This $5.1M sale to the next-door neighbor in #10C is an odd one. Instead of combining the two, a dining room and bath from 10D are being added to 10C, leaving the rest of 10D as-is. Half the dining room goes to expand 10C's living room, with the other half becoming closets. The condo-amendment plans were filed yesterday, at http://a836-acris.nyc.gov/Scripts/DocSearch.dll/Detail?Doc_ID=2010030301102002.
