The building where Alex Rodriguez and Jennifer Lopez have listed their condo for $17 million is considered the tallest residential building in the western hemisphere, but it has some strong competition for the title when compared to this nearly topped out supertall tower at 111 West 57th Street. It will rise to 1,428 feet thanks to its ornate decorative top piece, which makes it a tad taller than the 1,396 feet of 432 Park Avenue (where the newly engaged Rodriguez-Lopez duo have a listing and where its developer hung a huge banner proclaiming his love for his fiancée).
