If you like the idea of having a treehouse but want something a little big bigger, take a look at Elvenwood.
Elvenwood is a massive treehouse settlement that's located between Falkreath and Helgen. The developer made sure the settlement is lore-friendly and those looking to learn more about the backstory will find a book with its history.
The settlement itself is populated with various Wood Elf NPCs including a blacksmith and a merchant at a general goods store.
The interiors of Elevenwood's various buildings are furnished and detailed and there's a player home that you can purchase. It comes with storage, a bed, a mannequin, a weapon rack, weapon plaques, a cooking pot, bookshelves, an alchemy table, and an enchanter.
The house will set you back 5000 gold, chump change for most Skyrim players.
Unlike the Hunter's Tree House, this mod isn't available for the PlayStation 4.
