Maybe one of your paved spots has decayed but the map has not yet updated to show that.
Usually when you plough the decayed tiles in an already ploughed field a few more spots suddenly revert to appearing unploughed due to the same kind of a delay. Perhaps trying to plough a ring around your construction site would make one of the stone tiles go back to unpaved. Or you could try putting a stone in inventory and patiently clicking each one of the tiles in your foundation with the paving tool tip to see if they would accept the stone.
After that I would try emptying the cupboards and moving them, although I am sure that is not it.
Also, are you sure there is not a rat or something behind the cupboards invisible making it impossible to put the house down?
