I love this stuff tooI love having somebody to discuss this with. If you are so inclined, I'd like to keep talking here.
It's always cool too see how people go about things differently.
Actually, we are in similar situations, my studio is primarily for myself , my label and publishing. But I hope to gain a second career as time goes by. I'm a full-time parent of two, so being at home goes well with the home project studio goal.
I think it's great that you have enough room to consider options. My basement space was very limited because it's an old house with what used to be a crawl space. Good for band practice though, no noise issues with neighbors with 1.5 acres and underground.
I had to get concrete bucketed in and take another foot of dirt out of what is now my main studio room. All this was necessary for the renovation anyhow, but the basement space dictated no major construction -- ceilings just too low. I figure I can record in other rooms of my house as well.
I will be building a family home theatre room addition that could double as a cool live room (it will have a vaulted ceiling (18ft or so) and floor space about 25x20). For now I just want to finish "my project experiment studio" and get up and running by this year's end. I could also build something bigger on my property if it leads me there. I have a cool old barn that would make a killer space.
I'm interested in all music, but will probably be recording rock/jazz and rhythm section stuff. My main room one-room approach incorporates a drum and vocal gobo, with adjustable 6'703 panels on the wall. I can't wait to try it out...finding time to finish the construction is my biggest challenge now
I'm a drummer mostly, and I have also recorded in a variety of places from small style studios to a larger ausberger designed studio --working on independent records. Home recording is really a great option now. I am fascinated with live room recording with no headphones, foldback through studio monitors if necessary at all. I am hoping my limitations will be my strength.
Since you have the family room, sounds like taking advantage of the space you gain by losing that door would allow for a well-treated rear wall and nice sounding control room. You might even have room for a surround setup in the control room?
