Well, If I lived at Collinwood, I would definetely change those walls. That stone just seems so cold to me. I need a much warmer setting. Would also add more modern pictures on the wall, enough of those old ancestors from hundreds of years ago, I want a home, not a museum. I could always fix up another room just for that purpose, with old pictures, antiques & such. Also, add blinds instead of those heavy drapes. OH! And I would definetely add a TV in the drawing room! Seems odd they never had one in any of the rooms. I guess with all the adventure there, they don't really need one. I also would add wall to wall carpet through out the foyer & drawing room and add more flowers around the house to brightened up the place.
Actually, I prefer the old house anyway to Collinwood. The old house seems much warmer to me. I wouldn't have to change much there except maybe the drapes and wall coloring.
