I hate living in a construction zone so all work was done in this house before I moved in. My husband is a engineer and very good at planning and visualizing the final results. We opted for one story so we could age in place. We also made the yard low maintenance. I don’t like a really open floor plan either. I had one once and felt the same as tybee about it. We did remove most of the wall between the kitchen and dining room. Just left a half wall in one area that blocks you from seeing the sink or stove.
