Presenting the first resale opportunity at Timber House, the groundbreaking Park Slope condominium from the celebrated Brooklyn Home Company. Residence 3A is a meticulously designed 1,395-square-foot, two-bedroom, two-bathroom home that represents a new paradigm for sustainable luxury living in New York City.

Upon entering, you are greeted by an expansive great room designed for both sophisticated entertaining and tranquil daily life, with soaring ceilings and wide-plank white oak floors creating an atmosphere of airy refinement. Every window is triple-glazed and Passive House-quality, blocking outside noise. The open-plan chef’s kitchen is a model of functional elegance, featuring custom, hand-painted cabinetry, integrated Bosch and Liebherr appliances, and a stunning honed marble countertop and backsplash that seamlessly blend form and function.

The primary suite serves as a serene private retreat, generously proportioned and complete with a spacious walk-in closet. The en-suite bathroom is a sanctuary of its own, finished with bespoke mosaic tiles, a custom vanity, and a glass-enclosed walk-in shower. The second bedroom is equally well-appointed, offering flexibility as a guest room, nursery, or spacious home office, and is situated adjacent to a beautifully detailed second full bathroom.

Timber House is a landmark in sustainable architecture. As one of the city’s first mass-timber buildings, its construction from cross-laminated timber offers superior thermal and acoustic performance, promoting a sense of wellness and quietude rarely found in urban construction. This Passive House-inspired design results in significantly lower energy consumption and a healthier living environment.

With only 14 residences, the building offers a distinct boutique and private feel. Residents enjoy access to a beautifully landscaped common roof deck with panoramic views of the Brooklyn and Manhattan skylines. This sale includes a private storage unit. For added convenience, a deeded parking space equipped with an electric vehicle charger is also available for separate purchase
