Boasting expansive dimensions unparalleled in Williamsburg, this 25' wide gem is set on a unicorn of a lot, spanning 25' x 124'. Semi-detached with 5 levels of usable space, 191 Ainslie Street proudly presents 2 meticulously maintained triplex residences and a gross estimated SF of 4,664SF. Its coveted Class-1 status boasts remarkably low taxes, resulting in a very rewarding and sustainable long-term asset. The garden triplex comprises 3 bedrooms (situated on the upper level), 2.5 bathrooms, and a rear yard extending over 70' deep. As you step into this inviting home through its private entrance, you are welcomed by a warm and airy living & dining area, complemented by a well-appointed kitchen furnished with sleek Cafe appliances. Adjacent to the kitchen lies a newly minted bathroom with a shower, while the opposite end of the private hallway grants access to both the backyard and full height cellar spanning approximately 890 SF, ideal for storage and laundry. With multiple outdoor space in the front and rear yard spanning roughly 1,600 SF, opportunities abound for outdoor fun, gardening, or simply relishing the fresh air. Envision hosting barbecues, engaging in recreational activities, or indulging in al fresco dining amidst this private haven after a long day. Accessed via another private entrance, on the front porch, the upper-level triplex showcases an inverted layout, featuring a completely open-concept living area and roof space on the top floor with ceilings soaring over 10 feet high. Currently configured as a 2-bedroom with an office (convertible to 3), this residence features a private foyer, 2 full bathrooms, in-unit washer/dryer, and abundant natural light streaming in from 3 exposures.

Choose wisely between maintaining the existing, income-generating two-family configuration or seamlessly transforming the property into a colossal single-family masterpiece. While the above-grade/legal Floor Area Ratio (FAR) stands at approximately 3,774 square fee plus 890Sf cellar, the Max FAR of 2.0 presents a rare opportunity to expand the current footprint and potentially add up to 2,400 SF (to be independently verified by a qualified architect and/or engineer).
