I tested the mod with the Falkreath Hearthfire house and it seems to work fine, no adjustments necessary for the Special Edition.

Building a house in the Hearthfire DLC can be a very tedious process with having to collect materials, building something, and then having to collect even more materials.  The back and forth can turn people off from building a completed product and using the house.  What this mod does is that it removes the material requirements for all of the things that can be created by the crafting workbenches inside and outside of the new houses added by Hearthfire.  The only things that haven't been altered are iron fittings, locks, hinges, and nails since they no longer have to be created to build a house.  Additionally the food items that can be made in the ovens still have their requirements, and I have also removed the salt requirements from them since it can be hard to find.  

I'm not sure what the issue is with the zip file.  It used to work fine for a while but after a certain point it just stopped cooperating and wouldn't open.  Now it works fine for me, I was able to download it straight to Mod Organizer 2 and install it and it worked perfectly.  Some comments say it still doesn't work so if you're having trouble check out this mod:
