The reason the atrium doesn't snap correctly, is because you're using floors (which go at the bottom) and they are only supposed to be for the middle tiles, not the walls. For those you use the atrium bottoms, which include both wall and floors. For higher floors, there's a different kind of tile called "hanging floors" which snap between two floors. Then there's "ceiling & floor" which you use to extend them.

"It's not as big as you think." Thanks, Davey.

I do hope they update this DLC because there are many many things that are left out. No stalls for toilets etc... And in utility thre needs to be the same kinds of pieces as domestic. There should also be atrium high ceiling extensions to make a wider atrium.

1x1 bathrooms can be made using the domestic tab. put down a Hallway and doorway piece with a wall end cap. it forms a 1x1 room for bathrooms, utility closets, etc.

Unless you scrap literally everything in all of the tunnels, and use the big prefab atrium sections instead of lots of little pieces, you'll hit your settlement build size cap long before you've finished building and furnishing a decent-sized vault. You should scrap those two enormous water towers in the main chamber too, they don't do anything useful and give a decent amount of steel. If you search down one of the tunnels you'll find a big yellow Vault-Tec water pump, which supplies 100 water for 20 power.

Easily the best video on this DLC, made it look so easy and gave tips! Thanks man!

The snapping issue you mention about 4 mins into the video is because you are using the base atrium floors, that are intended to be placed ground level instead of at elevation, when the game intends you to use the "hanging floors" that have support points for floors above ground level.

I know I can count on you to make this seem doable. I was so frustrated by this area after I finished the DLC portion. Putting all these pieces together to make a "proper" Vault was a nightmare. Thank you so much for posting this!! =)

This really helps I've been confused by the DLC immensely thanks for the help and hope to see more.

Thanks this was helpful. Was getting stuck on what to do. And your video is the only one out of many that actually explains properly how to build. While everyone else just does things without explaining it.

I actually had problems coming up for an atrium with the massive vault space, and this really helped on what to make. Thanks!

Just stumbled upon your video after spending a few frustrating hours trying to figure out how to snap everything together. Thank you for your clearing up how snapping works . Cheers!

I found this video to serve as a great boost in the right direction with my build, but there's a few things I noticed that may/may not be helpful for anyone else: You can make the atrium longer by a bit if you build north-south instead of east-west direction, because the build size of that main area is roughly 12 by 17 tiles, though it tapers a bit on the south end. Also, there is actually enough room height-wise to make the atrium 3 walls high (one more than shown in this video), hence there being "lower" "middle" and "top" wall pieces. And finally, when you do make the atrium maximum height, I noticed that the lights that are installed at the top of the cave ceiling helps to illuminate the high ceiling of the atrium a little.

Love that Metro: Last Light idea, that was also going through my mind while building the atrium.

Thanks for this. I was having a lot of trouble figuring out how all the atrium pieces go together.

Thaaaaank you for the 2x1 room tip (and to Cliff Smith below for the 1x1 one as well)! It was driving me nuts to not be able to make bathrooms smaller than 2x2. And also, the build order tip. Such a simple thing, yet one you don't really think would make a difference, and then it turns out it sometimes makes all the difference in the world.

I was having so much trouble with all the snapping issues with this dlc. Some of what I saw here will probably help me a lot. Thanks.

It would be cool to make an "underground city" out of vault 88.

Thanks for the guide! Instead of leading myself to insanity because this would suck to do at first, I just built what you built and added a few extra rooms👍 good vid

Thank you Dave for this glorious build video, I have literally been constantly refreshing my KZfaq page waiting for your uploads

I love this !! you are a life saver! trying to build a vault was so frustrating! i just didn't know why things wouldn't work. thank you so so much

This video helped me out as I like the concept of building vaults. Thanks, Davey!

Davey, btw. Your comments on not using the prefabs (bottom) while admirable is derp. The Bottom pieces actually have significant texture changes to the walls/doors/windows vs the middle and top

Great vid! Answered all of my questions about Atrium pieces. Thanks!

Thanks for this video. I hope to see more videos on vault building. I about gave up on this place, as I couldn't make the rooms work or connect to different type rooms. This gives me hope.

Thanks a lot for the help, I struggled so much building the atrium. This video deserves a like.

Very helpful. Makes vault building less overwhelming

there are so many weird little things you have to figure out first. I spent an hour just understanding the different pieces and how everything went together. its actually a really cool system. tonight I'm going to start an epic vault! thanks for the tips!

I'm extremely dyslexic so all these shapes and pieces including all the glitching I almost Rage Quit LOL but I followed your step-by-step instruction and it's working out nicely for me thank you very much!

Been waiting for this for ages!!! Finally, im pleased

Thanks for this. I was going nuts trying to work out how to start.

Davey, if you place the railings and whatnot before the stairs, the stairs will snap into the railings filling in that gap (sometimes)

It definitely takes some getting used to and experimentation, but I'm really enjoying the vault building. My goal is to try and connect every area in the caves I can.

Awesome dude! I know what I'll be doing tomorrow. Looking forward to the next video.

I'm watching all of these again in 2022 because Davey will forever be a comforting presence in the world of Fallout 4!

"If the blood doesn't disappear, it'll be a bit of character": Only at Norespawns.

i really needed this, i had no idea how to start my vault thanks man

Man this video was great! Please do a full vault build ^^ I have no clue on how to build mine. and your atrium was amazing.

thanks for the build I didn't know what to do with this room

Very well done walkthrough.

This video has helped me out a lot thank you I'm new to the Fallout Franchise and it was driving me nuts because I didnt know what to do

Building is so fucking wonky right now and there are so many pieces in the "rooms" section that are missing but the new guard posts are EXCELLENT! I'll be using those all over the wasteland

its really easy to end up cramped in that main area so advice to anyone starting out: plan your area at least a little bit, get some corners put in place before you set up the ground floor entirely. it's much easier to add hallways and such when you know exactly where they need to end

Love this! Thanks for the tips and ideas. I can now make an creation of my own!

I feel you on the tiny bathrooms. I've been using corridor pieces, usually single length with a solid endcap. Domestic usually look better than utility, but it's to your taste. it can be a squeeze with a tub in, but for a studio WC it's great.

omg thank you for figuring out the 2x1 rooms.

awesome now i got some more ideas building a vault Thanks!

This video is so underrated. Thanks bro.

thx Davey, your vid got my atrium lookin sweet!

Thanks for the video, now works fine, I'm playing this now.

Thanks for this video! It helps me a lot creating the Atrium. Hugs.

You can build 1x1 rooms. On the far right end of the Domestic or Utility corridor menus you'll find Prefab Doorways and Wall End Caps which will snap together in any combination.

I've been addicted to building my vault. It definitely has some bugs and glitches that need to be fixed. This helped me thank you! And also it pisses me off how you just can't build how ever much you want. They gave you that much space to build a vault but you can't build everywhere with vault 88 . :( I hope Bethesda can fix the max limit for building things

I dont understand why so much of the cave space is super tight tunnels. Like how the fuck am I supposed to build a vault through thar?

Thank you for this vid, the vault is so overwhelming and hard to build in at first. Definitely need to scrap my atrium if I want any space. Also last light is a great game

Thank you dude this was super helpful

A pain in the knob! Love it!

Hey man great job this helped a lot! Subscribed keep up the great work

thanks for the help i really needed it.

I like using the Clinic room for bathrooms because of the white tile. I make them 1 by 2. I put down two atrium floors first, then attach two domestic wall end caps to the atrium floors. Then I remove the atrium floors, leaving the endcaps hanging, and put two of the clinic room pieces where the floors were. It basically lets me close off the clinic room using end caps that wouldn't normally snap to them if I put the room pieces down first. If that makes sense.... ;-).

Thus video is just what I needed thanks !

Learned heaps from watching this, subscribing to you mate lol thanks heaps

28/07 Junk still sinks. Patience and supplies running low, as they keep disappearing into the ground. 29/07 Everytime I load in and out of Diamond City, junk in Hangman's sink. This may be my last log. Should've told the family I love them.

You can use the domestic or utility pieces to make 1x1 rooms or you could make a big bathroom (like the one you might have in your workplace or school) that don't look so weird when they are big

thanks a lot for those tips it was driving me crazy trying to figure it out! For some reason the pieces just didn't seem to want a snap for me

In the Atrium areas of my vault I use the wood floor from the Wood tab for the floor. The wood doesn't naturally snap to the walls, but it will snap to the atrium floor pieces.

thank you!!! I didn't realise the settlers always spawn in there and I had an elevated atrium, they kept spawning in the supports underneath. Hopefully building a lower level on the Atrium will solve my problem.

That area is huge I mean when you go down the other wings, there so much room to build stuff XD. I built my living rooms down one of the wings down there. Cafeteria near the atrium and the clinic down the north wing.

Enjoying this for the good use of vocabulary makes it a lot more funny to watch

your doing great man! Hopefully your KZfaq career works out!

I'm going for a metro kind of vault too, using the new doors they added to at the other entrances to the different sections.

just a quick tip @norespawns if you do a bit of exploring down there you will find curcuit boards ther are 4 or 5 five i think, but they will allow you to use workbenches in other parts of the cavern

thanks. this was incredibly helpful, and I agree. metro is awesome.

btw something i learned when using the stairs - and i compared this to other vaults in the game - you want to use one of the two tilts where the railing bends away to the sides, if you use these ones, the railings will nicely connect to railings left and right if you add any there - it looks better then just using either of the rounded end pieces or using the normal ones and have two metal rods sticking out - ppl will would and could impale themself on these~ tl;dr use the additional floor tile in the railing tab for nice looking railing connections, but have longer stairs as a malus.

Do you plan to make some videos for how to make a proper Vault Cafeteria, or Vault Casino room? It would be nice to see how you implant your creativity into the dlc.

Thanks Man You're An Awesome You-Tuber.

why didn't you do this the day it came out lol. it has done my head in.checking what snaps with what took me about 4 hours than I had to start my again. good video bro

My Atrium is Huge (titter ye not), 3 floors with two 3x3 rooms on each side on each floor plus large rooms at each end on each floor (including a 2 story room for my character) plus 2 additional floors of utility rooms that are behind the Atrium roof where my power plant sits. I still haven't fully completed some of the rooms but I have a Hydroponics section, Clinic, Cafeteria, Common Room, Gym, Bathrooms (which I will now edit based on some of the comments seen here) as well as an Overseers office. I haven't expanded past the first cavern (although I did hook up power to the water system) and have already way more space than my Vault Dwellers seem to need. If I could find time to work out how to make videos on the Xbox I would post up a quick tour. Got some good tips from your video though. Thanks!

I needed this soooooo bad

thank u for making the hardest and most hard to understand tutorial that i have ever seen......

you could build some sort of metro 2033 shanty town down there

For bathrooms and such I use the domestic tab hallway&door thing then snap a wall piece at the end

For the bridge you have used a 4 way crossing. There is a 3 way crossing, which would look a lot better.

Thank you so much bro!!👍

If you don't use the pre-fabs then you need a lot more pieces, which uses a lot more of you're settlement budget, and you might think "Oh well I can just cheat, or use glitches, or use a mod and get a bigger settlement" the problem with that is the more pieces not only does it use more budget it also completely rapes your performance

I am super stoked that the vault tec dlc allows you to build big and clean things

Put in the stairs after the railings, that helps a bunch with the snapping.

I've decided to build a regular looking vault, then redesign it to make it look like my character has found it and taken it over, then for the rest of the place make undrrground shanty town-like structures, this area would be the perfect and most realistic place to use the boxcars for building structures

well now i have to scrap everything I've done :) you inspired me.... lol

the atrium as bathrooms, I like that. i need to mess with this because I have rebuilt my vault 8 times and each time I just dislike the overall thing due to the atrium being more than anything, useless and the wrong way so putting things off of it becomes a literal pain.

Good video. Thanks. Love your Brit accent and sayings like "Pain in the knob".

With the atrium end pieces you have to make the atrium one deeper because walls don't snap perpendicular to the end pieces to create a corner. And now your atrium is fucking enormous.

Can you do a video on how to light the atrium you built in this video? A way to light the atrium so it looks good and it's relatively bright.

the wall mid and the "prefab" wall lower have different looks. the mid wall doesn't have a bottom trim while the bottom wall does. It's more of a hassle but it looks nicer

Like it, saved my hair from being pulled out!

Love the use of the word "querky".

Yeeeaaahh I'm not sure what Bethesda was thinking making the opening cavern wider than it is long. It means if you want a huge atrium you need to snake the entrance around so it starts 90 degrees from the "opening" Or have the the entrance to the atrium on the side of the atrium. Or have the overseers office on the side.... Like... why? ungh

I think the best way to use the space is making a big vault in the atrium and littler different vaults in the other sectors you unlock.

+norespawns I fiddled with this way longer than necessary. I haven't even placed down the overseer's desk yet but i figured out that you can use/connect MOST of the warehouse and concrete floors, the first warehouse stair, and the triangle concrete floor in certain areas. I want to use as much of the build space as possible so i made a little secret room back up against the initial wall above the attrium. I'm going to try and make it inaccessible by settlers. I did have to use the concrete pillar glitch to line up a concrete floor piece to get it flush but it's possible. I built my attrium much bigger but now I see I should consider scaling it back. Maybe you can make a video after testing the different floor pieces out to see which ones work best to give us some more ideas.

actually this vault can be gigantic if you've activated every section; It stretches from the entrance to university point pharmacy to Milton general hospital, so it's one of the largest settlements.
