Use this Schematic in the Drafting Table to remodel your house into an Entryway
This is part of the DLC: Skyrim: Hearthfire.
What does Remodel House into Entryway do exactly?
When you use Remodel House into Entryway, it does NOT redesign your house. Contrary to popular belief, you do NOT use it to start over from scratch. What this does, is change the first part of your house to a fancy entryway area, and changes the furnishing available for that room. For example if you have added a wing with a bedroom to your house, you don't have needs for bed in the first area you built, so you might as well redesign it into an entry way to make the Manor more luxurious.
