Just off Smith Street and surrounded by the best of Brooklyn, this beautiful four-story home offers a rare combination of scale, natural light, and serenity.

The parlor floor features soaring 13-foot ceilings with original crown moulding details, two original marble-mantled fireplaces, and a gracious double parlor perfect for entertaining or quiet evenings by the fire.

On the garden level, an open kitchen with plentiful storage including a walk-in pantry and center island flows seamlessly into a casual family room and out to a beautifully landscaped, south-facing backyard that has been completely reenvisioned (more on that below!). A formal dining room with an original fireplace and a powder room round out this floor.

Upstairs, four bedrooms plus a flexible fifth room (perfect as an office, nursery, or playroom) and two full baths provide spacious and versatile living. The spacious primary suite includes a private terrace overlooking the backyard. A full laundry room is located on the primary floor as well.

The owners have completed a suite of high-impact upgrades inside and outside, including a new boiler, HVAC units, front door, and appliances. The backyard features a new limestone patio, Ipe fencing and raised deck, irrigation system, and all of the beds are planted in organic soil with a curated mix of apple trees, raspberry and blueberry bushes, a juniper tree, and roses — creating a true urban oasis.

Additional features include multi-zone central air, updated plumbing and electrical, and an updated water and sewer system in the basement. Located just off Smith and Court Streets and one block from the F/G trains at Bergen Street, 90 Dean is ideally located for all the neighborhood’s conveniences.
