New idea, although I believe other games have it allready.
Houseware constructions:
How would you like your house to have a comfortable bed, nice sofa, or at least a dinner table with chairs. Houseware constructions would be craftable items that sit in inventory until you "activate" them. Once activated, they would appear right in front of where you are standing, on the ground (only would work while you were within your own building on your plot) At this point you could rotate the item or otherwise orientate and slide it around until it was just where you wanted it (right next to the wall, or in front of the fireplace) Then you would click the "Activate" button on your build screen and the item would be permanently placed there. Would be similar to building the decorations, but would be placeable within the buildings, not just on empty space in the plot.
