I found a mod that extends on top of Hearthfire that "adds some new, lore-friendly functionality to each homestead, perfectly integrated with Hearthfire's construction system. With Hearthfire Extended installed, you'll be able to customise your home to whatever design you want. You can build any furniture in any room, build new rooms for your cellar, hire new types of servant for your homestead and hire guards to protect it. You'll also be able to brew mead, milk cows, build a well and much more.
Works quite well with Cutting Room Floor (patch included) and it seems quite compatible for Complete Alchemy and Cooking Overhaul as well.
I suggest giving it a nice look as it could be an excellent addition to the STEP guide.
