Create your own Castle Mod by M7.
Create your own Castle:
Hearthfire & Dragonborn DLC are required.
First off, this Mod was inspired by the "Craft your own Fort" Mod by chrysanthes77.
As Dragonborn, you've inherited this small island near Solstheim, but it requires some fixing up. You will need to make repairs -- for the Wall and Gate, then later add Farms (3), a Horse stable, A General Store (in Gate house), hire Farmers & animals, and build the Castle.
Then you add to the interior -- make furniture: beds, chairs, tables, etc.
All Items can be fashioned from the local area -- Aspen Trees can be harvested for wood piles, Clay and Stone can be mined, and Linen fashioned from a Loom (Tundra Cotton) to make furniture. There is a Cheat Key that accesses the Supply Chests (in case you are in a hurry to build everything).
Tools: Pickaxe, Axe, Nails, Hinges, Fittings, Locks, Wood Piles, Clay bricks, Stone, Glass, Trees, etc.
The items produced give access to keys that unlock small rooms with Levers (I had an issue with Hearthfire because I could not edit the Papyrus Script, so I improvised).
The Island is accessible via the Teleport Spell in Powers section of your Character's Magic list. You are teleported to the Shack, an initial starting point. Another access point is a teleporter in Solstheim / Raven Rock.
