We are buying a new home in the next few months. Being an architect/builder it will likely be something that will get completely renovated. Part of the plan will be to have an outbuilding that will house my workshop on the first floor and a music room and exercise/yoga room on the second floor (for the wife). My music rooms have always been the extra bedroom, or the basement, etc... This will be my first dedicated music room, and since it's being built from scratch it is completely sculptable at this point. In terms of playing, I am really just a hobbyist. I don't have a lot of experience recording, but do play guitar, banjo, mando and pedal steel...so I do want to have some mics setup and ready to go for acoustic and electric recording. This space should also be large enough for a few people to jam/record. As of right now, I have it designed as a 12'x12' room with an 8' ceiling. The walls and floors will be birch veneer plywood. No windows, but probably a large atrium type skylight in the ceiling for natural light. The walls will be spray in insulation to try and make it quiet. Any thoughts on ideal size, shape or materials? Next, I need to outfit it with some recording gear...and have no idea where to even begin. My plan is to get a computer/software, some mics, and a couple monitors. It would be great if the monitirs could also double as a PA for jamming in that space. Where to begin?
