A five-story Park Slope mansion with serious bragging rights is back on the market, carrying a $16 million asking price. The Romanesque-Revival Kenyon House stretches more than 32 feet wide and offers roughly 8,200 square feet of interior space, plus about 1,200 square feet of terraces and garden. The property has returned after nearly two years of on-and-off marketing and several price adjustments.
The listing for 842 Carroll Street is held by Platinum Forbes Global Properties, which names Mackenzie Kyle and Thomas Handschiegel as the listing agents and presents the residence as a single-family mansion. The listing notes 12 bedrooms, six full baths and three half baths, and highlights multiple wood-burning fireplaces and central air, according to the brokerage.
Gilded Age pedigree
Built in 1887 for George W. and Isabelle Kenyon and designed by architect C. P. H. Gilbert, the house sits among a trio of Gilbert townhouses on Carroll Street. That pedigree, along with the detail that the Kenyon family occupied the home into the 1920s, is outlined by Brownstoner.
What is inside
Marketing materials and archived listings describe a parlor-level formal sequence, a primary suite with terrace, a two-bedroom garden apartment with backyard access, and a loft-style two-bedroom fifth floor with vaulted 12-foot ceilings, exposed beams, skylights, a fireplace, and its own kitchen and laundry. Those interior details and room counts appear on the home's marketing pages, including the Elika New York listing.
Listing history and price swings
StreetEasy's price history shows a late-2024 ask near $15 million, followed by a $14.75 million entry in early 2025 and a $12.789 million appearance through the summer of 2025 before the current $16 million relist. Zillow and other brokerage archives reflect the same sequence of listings and price adjustments over the past two seasons.
Why it matters for Park Slope
A trophy house of this scale is a rarity in Park Slope, where median asking prices sit well below this level and truly wide 32-foot townhouses seldom come to market. Local market trackers say the combination of the original footprint, intact detail, and substantial outdoor space makes 842 Carroll Street an outsize listing for buyers seeking historic scale near Prospect Park, according to CityRealty.
Showings are by appointment, and listing materials state that the house has been meticulously maintained. Brokers suggest it will appeal to buyers who want original craftsmanship and room to entertain.
