I must stress that I have a small budget and space, and this room must accomodate drums, bass, guitarist, and leak as little sound as I can get away with (it's 80 feet from my house, with nearest neighbours about 50 feet away)
The room when finished will be approx 13' long x 11' wide with a peaked ceiling (lengthways)
This will be 6'6" high at the sides (long walls) and about 7' in the centre.
I have a maximum of 14' x 12' to work with(not an inch more) with six inch thick staggered stud walls. I can't build out of those dimensions and building inwards would eat up precious room space.
The attached not-quite-to-scale pic gives an idea of whats what. The top and left walls are staggered stud on 6" base, with a double fire door entrance. The right and bottom walls are single stud next to the existing concrete slabs. The pipey things top right and bottom left is ventilation, ducted through the walls (the black lines represent flat channel with a couple of bends from entry point to exit).
Walls will be 18mm MDF mostly, with drywall inside the room itself.
Ceiling is a tricky one, it will be 6x2 cls timber on top of the stud walls, not touching existing structure and will have lots of mass fitted up between and onto the bottom of the joists, upto 60mm (2 mdf and 2 drywall). The beams will be angled in the middle, for strength and to follow the shape of the existing roof, which is crappy asbestos sheet. (Yeh, I know
)I intend to put solid 2' wide rockwool traps in every corner, and probably a couple of panels on the ceiling, and a couple on walls.
With the previous info...
Is it worth me building angled walls, or changing the room shape in any way?
or
Shall I stick with my plan and worry about treating the rectangle I'll end up with after it's built?
Many more questions to follow but for now I need to know I'm on the right track...
