Hoard saber cat teeth, you use them for decoration, & they are hard to come by.
For a full house with all 3 wings & furnishings, you'll need ~400 logs, ~200 iron ingots, ~20 corundum ingots, ~ 25 steel ingots, ~16 glass, ~25 goat horns, ~12 straw, You'll need other metals & gems for the enchanter, alchemy lab, & the shrines in the cellar; a filled grand soul gem for each enchanter, all of the gods' amulets, 2 deer hides, horker teeth, animal pelts (bears, wolves, saber cats, snow saber cats, goats), mudcrab chitin, 3-4 large antlers, small antlers, slaughterfish scales, & lots of leather strips.
Naturally, the building goes a lot faster when you've already accumulated your materials. You can add the décor later if you don't have all of the materials when you start.
When you build, be sure to make the nightstand for the basic house before you remodel it into the entryway, as it won't show up on your list of decorating options after the remodel.
Save before you furnish each room, as you may decide that you don't need quite so much stuff, & once built, it's impossible to remove without going back to a previous save. I rarely put in all the furnishings.
If you approach your worktable after you've built some things, & the menu hasn't updated, just close the menu, back away from the worktable, approach it again & click on it again; the menu should be updated this time.
