Added bonus you can paint anything made in Carpentry and Tapestry other than the Dungeon stuff.
Every time you lvl up any of the 3 Newer Skills you will also lvl up your house. Meet the required lvl and you can make a bigger house with the next set of materials like Lithistle Timber and Bronze Nails. Same goes for Paintworks, Carpentry and Tapestry.
So basically I took materials that are already in game and create something new to add to the game and give players something else to shoot for that they haven't done.
I have other stuff writing down for what else could be done but going to hold off and see what you the community can come up with!
