400 Putnam Avenue

Spanning approximately 4,394 square feet of above-grade living space, with an additional 692 square feet in a beautifully finished cellar, this expansive brownstone offers a total of approximately 5,086 square feet of interior space, delivering a rare sense of scale within a classic Brooklyn townhouse.

Defined by soaring 11-foot ceilings, original pier mirrors, and ornate crown moldings, the owner’s triplex seamlessly blends historic architectural detail with refined modern finishes throughout. A chef’s kitchen, anchored by a full Viking appliance package, opens directly to a private balcony, creating a natural flow for indoor-outdoor entertaining. Gracious living and dining rooms are anchored by five fireplaces, while five bedrooms and a dedicated home office provide exceptional flexibility for both daily living and hosting.

The primary suite serves as a private retreat, complete with spa-inspired baths, in-unit laundry, and direct access to a terrace with hot tub, offering a serene escape within the home.

Outdoor living unfolds across three private levels, including two balconies connected by a winding staircase that leads to a landscaped garden-level courtyard. Below, the finished cellar, complete with a full bath, offers versatile space well suited for a media lounge, gym, guest accommodations, or additional living area, all enhanced by an integrated Sonos sound system.

The garden level includes multiple flexible-use spaces with separate access, including a one-bedroom residence with direct courtyard access and an additional private suite. As currently configured, these spaces offer income of $6,100 per month, providing optional flexibility while preserving the primary residence as a true owner’s triplex.

Set along historic Putnam Avenue, named for Revolutionary War hero Israel Putnam, the home sits within one of Brooklyn’s most architecturally rich and continually evolving neighborhoods. Ideally positioned near Clinton Hill, the surrounding area is defined by tree-lined streets, boutique shopping, acclaimed dining, and convenient access to transit.

Whether envisioned as a grand primary residence, a multi-generational home, or a sophisticated ownership opportunity with built-in flexibility, 400 Putnam Avenue presents a rare offering of timeless Brooklyn living at scale, thoughtfully reimagined for modern life.
