Description

420 12th Street, G1L and Garden

Authentic Brick & Timber Loft at the coveted Ansonia Court

This spacious one bedroom, one bathroom duplex home has a rustic-chic vibe with its cinematic light, soaring ceilings, brick and beams, wood, and warmth. This stylish and recently renovated one bedroom, one bath is laid out graciously on 2 floors with living room, dining and kitchen on the lower level, and the quiet primary ensuite complete with laundry on the upper level, creating an easy flow through the home while separating the public from the private spaces.

Both the cooks kitchen and ample spa bathroom underwent a gut renovation and have a serene and contemporary sensibility. Dramatic oversized doors and clever custom millwork through out help create the efficient loft style vibe.

Al fresco dinners, afternoon cappuccinos and star gazing will fill the days here if indoor // outdoor living is in order. The Ansonia's courtyard culture has a cult following and is a centerpiece of the South Slope.

Constructed in 1881 and designed by architect Samuel Curtiss Jr in the German Romanesque Revival style, the Ansonia Court is a well-maintained pet-friendly co-op, which centers on a private, lush courtyard with towering flowering trees, benches to rest, and completed by a serene water fountain. This pet-friendly building has a full-time super, package room, and bike and stroller storage. Located just two blocks from Prospect Park and less than a 5-minute walk to the 7th Ave F train subway line. Neighborhood treats include Michelin-rated Winner bakery, Caf? Azul, Fonda, Pasta Louise, and neighborhood newcomer Ottava for an Aperol Spritz and divine brick oven pizza! You may never cross 9th Street again.
