Impeccably designed by award-winning Ingui Architecture and meticulously renovated by BZJ Construction, this exquisite Brooklyn townhouse seamlessly blends historic elegance with modern luxury. Heightening the uniqueness is its thoughtful sustainability, and adherence to strict energy efficiency standards affording a Passive Home Certification. Attention to detail is evident from the moment you approach. The beautifully restored fa ade and stoop are embellished by handsome architectural elements, custom ironwork, and a classic cornice exuding curb appeal.

A generous living/dining room enriched by gorgeous oak herringbone floors and a marble fireplace connects through an open archway to a state-of-the-art chef's kitchen. Culinary quarters are gourmet-worthy, featuring premium custom wood cabinetry, sleek marbles named Crazy Horse and Viaveneto, top-of-the-line appliances Miele, Wolf and Sub-Zero, and two wine refrigerators for favorite vintages. Floor-to-ceiling glass doors invite in abundant light and open to a Juliet balcony offering an outside-in view of lush greenery. Nearby is a convenient coat closet, and chic guest powder room adorned with a black Belvedere Leather Quartzite counter. A spiral staircase off the kitchen brightened by a double-height window descends to the great room, and alfresco dining in the rear yard. A magnificent custom mahogany staircase weaves through every story of the house, rising next to the full-floor primary suite. The fabulous king-size bedroom presents its own large terrace overlooking the garden, accessed by oversized sliding glass doors. This retreat has a huge walk-through closet with room for many wardrobes, and an indulgent five-fixture spa bath with dual sinks, marble flooring, and a private loo. Refresh in the Rosa Aurora Macchia Vecchia marble shower, or soak in the deep tub beneath sun-filled southern windows. A smaller bedroom sharing this floor is ideal as a nursery or office.
