The property at 921 Carroll Street in Park Slope hit the market this week at $18.5 million, making it among the most aggressively priced single-family listings in Brooklyn at the moment.

The seller is Lillian Heidenberg. The house is a double-wide Romanesque revival townhouse — the kind of exterior that stops foot traffic on Carroll Street — with interiors that include a private elevator, formal entertaining rooms, and what listing materials identify as an Alex Katz work on the premises.

The building runs four floors. The elevator services them.

Park Slope has seen its share of ambitious townhouse asks, but the Carroll Street listing adds the Katz to the comp sheet alongside the cage lift, the arched facade, and the kind of eat-in kitchen that real estate copywriters describe as “chef-caliber” without specifying which chef.

At $18.5 million across four floors, the elevator is doing approximately $4.6 million worth of work per landing.
