OperatorJack has a wonderful house mod called OAAB - The Astral Pocket that I have used on my previous mage character. Thematically it was perfect and the environment was very cool too. However, I have come with two issues that I decide to "fix":

• The whole lava pools make it incredibly hostile for people using Ashfall. Even inside the housepod there is a lava field in the void (for atmospheric reason) that puts a lot of heat to the character, to the point of preventing long rests.
• Despite being a high level house (due to high mysticism requirement) there aren't a lot of space to put your loot. And if you are like me and use mods that add tons of new stuff, you'll run out of storage space very quickly
  

So I made two different plugins that helps with those issues. You can use them both or only one of them.

1- Green Astral Pocket

Basically I've removed all the lava and cavern stuff and replaced it with grazeland stuff. Now there are waterfalls, trees, and tons of open space to place your own camping stuff. It's perpetually dark with some greenish light so even vampire players are safe in here. Well, not 100% safe since there has to be a way for the old resident to leave it empty.

I'm not sure what would be the consequences of using this on a game you already visited the Astral Pocket. Be sure to take any item you placed outside as they can get buried inside a mesh (those on the table are safe). I haven't touched anything inside other than removing the lava pool so your items there would be safe at least.

This is technically an esp replacer so it has same plugin name. But you still need the original mod for the MWSE scripts.

2- Astral Pocket - Cloud Storage

Rather than increase the space inside the pod, I've decided to make an Cloud Storage addon to it. This way the small, cozy atmosphere of the small telvanni
housepod is not lost while you can dump ever single loot you have in
here. The activators are not placed on existing shelves so you can still
use those and not lose any display space.

It should be safe to add this on your current playthrough.

Installation

You need the OAAB - The Astral Pocket and its requirements for both addons to work as intended. For the Cloud Storage addon, you need Cloud Storage.
