Noise and mess OP! All parents get that indeed.
Does your DH work from home? Can you get him a garden office or something like this?
Can he have a retreat in your room where he can chill? After he has given you a hand with cooking/ feeding, clubs, homework and laundry, of course.
He now sounds like your DH is over reacting. But you mentioned your son is so rude to him. That is not good. Neither that your husband does get annoyed or tell them off for doing crafts. At least they are destroying the house.
As parents, we all get too much of it now and then, and a break is good, but he should have not left you like this and dump it all on you either.
I think your husband needs to start addressing the issues, as he is the grown up. So find a room or space that crafts are allowed. You can get plastic covers easy to clean, easy to clean floors, even desks that close on themselves, so you can leave it all there and it will not bother anyone.
He needs to find himself a way to chill in the house, his silent space. You all need to respect that space and time, especially if it is his work space.
Your DH could try to help with crafts and singing, joining in, at least sometimes. And praise them. Most teenagers spend ages on computers!
You need to back your husband on if your son is ever rude to him. He needs to be told each time and apologise.
Also you say your son thrives on structure, so try to get to a firm structure at home to, like from such to such hour homework, then snack, then crafts, then dinner. Then reading and listening to music on headphones, watching tv together, but quietly. Your DH can have his chill time then. Bath or showers, bed.
Or have you tried all this with no success?
