I retextured a house mesh that I don't own and tried to make it as similar to your picture as possible. It isn't great, but maybe this will work as a Santa's workshop?
The fire I have in that fireplace is Thierry's fire.
Here's the download:
http://www.mediafire.com/?27wjlcjk5vgn2fhJust extract the .rar and drag the media folder into your FeralHeart folder, it'll merge with your original media folder and put what you need into the game. Then launch the object maker and there should be an object group called "SantaWorkshop" - that's where the mesh will be. The ground might glitch through the carpet when you first load it up - just lift the house up a little and it'll be fixed.
