Designed in 1887 by the legendary architect C.P.H. Gilbert at the height of the Romanesque Revival, this extraordinary residence offers more than 8,200 square feet of interior living space and over 1,200 square feet of private outdoor space across five magnificent levels. At more than 32 feet wide, it ranks among the largest historic townhouses in Brooklyn, and among the very few to retain both its original footprint and its extraordinary architectural detail. As just the fourth family to steward the home since its construction, the current owners have meticulously restored and maintained the property. Modern comforts have been introduced quietly, without disturbing the craftsmanship and bold lines that define the home's era. Original woodwork, rich mahogany paneling, stately oak entry doors, and hand-finished details reveal a level of artistry rarely seen today. Ten wood-burning fireplaces anchor the principal rooms, lending warmth and gravitas to spaces designed for both formal entertaining and daily living. The parlor level unfolds with impressive scale: a grand entry hall anchored by a monumental mahogany fireplace, a formal dining room, and a sun-filled living room. A generously proportioned kitchen with a bright breakfast area overlooks the garden. Above, the private quarters feature a luxurious primary suite with a terrace, sitting room, study, and expansive bath, along with several additional bedrooms, full baths, and laundry across the upper floors. The top level reveals a dramatic loft-like two-bedroom residence with 12-foot ceilings, exposed beams, skylights, a fireplace, and its own kitchen and laundry - evoking the character of a refined European atelier. On the bottom level, a spacious two-bedroom garden apartment with direct backyard access offers exceptional flexibility for guests, staff, or extended family. Behind the historic facade is a fully modern infrastructure. The home has undergone comprehensive upgrades, including central air conditioning, extensive new electrical systems with high-capacity risers and panels on each floor, new brass and copper plumbing, reinforced structural elements, a rebuilt central staircase, and a recently installed boiler. These improvements ensure contemporary comfort while safeguarding the building's architectural integrity for generations to come. Bathed in natural light from multiple exposures and framed by lush outdoor space, 842 Carroll Street offers a rare union of scale, history, and effortless living. Rich with original detail, it is not simply a townhouse - it is one of Park Slope's great private homes. A property of this stature appears only rarely, and once claimed, may not be available again for generations. ## Property Details - **Property Type**: Apartment - **Beds**: 12 - **Total Baths**: 9 - **Rooms**: 18 - **Sqft**: 8,200 sqft - **Stories**: 4 - **Year Built**: 1901 - **Price per Sqft**: $1,817 - **Listed On**: Sep 30, 2026 - **Days on Market**: 2 Days ### Residence Features - In Unit - Garden - Private Outdoor Space Over 60 Sqft - City ## Estimated Monthly Payment **$75,343 / month**, assuming a 20% down payment ($2,980,000), a 6.5% interest rate and a 30-year term.

We calculated the tax for those years using the prior year’s rate, so treat them as an estimate rather than a figure the City has adopted. Every rate without the Estimated marker is the published one. Tax Assessment is the assessed value on the City’s roll, and it is the figure other listing sites publish. It is not what the bill is calculated on. New York phases assessment changes in gradually for some tax classes, so the City bills the Billable Value shown beside it, less any exemption the owner holds. It usually trails the assessment, and it can sit above it for a few years after an assessment falls. Figures are the New York City Department of Finance assessment roll for tax lot 3010720011. Assessed and billable values are determined by the City for tax purposes and are not an appraisal or an estimate of market value. Tax classes and rates are set annually and can change.
