Property Description for 670 Union Street, 4-A

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.

Park Slope | Brooklyn

Quick Profile

Boasting beautiful tree-lined streets, brownstones and a range of activities for all age groups, Park Slope is consistently ranked as one of New York’s most desirable neighborhoods. Filled with lush parks and greenery, the neighborhood is also known for its rare combination of excellent public schools, award-winning restaurants, nightlife, small independently owned businesses and community gardens.

Situated at the western slope of Prospect Park, the neighborhood is divided into different sections: North Slope, Center Slope and South Slope. Depending on who you ask, of course, the definitions of where these borders end and begin may vary (is the divide between North and Center deemed Union Street, Garfield Place, 1st Street or 3rd Street? The one between Center and South 6th Street, 9th Street, 11th Street or 15th Street?). 

Regardless of what part of the Slope you find yourself on, there’s no shortage of architectural beauty. From row houses to brownstones to mansions, the idyllic setting of the neighborhood is further enhanced by its Romanesque and Renaissance Revival styles. Case in point of this is also two of the area’s most well-known churches, Park Slope United Methodist Church and Saint Augustine Roman Catholic Church. 

Revered for its family-friendly appeal, Park Slope is often regarded as one of the best places to raise a family in New York City. That said, it doesn’t mean that parents don’t know how to have a good time... a slew of bars constantly opening in the neighborhood ranging from the high-end cocktail saloon to the dive (well, by Park Slope standards, anyway).
