I know there are other threads under construction that covers this, but here it goes.
The first room which is almost excavated is going to be 10' x 10' x 8' high, contain most of the air systems, toilet, and air lock entrance door. I've installed the outside 4" air intake pipe made of steel sched 40 galv. about 5ft above the ground with a brass wool filter and cover. It goes down to a "t" which which has a 12" nipple on the bottom that will act as a particle trap, then the 90 goes to a 4" steel knife valve. This in turn will feed into a bio filter, a merv 13 particle and carbon filter and a UV light. This is similar to the one I presently have for the house, not quite as powerful, less CFM. Then to a 4" ABS pipe sweep that will contain the CO2 scrubber, the in-line fan and on to the large hand cranked blower.
This system can be sealed from the outside via the knife valve, and the inside air can be cycled thru the Sofnolime and carbon scrubber filter either by the in-line AC fan or the hand blower. I also have (2) 300cf 3000psi air cylinders to provide positive pressure for about 18 hrs
14psi., and a small O2 bottle to replenish the oxygen while using the scrubber.
I have the (4) t-105 batteries and the 4000w inverter ready to be installed as soon as I'm ready, the system will receive 24VDC from the house system to keep the batteries charged. I can turn the genset on/off from a remote switch on the inverter from inside the shelter. These will be in a sealed room that can be vented to the outside to remove any hydrogen produced during battery charging, either from the house or the genset.
The toilet is a manual flush up design that will receive water from my outside tanks and send waste to my septic system.
Twist 'n' Lock Manual Toilets
The inner door is from a bunker set up during the late 60s, very heavy, 4" thick, and will be mounted in a 1' thick wall, then filled with lightweight concrete. An entrance will be a 4' x4' room outside the door, with a shower system, deterrent devices and a sump pump to carry off waste water. I built a similar system at my last underground shelter.
I've researched the LED grow-light systems for interior plant growing, Naekid had some great ideas using fiber-optics to bring in natural light, still looking into that, the growing of plants will help reduce stress if we have to stay for extended period of time. One wall will have a large mural of a outside forest scene theme to also help, looked into this when we contemplated building a underground/earth sheltered home.

Cooking will be done on a butane fired stove that
uses cartridges, and has the least amount of pollution, it will be placed under or near the exhaust pipe similar to the intake one, which will also have a knife valve that can be sealed. Water will be gravity piped in from my 5000gal tanks from above ground to 55 gallon barrels, thus having a reserve supply if above ground tanks are disabled.
We have an abundant supply of long-term stored food and goods, these will be in-place as soon as I am done.
I have an extra CCTV system that is also ready to install, one wireless the other hardwired, both have external mics. Ham radio gear will be installed also for communication.
Believe it or not I have about 90% of the equipment all ready to install.
Well you got me started....
