They just don’t understand! My theater build journey: an exercise in DIY

While I’m sure most people can appreciate the use of a dedicated theater space, they just don’t seem to understand my excitement for, and the purpose of, a full-on dedicated theater build! That’s why I’m grateful for a community like AVS. Not only has AVS been a place for me to go and get ideas to fuel my theater dreams, it’s a place where I can share my passion with others like me. I hope you all enjoy my build journey as much as me.

Quick background. We moved three years ago, found the perfect house. Except for the theater space, less than ideal:




No shortage of obstacles here, the least of which is the size. Raw dimensions are 19’9” x 12’8” x 7’10” not including the small bump out. It’s all I have, so I’ll have to make the best of it.

My first step was to get into contact with Shawn Byrne. While I plan to DIY everything possible for this build, some efforts are best left to professionals. A full theater plan was set forth! I think my goals for the space are realistic. 6 maybe 7 reclining seats. A/T screen, stage, riser, DDGG, walls isolated with ib3, clip and channel for the ceiling. 7.2 with Atmos, projector hush box, full acoustic treatment, communicating doors, etc,etc,etc-all the usual suspects for around here! We can get into the details as we progress through the build. I know others have posted they’re plans with permission, I’ll see if I can’t do the same. I do have a crude drawing of the space:



I am one of those that believes if it’s worth doing, it’s worth overdoing! So that’s what I plan to do. I don’t like to take shortcuts and I don’t like what-if’s. I will focus on building out the room as best as the plan and my budget allow. The focus will be the room first and then the rest. I have an idea where I’ll go with equipment-I’ve always wanted separates. I probably won’t reinvent the wheel with color or design. Those things will be hashed out when necessary.

I have been inspired by so many that have come before me on AVS. I plan to share as many pictures and explanations as I can in the hopes that I can pay-it-forward. Sappy, I know.

Up next. The pre-build build.

I know this subject has come up at least 100 times before, but I can’t seem to find the right thread. If anyone can help me to properly embed these photos it would be greatly appreciated. I’m using an iPad if that matters. I hope that my building skills are better than my computer skills!

if it is any consolation I've never figured out how to embed pictures with my Ipad, just my PC

I’m hoping there’s a way, seeing that I don’t have a pc. I got a little closer, little grey boxes. Progress....I guess
Update for anyone who’s interested, finally figured out how to embed the pics. Let’s just say I should stick to my day job. Now if I could only get the site to not load the pictures upside down

Is there any rhyme or reason to the site loading pictures upside down, or is it just me? An I pad is my only available option- and I’m trying to update my thread but I won’t with upside down pictures. Arggggh!

No engineer for this one- beam and poles was only needed to carry seven long span floor joists. During the restructure, I’ll add seven full length 2x10 and two load bearing perimeter walls. This will shrink the span on those and the remaining floor joists to just under thirteen feet. That’s no problem for a 2x10’ and the same span already exists for other areas of the house. I’ll add some bridging just to stiffen it up a bit.

It’s a light beam and cuts easily with a reciprocating saw!

Might be the first theater I've seen that gains some height by giving up some width.

Are there any load bearing walls directly over where that beam is coming out? Like walls holding up a second story?

Not to worry BIG, the beam was only carrying floor load. There’s only a single story room above- family room- and all other walls are carried by the perimeter foundation. This is the room above the theater

The subject of structure can sure raise the alerts- I’m pretty sure we’re safe , at least that’s what I keep telling my wife!

The real question is why didn't the builder simply just sister multiple floor joists,
skip the steel beam/support post/concrete pads?

It would be cheaper for them, and would give buyers a better basement.

Just an unrelated question are there any bigger windows or a door leading out of the basement? if not that would not be a code legal project in my county. Here finishing any basement space requires an emergency exit somewhere in the basement. If you build a bedroom it has to have the exit in the bedroom but it can serve the entire basement, unless you have multiple bedrooms.

That same code applies here. Any finished basement space requires egress somewhere in the basement. And each bedroom?, requires egress- pretty sure. At any rate, to answer your question, I currently only have one means of access to the basement, with no plans to be code compliant!. I will build to code, that’s to say that my construction should pass code if it were to be inspected- it will not be

I fully understand your position and have worked on projects in similar basements. Just be aware that when it comes time to sell your house an astute inspector may point out the fact that your basement is not legal and hold up the sale. You may want to bite the $3-5000 bullet now.

The vast majority of homes in my area-western New York-do not have egress from the basement. Doesn’t make it right, but ends up not being a huge deal for home inspections, or sales. I’ll just have to take my chances

I would really love to update this thread with progress pictures from the work that I’ve done so far. Unfortunately, all my pics are loading upside down. Even pictures that I’ve already uploaded and posted. I’m open to any suggestions, tips?, etc

Who knows? I wouldn’t have built it this way, but I’ll make it work. I could show you what I’ve done, if I get ever get my pics to load

I'm seeing the pictures perfectly well (and properly oriented).
I use http://tinypic.com/. I'm not crazy about it, but it's free, and, as long as your browser has an ad blocker, not too annoying.

The “pre-work”

when Got the go ahead from my wife, I wasted no time- cleaned out the space, took pictures, measurements. Got a set of plans from Shawn Byrne thanks to the AVS/ erskine member deal. And then.....nothing. Too many other projects to get done. That was two years ago. I finally got to do some theater work last June. I was putting in a firepit for a new patio and had to run a gas line


The utilities that run down the middle of the theater ceiling need to be moved anyway


gas, water, electric- perfect chance to do some theater work-kind of. The water and gas lines got tucked up on top of the foundation on either side of the room-guaranteed to not be in the way.


You can see the line that goes out to the patio on the left. I quite enjoy cutting and threading pipe. Really satisfies my OCD. Here’s where it comes outside


Another section.


Sorry, no pics of the water line above the sill, covered it up too quick I guess. It’s hiding behind the grey conduit. Gotta love PEX
The electrical conduit would prove to be more of a problem. I figured the easiest thing to do would be to get it as high and as far to the outside of the room as possible. I didn’t want to have to box, or soffit around it. I wanted it outside the room. Should be ok where it is.




There’s no splice in the wire-it’s one piece from the house panel to the shop sub panel-about three hundred feet, luckily I could pull it from the conduit to this point


There’s an el/body right where it exits the building. now, just Move the conduit- and fish the wire back to the panel. BUT....first I need to build a wall

this will be the load bearing wall that will carry my sistered floor joists so I can remove the beam. This wall is the “outer” theater room wall, it will have the outer entry door.

These penetrations need a little clean up, they were sticking way out- I tucked em in as far as I could


Much better

I still need to deal with an HVAC run, and the dreaded sump pump. I wouldn’t get back to work on the theater for nine months

That room will be plenty big. Looks great! You can use your A/V closet as a perfect infinite baffle subwoofer closet as well. Should be awesome!

You are correct. They are not pressure treated. The bottom plate of that wall is isolated from the concrete with sill sealer, as will the rest of the walls. The stud on the left, next to the foundation has since been removed for foam board insulation installation. There will be no direct wood to concrete contact.

Inexpensive sill gaskets are the way to go. Cheap and no poisons introduced to the home via pressure treated lumber.
