This a few years late, but you're awesome

(9:55) You need to dress those dummies as gunners and raiders and other human enemies (depending on which of the major factions you offended).
(11:30) You could create an underground training area, like the one in Vault 75. You could even use traps to populate it with real enemies on cue.
(13:00) You never know. I keep finding legendary Far Harbor weapons in the Commonwealth.
(16:05) Mannequins are weird. Try placing the trunk where you want it and then put mannequins in place. It seems a little more forgiving that way.
(22:30) I think they are called "lanes".

Q&A Have you ever been to a Ozzy Osbourne concert?

You could put dressing rooms in that corner across from the clothes shop. Still use chairs, tables in space

Lmbo you're reaction to the woman at the start was hilarious

I got a creation club mod that gave me bunk beds that count as two beds.  Makes for having more beds in less space.

Q&A: since you like building and decorating so much, have you ever played Sims? If you haven't, would you ever play it? And if you did, did you like it?

1:14 the butch is strong in that one

Tables around columns... think tetris! Left end of table against the column with the right sticking past it, then repeat around the central column. They will end up all matching the right hand end next to the starting left hand end of the next.

I put a room with all corners with doors and didn’t realize it from following at 53:34

your reaction to the very ugly, man like woman cracked me up. lmao

you forgot the Fatman, broadsider and the junk jet

hi, a suggestion/option for your cloths store, I put my manikins on a quarter wooden floor piece, it makes it look like it's on a purpose stand, I also think if you put a quarter floor in the middle of you store area and put 2 wooden, deep shelved short bookshelves back to back on it with spot lights looks good as a hat stand maybe? I haven't started my vault yet but you are giving me some really cool ideas as I too am on ps4 so don't have mods to assist me. keep up the great work :-)

I'd also suggest a game room, pool maybe build a small bowling alley or batting cages

Next to the classroom should be the Nursery :D I know there are no babies but since most vaults have Nurseries you should have one near the classroom. It would be like the Children wing (even though there are no kids :D)

Needs some posters. Those light up ones.

Yahoooo watching this build made me answer a huge problem i had in my own vault by you saying "my place." Now I Know what I'm going to build in the place that i was having sooooooooooo many issues with! Yippee :) :)

have you ever seen a real army barracks if not I will tell there pretty small and cramped so little decorations as possible.

Good stuff so far. FYI at a shooting range they are called stalls. I think you should dress the targets in raider Armor. The picnic table works as it is a common thing at outdoor ranges. Most indoor ranges would have a wall blocking the shooting range from the rest of the building to block sound.

The clothing store and sitting area makes me think of Barnes and Noble or some coffee shop. I would suggest another store as someone else in comments has.

Amazing video again continue your good work and thank you for all the tips you gave
