Perched atop a classic 25-foot-wide Carroll Gardens brownstone, with 12-over-12 paned casement windows framing unobstructed views of Carroll Park, this three-bedroom duplex penthouse at 241 Carroll Street offers something rare in Brooklyn: over 1,200 square feet of private outdoor space spread across three terraces and a balcony. The open-concept main level combines living and dining into one continuous, light-filled space with over 10-foot ceilings, central AC, and refinished six-inch wide-plank oak floors running throughout. Two large windows overlook Carroll Park, framing leafy treetop views for a set-back-from-the-street feel. The chef's kitchen is outfitted with Carrara marble countertops, white shaker cabinets, a Bertazzoni range with pot filler and vented hood, a Liebherr refrigerator with double-drawer freezer, and a built-in Summit wine fridge with integrated cabinet wine rack. A vented washer and dryer is integrated into the layout. A whole-home Sonos system extends from the interiors out to the main primary bedroom terrace. The standout rear bedroom on the main level is generously scaled, with floor-to-ceiling windows, custom built-ins and closet, finished with a private stone-tiled balcony set right among the treetops. A second well-lit bedroom looks out over Carroll Park. A full bath completes this level, featuring a Carrara marble vanity and Kohler tub. Upstairs, the primary suite is its own sanctuary flanked by two distinct outdoor spaces on both sides. Thoughtful details elevate daily life including custom built-in closets with bedside niches. The primary bath features Carrara Bianco basketweave marble mosaic floors, porcelain tile shower walls and wainscoting, Kohler shower fixtures with a sliding glass door. The rear terrace is intimate and private, while the front unfolds into a full multi-level outdoor experience, outfitted with a wall-mounted TV over custom built-in cabinetry, built-in banquette seating, a pergola, gas grill, built-in propane fire pit, and Sonos surround sound. Additionally, a staircase leads to a private roof deck, an elevated escape with sweeping views of the Manhattan skyline and the park below, plus space for al fresco dining and open-air lounging. Carroll Gardens is one of Brooklyn's most coveted neighborhoods, known for its historic brownstones, tree-lined streets, and a restaurant scene that draws diners from across the city. Court and Smith Streets are lined with neighborhood institutions like Lucali, Frankies 457 Spuntino, and Bar San Miguel, alongside newer favorites like Cafe Spaghetti and Swoony's. Boutiques, cafés, and weekend farmers markets are all within easy reach. And directly across the street, Carroll Park anchors it all with greenery and the easy rhythm of neighborhood life right outside your door.
