Gimmepilotwings build thread
I am in the planning stage of my theater build/basement finishing. The house is being built and I have roughly 4-8 weeks before I can move in and start work. I have a finite budget for the entire basement. I would like to save as much as I can towards the actual home theater portion. It is about 1200 sqft. It is completely unfinished. There is some insulation on the outside walls, I assume due to code in Colorado.
Some pictures include a plot plan that includes some dimensions, a floor plan that can be modified. None of the walls are built except for the utility closet. There are also some pics of the place and a video I can share if requested.
1. There must be one bedroom downstairs. I have planned this for the NW corner of the basement. This is not moving, but the size of it can.
2. There must be one bathroom as well. The plumbing is already in place, and I do not want to do move it due to the expenses involved.
I would like to soundproof the home theater as much as possible. Where I want to place the theater will have 3 concrete walls and an open area currently that is open to the rest of the basement. I have not determined the exact size of the home theater, but it will be placed in the SW corner of the basement. That corner is ideal in the fact that it has no windows, three sides that are concrete walls, and is located beneath a guest bedroom that will not be used very often. I would like to keep the sound from traveling upstairs as much as I can. It isn't a big concern if sound travels from outside of the home theater, and into the rest of the basement. With that said, I will be likely be installing clips, DD, GG across the entire ceiling to help with this.
I will try to do some of the work myself to cut cost. (Some framing, insulation, running cables etc. while leaving things like HVAC, plumbing, and electrical connections to the experts)
The ceilings are 9' tall across the entire basement. However, there are metal I-joists placed in various places across the basement for load bearing about 12-14' below that 9 feet level. Trying to decide if I am going to lose that space and lower the ceilings to around 8' or if there is a way to work around it.
I was going to ask a lot of these questions in the soundproofing thread, but I wanted to start my own theater thread first...
Do I need to do much soundproofing on the rest of the basement that will not be the home theater? Flanking is a concern. Only really worried about sound traveling upstairs. Do I need to use backer boxes across the entire basement, or only in the theater portion?
I haven't pulled up the insulation that is currently attached to the concrete walls to see if there is a gap in between, or if it is attached directly to the concrete. If it is attached, do I need to yank it out everywhere to leave a 1/2" gap? Should I only yank it out in the theater?
There is a sump pump in the SW corner of the basement where I would like to place the theater. Should I move the screen forward? How do I soundproof that? Do I even need to, since it is in the concrete slab and we should only hear sound from it if the basement floods?
There is also a set of pipes for a radon mitigation system. Should I insulate around it and build a soffit?
I will have a ton of questions about different equipment to purchase, where to place the AV gear, etc. but thought I would get started here.
Any kind of help that anyone could provide would be greatly appreciated.
