Description

Perched high on the 9th floor of the pre-war, 11-story Folio House Building, located at 105 5th Avenue, Apartment 9C is a sprawling, loft apartment containing 1 bedroom, 1 sleeping area/office, and 2 full bathrooms that awaits your arrival. This approximately 1,500 SF, sun-drenched apartment contains soaring 11-foot ceilings, central air conditioning with climate control, 7.5" inch wide plank flooring throughout, stunning 9-foot windows, ample closet space, and many original prewar details.

You enter your home and arrive to a welcoming foyer. Bathed in natural light, the expansive living room is for your family gatherings and for hosting social events. The renovated kitchen features all high-end appliances: a stainless-steel Bosch refrigerator and freezer drawer with an ice marker, 2 Fisher Paykel draw dishwashers, a Wolf induction cooktop, a Viking oven, a deep sink containing a filtered water tap, spacious counter tops, ample cabinets and storage spaces. The climate control for the home is powered by Tran that both cools and heats the apartment via 3 separate, owner controlled, climate zones. The serene and spacious primary bedroom features an en-suite bathroom, numerous closets and a large walk-in closet. The primary bath contains all Waterworks fixtures and lighting, which includes an elegant deep and high shower and an artisan basin and vanity with ample storage space. The sleeping area/office is sizable and can be used as a private office for getting work done and a sleeping area for your child or guests. The second bathroom also contains all Waterworks fixtures and lighting, which includes a bathtub with a shower head, a smart and functional sink and vanity with a medicine cabinet, as well as a storage cabinet.

Additional valuable and useful features of this home include: an in-unit Washer/Dryer, a breakfast nook to enjoy your morning coffee and tea, and 2, exclusive use storage units on the same floor as your home. The open floorplan is very flexible which can allow you to add both an additional bedroom and a den, as can be seen on the alternative floorplan design.

The historic and well-known Folio Building is a pre-war co-op that contains only 36 apartments and is built in the Beaux-Arts style. The pin-drop quiet, 9th floor contains only 4 apartments and the newly renovated, windowed common hallway area is pristine. The building is pet friendly and the amenities include: a super and a porter, two elevators and a freight elevator, a virtual doorman which provides security and privacy, a gym, a large laundry room, and a package and storage room.

The building is in close proximity to Union Square Park, Madison Square Park, and Washington Square Park, as well as amazing restaurants, fitness clubs, gourmet supermarkets such as Eataly, Citarella, and Whole Foods, and a wide variety of fashion shops along Fifth Avenue. Nearby public transportation is abundant as the 4/5/6/L/N/Q/R/ and L lines are all located at Union Square at 14th Street and the 1 train is located just down the street at 18th Street.

I look forward to meeting you and showing you this special home located along the premier Gold Coast stretch of Fifth Avenue.
