Michelle Schrank said she is decent at minigolf, the mostly putting game also known as miniature golf that is short on fairways and distance. There are no 300-yard drives, but there are holes in one.

“I don’t get many,” Ms. Schrank said, “but I have good aim.”

Ms. Schrank, 30, considers minigolf a suburban pastime. But when she and another architect, Dijana Milojevic, entered a design competition, they suggested importing minigolf to the heart of Midtown Manhattan — specifically, to the medians in a nine-block stretch of Park Avenue.

Their idea got the attention of the jury in the competition, sponsored by Fisher Brothers, a family-owned real estate company that is a longtime landlord in the neighborhood. The jury named the entry from Ms. Schrank and Ms. Milojevic one of 17 finalists.

Another finalist, Eric Spencer, proposed installing an aquarium — a glass box in a district of glass-box office buildings. “There’s a tongue-in-cheek connection,” he said. “You know, the classic stereotype, guys and gals on their phones, sharks, doing their thing.”
