Property Description
Timber House introduces a new standard for Brooklyn condominium living, where sustainability, design, and comfort intersect. Crafted using cutting-edge timber construction and thoughtfully layered natural materials, this newly completed three-bedroom, three-and-a-half-bath home offers a modern retreat with an elevated, architectural presence. With 2,041 square feet of interior space, the home is defined by soaring nearly 11-foot ceilings, exposed beams, and wide-plank engineered pine floors by Roots Custom. The open living area is both expansive and adaptable, easily accommodating formal dining, relaxed entertaining, and work-from-home needs. At its center, a refined European kitchen pairs custom cabinetry and porcelain countertops with hexagonal tile flooring by Prospect NY, a walk-in pantry, and a curated suite of Bosch and Gaggenau appliances, including an induction cooktop. The primary suite is a private sanctuary featuring a generous walk-in closet and a spa-inspired Carrara marble bath with a Duravit soaking tub, oversized walk-in shower with linear drain, Restoration Hardware medicine cabinets, and a custom floating vanity finished with Brizo brushed gold fixtures. Two additional bedroom suites each include their own bathrooms, one enhanced by a Juliet balcony and walk-in closet. A powder room, in-unit Miele washer-dryer, and integrated smart home technology-including Lutron lighting, Latch entry, Nest safety systems, and high-speed connectivity-complete the residence. A private storage unit and dedicated on-site parking space with EV charging are included in the purchase price, offering rare convenience in this sought-after neighborhood. Timber House's striking Danish brick exterior conceals an advanced glue-laminated timber structural system that minimizes environmental impact while maximizing strength and warmth. Energy-conscious features such as triple-glazed Passive House-quality windows, solar panels, multi-zone heat pump heating and cooling, energy-recovery ventilation, and mineral wool insulation create a quiet, efficient, and comfortable living environment. Residents enjoy a modern lobby with secure package storage, bike storage, private storage for each residence, and a beautifully landscaped, furnished roof deck with panoramic views stretching across Brooklyn and Manhattan. Timber House offers a rare opportunity to own a design-driven, environmentally responsible home in one of Brooklyn's most dynamic and desirable settings.
