No townhouse in Brooklyn is immune from the condo conversion craze.  After a while the wide plank floors, exposed bricks and waterfall counters all begin to look the same.  But this particular conversion on Union Street in Carroll Gardens caught our eye.  

341 Union Street is a four-story turn-of-the-century townhouse that has been converted into four floor-through residences.  The penthouse apartment, stunning in its own right, delivers a knock-out punch with a glorious private roof deck.

Built 25-feet wide, this timeless townhouse has an elegant facade with a mix of classic red brick and historic brownstone.  The stone front stoop bends outward at the sidewalk adding a bit of elan to the exterior.   Stone keystones and sills as well as an extended cornice with an ornate frieze add additional architectural charm.

This three-bedroom penthouse offers 2,350 square feet of gracious indoor and outdoor living.  The great room extends 30 feet across and includes a spectacular open horseshoe shaped kitchen.  And while the home retains a bit of old world grandeur, we can assure you that the original occupants did not have an HVAC system with NEST controls, radiant heated floors or recessed lighting.  A wood-burning fireplace with an original 19th-century marble mantle and floor-to-ceiling distressed bricks serves as the focal point. Wide plank white oak flooring, crown molding and solid core doors complete this devine space.

The custom kitchen features inset cabinetry, Calcutta gold countertops and backsplashes, breakfast bar and top-of-the-line integrated appliances.  

There are three bedrooms, two of which are at the rear of the apartment.  The master bedroom suite has a north-facing balcony, walk-in-closet and an en suite marble bath with double sinks and a large stall shower.  The third bedroom is situated at the front of the apartment and could also be used as a home office or possibly a dining alcove.

The deck, which pretty much mirrors the floor plate of the apartment itself, measures just over 1,100 square feet and sports sweeping views of the city.  Whether you wish to seek a bit of privacy or wish to entertain, this is a private outdoor space that knows no bounds. The roof is accessible via a straight stair from the living room.  

And if you want to get your luggage out of the way, the apartment also comes with a private basement storage room.

This penthouse is currently listed at $2.2 million (about $1,802 per interior square foot) through Alexander Maroni, Jack Chiu, and Lina Chen at Douglas Elliman.  For more information on this special residence, please visit Linecity.com.
