Another Haven Bag? Yes and no, because these are a little less cramped than the original one.
I know, there are some remakes here that add more functions or  the DIMP, which started out as Display Room and later updated to a full living/crafting space.
I'm glad that I still have the old version in my load-order, as it sadly seems to be deleted.
Now with additional spell and FX for teleport.

This one was inspired by a comment of Fitharia at the Haven Bag - Revamped mod.  
What was needed needed (by myself,too), was a simple place for storing all that stuff that one can pick up in Tamriel for later use, upgrading or selling.
Plain and simple, using only vanilla assets, less than four lightsources (not counting ENB Particles) and the teleport script.

So the Storage Vault was created, a secluded room with 45 chests (or was it 44) and six barrels for food, all non-respawning.
Should be enough for most playthroughs, even if you tend to collect every basket you find on your travels.
The chests are just generic, not sorted or labeled, as that would need at least a new type of container per label, which results in more entrys as I am comfortable with for an ESP-FE. But they are all positioned besides or near crafting stations or put neatly in 4 rows, so you will easily get your own system - like 1rst row weapons, second armor, third clothing, fourth baskets.

Yes, there are all crafting stations of Caithe's original bag plus a wood chopping block (my wife still likes her wood to gold spell).
But there are no extra items besides some food/fish in some of the barrels, but don't worry, that's well preserved and still goood to consume.
At least, if you do not have something installed that let's it turn rotten, which may fit nicely into the Black Vault.

The only script included is a variant of Sticz's evolved Haven Bag teleport script used in his Dwemer Conversion and SkyShrine, which are both highly recommended "bags" for people who like tons of extras. It should take care of your followers, too.
(Not thorougly tested, I only use followers as eyecandy. They are mostly to vulnerable and don't levitate.
 But I accidentally teleported Lydia with me when she was blabbing with my character.)
New in V1.1: Script does not strip slot 60 anymore, which is somewhat obsolete when using a slotless ring or spell.

The first version of the Vault was a purely vanilla asset version, but soon there were some points that annoyed me with two of the used dwemer bighall meshes. They have protruding "tiles" without collision, so your feet clip right into them - I had to hammer them back down in NifSkope.
(Included a replacer for vanilla meshes in otionals. Use at own risk and dont make me responsible for floating statics in your dwemer dungeons!)
Then there was the mismatched color between Blackreach Sun (that orange-coloured pumkin light) and light color. My wife liked the light, so the lamp had to adapt and the third custom mesh was added to the mod.

Of course, my wife wanted a Gilded Vault (she really seems to like that stuff, dunno if it is a hint),
 so the endcap mesh was included in the next set for the Gilded/Brass Vault.

Then the first Halloween Mods popped up in the last day, so a Dark Dongeon or Black Vault was made, too. That one uses Dungeon Music, to fit the spooky theme somewhat.
All of the four included meshes were dark-theme adjusted and the Vault relit in Pumkin color. Very Potato-friendly as it uses the tiny "black.dds" as diffuse.

As usual, visual experience will vary with ENB preset or (Re)textures you use.

That's it, for more Infos look at the pictures.

Have Fun
