Description

Situated on a desirable landmark block, 105 St. Marks Avenue is a beautifully restored 1873 Italianate brownstone offering exceptional scale and brilliant, sun-drenched interiors across all four upper stories. Measuring 20' x 50' on an extra deep lot, this single-family, five-bedroom, three-bathroom residence benefits from its position on a wide street with expansive rear gardens, resulting in an abundance of natural light from top to bottom.

The home strikes an ideal balance, meticulously retaining stunning original details while executing substantial, highly considered modernizations. The parlor floor is defined by elaborate original plasterwork and fluid architectural transitions that create a seamless flow through the grand, open entertaining areas. At the rear, the modern chef's kitchen commands the space. Designed with remarkable scale and utility, it centers around a massive stone-topped island and custom wood cabinetry. The professional-grade appliance package includes a Blue Star Range, a 42" Sub-Zero refrigerator, dual wall-mounted Miele ovens, twin full-size Miele dishwashers, and double sinks.

The third floor functions as a dedicated primary suite. It features an expansive, full-width front bedroom and a rear bedroom currently used as a substantial home office. A former third bedroom has been smartly repurposed into a custom-fitted walk-in closet. Accessible from the suite's central hallway is a full bathroom. The top floor mirrors the footprint below, offering an oversized front bedroom, two rear bedrooms, and a full bathroom.

Downstairs, the lofty and bright lower level offers two large seating areas and an array of built-ins, including a dedicated workspace. This level also features a beautifully renovated full bathroom with a stone-topped custom vanity and a large shower. The space flows seamlessly out to the home's massive rear garden, a beautifully established sanctuary with a lovely patio, a large sweeping lawn, and mature planting beds.

In addition to the upper 4 stories, there is a basement which offers a tremendous amount of storage space. There is also an area under the stoop for bikes, scooters, and more. A large laundry room is located on the garden level and there is an ultra-functional pet pantry tucked into the basement. Significant structural updates include a complete re-brownstoning of the landmarked facade.

Serenely positioned mid-block, this home places you moments from the vibrant dining and cafe culture of Vanderbilt Avenue, the weekend farmer's market at Grand Army Plaza, and the green spaces of Prospect Park. Nearby beloved cultural institutions such as the Brooklyn Academy of Music, the Brooklyn Museum, and the Brooklyn Botanic Garden offer you unparalleled, local access to world-class destinations. This extraordinary neighborhood setting, combined with the home's historic grandeur and modern utility, creates an exceptional townhouse living experience.
