"Bulding a castle" quest - bugged?

[Jantravolta]

So i build a room in my castle... i saw the roof appear. But no completion of quest. Anyone know if this quest is bugged, or am i doing something wrong here?

Do you have a floor all the way from all walls no coffin on ground in middle

You need to walk inside a completed building for the quest to complete. If it still isn't, desconstruct, make sure you've got your floors down, and build a 1x1 stone wall box with an entryway.
