I was referring to the lots facing the wrong direction, as well as the fact that they aren't placed logically within the town and take up some larger lots. Also, there is no continuity with the sidewalks, as the buildings have a border of excess grass around them.
I've spent some time today learning more than I'd like about lots and placement, while moving things around. In a thread on an official forum I found that a common solution was to relocate the housing that currently is next to the spa, and then place the fire station, consignment shop, and salon in their places next to the spa. For me that wasn't a piece of cake!
Then "save as" Sunset Valley Ambitions, and use that save as a starter town in future new games, renaming of course.
