What's up with the house???

I thought that the movie was ok, but what's up with the new house??? It is in several areas of completion. One part does not even have exterior sheathing on it and one part is insulated. The bathroom floor was missing, supposedly for a bathtub. If that was the case, what is supposed to hold the bathtub up? The only hole needed in the floor for a bathtub is for the drain, a hole about the size of a football or so. The house did not have windows or shingles, yet part of it had drywall and part of it had insulation (as mentioned before). If the house was not weatherproof, neither insulation ro drywall would have been installed. Not to mention plumbing and electrical need to be done for insulation and sheetrock, too. Also, some of the rooms had doors on them. Interior doors are one of the last things installed. They are installed with the finish trim, after drywall, paint, carpet/linoleum, etc.
