AR Small CNTRL RM-> ideal dimentions/ -->New Design(s)!

I wonder if the sprinkler is becoming too much of a focus point? I wonder this because, I cannot say with any authority, how these pipes can or can not interact in this situation. What I mean is, have you asked the locals what they expect from you in this situation? Is there a possibility that walls can be developed below the sprinkler(s) and not have to be encased in the wall? If you can get a ten foot wall height and still be below the pipes, then you may have more flexibility. But you have to ask that question to your local authorities. Hope that is of some help.

From what I understand you can't build a wall within 4" of a sprinkler other info i read says you can't stack anything under a sprinkler if the space remaining is less then 18" I think it's best to keep clear. the sprinkler pipes are 9 1/2 feet off the floor and because the ceiling height is variable this leaves about 1/2' to 2' above them. besides constructing a ceiling in all three rooms (under the sprinkler heads and against code) I don't see a way to go around them and still maintain separation between the three rooms. I think we're going with design 5B we're having a meeting with the builder tomorrow, and I am eager to move on and try to get this project done before Christmas! :yahoo: I would still like to hear any opinions about these particular dimensions/angles for the control room before we start setting studs. ...let me know if I'm overlooking something. -best mates

Not Internet expert advice:) What is code in your hometown? I wouldn't have much interest in helping in a situation where the eyes are closed to safety. Especially an overhead sprinkler ;) But thats just me

ok I just spoke with a (assistant) chief over at the Brooklyn Department of buildings He said that covering up a sprinkler head would not be a problem as long as the remaining area is covered by the spray radius of the adjacent sprinklers. He also said that if I were to build a wall NEXT to a sprinkler head the required space for clearance was 4" there are 8 sprinkler heads in our room each set in a 18" from the outside walls. each head has a spray radius of 7ft. This is good news! meaning we could remove (or block) either of the 2 center pipes to build the Control room and still have the (aprox.) coverage we need without having to call in a master plumber and go through the large process of relocating a sprinkler vien, or costraining our design to clear the sprinkler heads. so the direction of this thread can now get back to the original topic: what are the ideal dimensions for this control room? the given we have is that the length from the front wall to the back can not be larger than 12ft. Dropping the ceiling is no problem, and I would actually like to angle the ceiling to be considering its construction in the future within the new room. I'm mostly looking for suggestions or equations that would specify the type of width would be ideal (acoustically) with the given restraints. whew, feeling safer already!

You asked for it... room+ratios

copy... thanks for the help, I'm still interested to know how a trapezoid shaped rooms with splayed walls fit into these ratios Are you suggesting to go with a rectangular shape for the CR?

No sir, actually I wasn't suggesting. I had to look back over the thread and I see you have picked out a set of ratios that you are already working with. :) As has already been commented on, a control room needs balance/ symmetry for no other real reason then the fact that you have two ears. If this is modified, in relation to your two ears, early reflections and even direct reflections could cause mixing errors based on what you think you are hearing. I wouldn't say "don't do that" but I would say, educate yourself on the whys and wherefores in respect to having a trapezoidal control room. Now an isosceles trapezoid...that's worth looking into.

whew, feeling safer already!

Aren't you glad you came here, to get good advice? :)

Why are you angling the walls? This may help understand my question. Andre

ok guys we were able to tape out the locations of the control room walls in the space this weekend: Not as pretty as in on the computer, but we made it work. our final dimensions for the room: W: 6'10" (front), 9' 8" (rear) L: 11'11" H: TBD the walls angle at 8deg Structurally I've been trying to keep it as symmetrical as possible, but with that front wall it's a little tough. Symmetry was also sacrificed to get the door to work into the room on the left. we had to move it away from the wall a bit, and in doing so had to shrink down the window on that side. There was a concern with visibility in reguards to the window positioning especially into the room room to the right, which will be the main tracking room. by placing the 3x4' window as close to center as possible on the right wall, I think this has been solved, with a clear line of sight from almost anywhere in the CR to the next room. eventually i'd like to build in a soft soffit enclosure for the entire front wall like so: 3'6" up and then 10deg downward slant. it's tricky figuring out how to include a secondary set of speakers I'm trying to keep this all in mind in this design you can check out the sketchup file here: -still trying to figure out what to do for the ceiling height. any thoughts?

UPDATE: the sketchup file was too big to attach: :cry: here is an outside link to download: http://www.djbakedpotato.com/sketch/AR_CR2.skp
