About This Home
As of August 2025Welcome to 343 Prospect Avenue! This recently renovated townhome, meticulously designed by architect Ben Herzog, encompasses four expansive floors. This approx. 1,725 +/- sq.ft. townhome offers four generously sized bedrooms, two full bathrooms, two half baths, outdoor space of approx. 850 +/- sq.ft., and an additional approx. 450 +/- sq.ft. finished lower level perfect for a media room, art studio, or more! On the main floor, an expansive open concept layout creates an inviting living area, perfect for hosting gatherings. A true design marvel, the chef's kitchen features a massive center island with seating for four and plenty of room for cooking prep work, fully equipped with a Sub-Zero refrigerator, Bertazzoni range, Bosch dishwasher, and a convenient microwave drawer. Crisp white Caesarstone countertops, custom inset cabinetry, and a honed Calacata Borghini marble backsplash enhance the chef's kitchen's sleek and minimalist design. Flowing seamlessly from the kitchen is a dining area framed by sliding glass doors that open to a spacious and privately landscaped backyard, which gets an abundance of natural sunlight throughout the day. The expansive backyard underwent a redesign to incorporate multiple elevations which include a concrete patio, turf grass area, high fencing, and a rear Ipe deck with wraparound seating and irrigated planters. A beautifully designed powder room adds the finishing touch to the parlor floor. On the secondary level, you'll find the roomy and well-lit primary bedroom accompanied by an en-suite marble bathroom featuring Bardiglio stone flooring, a sleek white sink vanity paired with dark wood cabinetry, and a separate glass-enclosed shower. The primary bedroom conveniently grants access to a generously sized terrace that offers a delightful view of the backyard and open blue skies. The other bedroom on this floor (currently being used as an open home office) can easily be configured as an additional bedroom. Once arrived on the third floor, you'll discover two expansive bedrooms, each equipped with ample closet space to accommodate all your essential belongings. These bedrooms also share access to a full bathroom featuring exquisite Bardiglio stone flooring, a double sink vanity, and a stylish glass-enclosed bathtub. The fully finished lower level extends the living space of this home even further. Embrace your favorite movie or show with friends and family in this cozy and comfortable media room/den. This level also features a convenient half bathroom, an LG washer/dryer, and plenty of storage space. Rounding out this townhome are several additional features, including 5" wide plank oak floors, multi-zoned heating and cooling for optimal comfort, pre-wiring for seamless home automation, custom blinds, top-quality Marvin and Pella windows, fixtures from esteemed brands like Waterworks and Restoration Hardware. Situated just a few blocks away from Prospect Park and conveniently near the F and G trains, 343 Prospect Avenue represents the realization of a dream come true!
