i suggest having a look at the available mods on Telesphoros' List o'Mods
...single best listing of Morrowind mods i've ever seen. you can link straight to the Housing section by clicking here
. you could also look through kwshipman's List of House Mods
...a pretty thorough collect that lists which expansions (if any) are required and provides screenshots.
personally, i've always liked A Good Place to Stay
. it gives you a nice home in Balmora and doesn't require either of the expansions. there's plenty of well-organized storage, as well as an optional mod included that will add a fast-transport feature...pretty nice once you've explored quite a bit and just want to get around the island quickly
