Description

Welcome home to 100 Sixth Avenue, a rare 19th century two-family Brownstone situated on one of North Slope’s most desirable tree-lined blocks. This 20-foot-wide Townhouse has been thoughtfully restored and reimagined — customizing old-world craftsmanship with modern luxury. It sits on a landmarked block with 5-levels including seven Italianate marble mantels, four working fireplaces, original oak floor with mahogany inlay, mulit-zoned HVAC; all on a rare oversized 105’ deep lot. The home is currently configured as a 5-bedroom owners Triplex plus basement and 1-bedroom garden rental. The Parlor level, a historical preservationist’s dream, showcases the home’s grandeur. Anchored by its show-stopping entryway and nearly 12-foot ceilings, this floor reveals a symphony of architectural detail — arched doorways, custom plasterwork and intricate crown moldings. Designed for entertaining, this level includes a separate grand dining room, two working wood-burning fireplaces, a chef's kitchen with custom walnut floating shelves, polished concrete countertops, ample storage, dishwasher, oversized Thermador fridge + gas range as well as the home's sprawling living room. The floor flows seamlessly out to the home’s two private outdoor spaces – the terrace and a uniquely private bluestone garden. The English-style garden spans over 40’ in length hosting perennial plantings with walls of ivy - all inspiring Brooklyn privacy and calm. The second floor continues the theme as a design-driven sanctuary with two additional working fireplaces and two bedrooms, one of which is the double-sized primary suite. It is lime-washed in soft sage tones and layered with custom millwork, organic textures, and warm natural light. The room has a walk-in-closet fit for fashion. Every element feels intentional — from the proportions of each room to the curated light fixtures — resulting in a rare balance of luxury and comfort. Three additional bedrooms sit at the top floor – a skylight lit enclave with walls of windows front to back. Two of the bedrooms have vintage working marble sinks. This floor includes the laundry room. Downstairs is the cellar - hosting over 800SF of additional space. With six restored original brick arches and over seven feet of ceiling height, this floor offers rare architectural depth, flexibility and character. It is currently used as an art studio, gym and wine cellar. 100 Sixth Avenue is a rare combination of modern luxury with timeless intention. Every window has been upgraded to Marvin, ushering natural light through each level while preserving the Townhouse’s original proportions. The interior palette balances texture and tone — cle’ ceramic tile underfoot, hand-restored millwork, and artisanal finishes that bridge the past and present with quiet sophistication. This building includes a high income producing one bedroom apartment. Lot dimensions are 20’ x 105’ and building is 20’ x 47’. The location is also rare – a flawless Trifecta of Park Slope, Prospect Heights, and Fort Greene. Situated on a landmarked block, the house is near numerous subways, BAM, Prospect Park, an abundance of shops and restaurants as well as the Brooklyn Botanical Gardens. 100 Sixth Avenue captures the best of Brooklyn — history, convenience and artistry — a timeless home that tells its story beautifully, one arch, one fireplace, one window at a time.
