Oh op l do feel for you..YANBU to want a calm environment for your Dcs.
As they get older it will benefit them hugely to have a calm orderred home life rather than a panicked one, especially when they start school.
It does sound like you are miles apart, my Dh and l sufferred hugely when we first married as l don't drink much, need 7 hours unbroken sleep and like a peaceful house.
He was a supper stressed workaholic who went to bed at 2am slept fitfully for a couple of hours, got up, came back and generally was very disruptive, he also liked loud rock music on at a deafening volume!
4 months in l fell asleep at the wheel of my car , in rush hour and almost drove off the hard shoulder into a ditch....it was the wake up call l needed, l could have killed someone or myself.
Since we have had seperate bedrooms for whenever l need to sleep undisturbed, weekends are together, some weeknights we start together but as soon as there is any disruption l am off to the other room.
It has saved our marriage. ( 15 yrs)
if you have the space insist on it, if not make a comfortable bed corner somewhere that will be quiet ( corner of lounge perhaps)
The other things would be intolerable to me, it would be a case of get organised or leave l am afraid as l simply couldn't live in chaos and nor should any child, what about when they need quiet study space..
He needs to understand it is not neccessary to shout, he can come and find you if he needs to speak to you, it is bloody rude too.
Good for you finding the peace we all want!
