Studio Addition

I am contemplating an addition to my house, which would allow me to have a basement studio. The layout could give me a studio with rehearsal space for my band doubling as a live room. The outer walls will be a poured foundation. I will be shooting for 9-foot ceilings. I did this layout on AutoCAD. Here are some pics. Just hoping I'm on the right track.

Aloha and welcome to the forum, Congrats on your studio build. :D Here are a few thoughts to consider, perhaps. You may want to configure your control room geometry more like this - left/right side walls @ 12 degrees, soffit/speakers @ 30 degrees and rear corner bass traps @ 45 degrees. In addition, an overhead cloud or two will help treat the floor/ceiling reflections as well as some rear wall wall absorption. Hope this helps, Aloha 8)

i would try it this way.

Thanks guys. I'll modify my CAD model and see how it works. Looking forward to viewing it w/Sketchup too. Thanks for the file.

Aloha, Mmm, nice layout, Glenn :D Chuck, either way you choose to go, basically what I was trying to communicate was the orientation of your wall angles from the front of the room to the back. What you want to do is use the side walls to direct the reflection behind you to be absorbed at the rear of the room. Looking forward to your progress. Aloha 8)

Appreciate the input, Kendale. The wall angle thing is still a bit of a mystery to me, even after having looked throughout this site with different shaped control rooms. I've done a bit with room mode calculators and bass traps for my current studio - even figured out what my most troubling frequencies with respect to standing waves were and built Helmholtz resonators to compemsate, but other than minimizing parallel surfaces, I don't know too many of the 'rules.' Thanks for the explanation. Glenn, I sparked up the free version of Sketchup 6. Your model is to scale! Awesome! I assume I can drop geometry into the Sketchup model from CAD. Nice tool.

here's a CAD export.

Thanks Glen. It dropped right into Autocad. :)

I just came into possession of four sheets of 1/2" thick tempered glass that used to be installed in a raquetball court. They are each 96.5" x 52" From what I understand, tempered glass cannot be cut, so I am stuck with the size. Anyway, I am working on my CAD model, incorporating the sheets. Will post pics soon. God, are they heavy! :D I'm thinking of installing them vertically.

Well, folks, this addition is getting closer to reality. I have been interviewing contractors and I am close to gettting quotes. I was hoping to get a 9ft high ceiling, but I won't be able to match foundations if I do (and I don't want to go lower). This being a basement studio and all, if I go higher, the upper floor won't match the rest of the house. Contractors are having an issue with this. As a result, I think I am looking at an 8-foot ceiling. Will this work OK with the rest of the dimensions? Also, what do I need to do with the control room ceiling, contour/trap-wise?
