A double-width Romanesque Revival mansion in Park Slope, Brooklyn hits the market at $18.5 million. The property, owned by Lillian Heidenberg, spans two traditional Brooklyn lots and represents a rare architectural footprint in the neighborhood.
The home features a private elevator, a luxury amenity uncommon in Brooklyn brownstone territory. The listing also highlights original artwork, including a piece by painter Alex Katz, reflecting the owner's art collection.
Park Slope has seen mansion-scale properties command premium prices in recent years, but double-width homes remain scarce. Most historic Brooklyn properties occupy single lots, making this listing an outlier. The Romanesque Revival style, popular in late 19th-century Brooklyn development, adds architectural cachet that appeals to high-net-worth buyers seeking character and scale.
For sellers in Park Slope, this listing sets a benchmark for trophy properties. The $18.5 million ask positions the home well above typical single-width townhouse sales in the neighborhood, which cluster in the $3 million to $8 million range. The elevator and original artwork signal amenities that justify the premium pricing.
For buyers, the property appeals to collectors and those seeking statement homes. The combination of rare architectural footprint, private elevator, and curated art collection targets a specific demographic: wealthy individuals who value both history and modern convenience. Park Slope's proximity to Prospect Park and established cultural institutions strengthens its appeal to this buyer pool.

In a borough where square footage trades at premium rates, this home's expanded footprint justifies significant pricing power.
