Property Details
Description
Presenting a once in a lifetime opportunity to own a rarely available, double loft space on the top floor of the former Ex-Lax Building in Boerum Hill. Units 4H and 4J are joined by an arched doorway and according to the offering plan, comprise approx. 1,738 square feet of interior space. The two adjoining units have been owned by the same family since the building converted to coop in 1980.
Entering the luminous space, you are swept up by the light and high ceilings of this true loft, experiencing the creative vibe that gives loft living its unique reputation. With its 11 south-facing windows, many with a third clerestory arched panel above, beautiful light sweeps across the nearly 50 foot width of the unit.
Entering the foyer of unit 4J you pass a large walk-in closet as make your way to the open dining area, adjacent to the expansive, light-filled living room.
Through the archway into unit 4H, which was formerly used as a huge bedroom suite, you'll find space enough to create several more bedrooms as well as another bath and laundry area.
Apartment amenities: The newly renovated kitchen features granite countertops, stainless range, refrigerator and dishwasher, a glass tile backsplash, as well as abundant clean white cabinetry providing ample storage. The two full bathrooms have been redone, each with a whimsical water theme - a mural of swimmers on the ceiling of one and a vintage etched glass panel depicting undersea life has been installed as a light producing transom in the shower stall of the other.
The building: Converted to lofts in 1980, the coop has a live-in superintendent and a full-time porter. There is a large landscaped common roof deck for all residents. The building is wired for FIOS. Bike storage may be available and occasionally a parking space comes up for purchase within the building. There is a common laundry room but a list of energy efficient washer/dryer models may be approved by the board for installation in the unit. Dogs are allowed on approval. Maintenance includes RE taxes, heat, water and gas. The tax deductibility is approximately 48. Proposed alternate floor plan could include 3+ bedrooms, a powder room and laundry area.
