Hello! I've been wracking my brain about the best ways to proceed. I've been reading Rod's great studio construction book and online forums to get ideas. My situation is that I'll need a decent amount of sound proofing but I'm on a busy street so there's quite a bit of ambient noise. Of course this will be helpful for me to not bother neighbors but also, random noise may creep into quieter recording scenarios. I do a wide range of things, from jazz to loud punk bands, but the majority is mixing and medium volume practicing. Originally I was hoping to build the studio all the way to the ceiling (currently peaking at 12.5') but I'm realizing that I might run into ventilation issues with the existing roof and also allowing more sound to escape the room if I do that. So I've decided to do the ol' room within a room concept. I live near the beach so there's a fair amount of moisture in the air and I'd like to be mindful of avoiding any mold issues. But the climate is comfortable so dealing with the air ventilation might be something not too terrible to deal with. I had good luck in my last construction attempt (12 years ago). New house, new studio, and hopefully improve on any past successes/ mistakes. Anyway, here are a couple diagrams of what I'm planning on doing. Any suggestions are welcome! I'm excited to jump in, but don't want any bad surprises if I can avoid them. Thanks in advance for any help/advice.
