We wrote about the fourth-floor apartment at 27 Schermerhorn Street back in 2011 when it was asking $695,000. Now the top floor unit, which has been redone in a much more modern fashion, is on the market for $915,000. The brownstone floor-through co-op is 25 feet wide and 1,000 square feet in total. Monthly maintenance is $1,218. We’re usually not big fans of going modern in a brownstone but this renovation looks pretty successful to us.
