it. The shed is 14' x 8' and sill be split with a partition wall with 4" rockwool on both sides. The outside of the shed will have a mortar skim to seal cracks and add mass. The whole of the inside and outside of the shed will be covered with 4" rockwool (with material covering the inside). I will then build an outer shed (with all cracks/gaps caulked).
None of my design is definite yet, so please advise me on how to make it better and point out my mistakes(if i have any).
Thanks a bunch guys

I would definitely recommend that you consider not splitting up the shed into 2 rooms but make it a 1-room versatile studio. That control room is way too small to give you a decent mixing environment (take it from experience - MINE!!). If I were in your shoes, I would build a simple slanted wall that goes from the left side of the shed at max width and slant it so that it meets the right wall about a foot below/above the horizontal walls. That should be enough to cut down sidewall reflections and still leave a usable space. Your mix position would be at the far right end of the shed and would leave the open space behind you for tracking if needed. You could also flip it around and install a sliding glass door between the vocal booth/hall and the studio so you can look in, but then you have to walk around your console/mix gear to get around in the main room.

There are probably other solutions as well but that would be about the simplest way to get something that you won't feel like you wasted your time and money on 6 months from now.

Good luck,
Darryl.....

Will i get sidewall reflections if the whole wall is covered in rockwool? Wont that make the room completely, or relatively, dead? Im not bothered about not seeing into other rooms, so don't need the sliding glass door(good idea though). I want to split the shed, as i will need a live room for recording other instruments(guitar etc), and for possible band practices(with an electric drum kit so can turn the volume down). The shed is 14' x 8' so i was thinking of have an 8' x 8' live room and a 6' x 8' control room. It does not need to be perfect, as its just an amature(ish) studio in my back garden.
