Thanks for the tips.
There is a BG dealer who has a room setup for HT. I'm going to check it out and see how well it works in his place. Otherwise it looks like some sort of SEOS build for me, in addition to a could of DIY subs.
Right now my leading candidate for a projector is the JVC RS4910, since it has good light output and lens memory.
The media closet is where all the heat is generated. I plan on installing some sort of exhaust fan in there, probably at least a 110 CFM bathroom fan - one of the 0.3 sone Panasonics might do the trick.
The biggest issue with ventilation is how to get enough cool air into the space. Our summers here get up to 110F. I plan on building a couple of dead air vents to exchange the air with the adjacent room.
As for building codes, I'm pretty sure we'll be ok. The project will be added to our current permit. We'll be building a separate garage.
Yes, we've already run wire for ATMOS. I'm waiting to install the speakers though. Honestly a 5.1 setup is what I've been using and I'm perfectly happy with that.
My biggest worry is isolation for bass. BassThatHz built this over-the-top HT with all sorts of sound proofing including double staggered stud walls, and still got relatively high spl's 50 ft away from his place. Of course he has a zillion subwoofers
It wasn't until he tore off the outer skin of his building and reinforced with multiple layers of OSB that he got the bass control down to an acceptable level. Being that the exterior of the house is already finished, I'm really hoping to not have to go that route as it would be just too expensive at this point.
I'm willing to spend money on this project but I'm limited because of all the stuff I have to do with the rest of the remodel. If push comes to shove I'll just finish it off to the first layer of sheetrock (required by code) and as more funds become available, I'll do the rest of the finishing.

Honestly, the BGs are good speakers but I do not think they will achieve the SPLs you will need in a decent sized HT. I just don't think they can be driven hard enough to achieve the dynamics a good HT will require. It sounds like you are willing to spend the money to do it right....don't skimp on the audio side.
A 140-150 inch anamorphic screen requires a bright projector. What are you planning to use?
I'm glad to hear you aren't planning on skimping on soundproofing...it is expensive to do it right...but totally worth it!
Make sure you have good air exchange - lots of movement/exchange as equipment + people will generate a LOT of heat.
You should also make sure it isn't against code in your town/neighborhood/covenant/HoA rules to enclose/finish a garage. It may be a problem.
Interior doors - solid core/wood, sweep and threshold/seals will do the trick....
As far as ATMOS goes, it is just barely announced for home use...minimum of 7.2.4 though it can go far higher. I would worry less about that at this point and just make sure you run conduit/wiring for future expansion.
Don't get lost in trying to see the forest for the trees. It is easy to get overwhelmed in trying to visualize a finish space that is as complicated as a fully decked out HT can be...
