Description
This high-floor mint-condition 1-bedroom (oversized at 812 sq. ft.) at 15 William Street offers excellent light, an architecturally interesting view, and high ceilings (98), as well as beautiful finishes throughout.
An open kitchen with high-end appliances flows into a bright east-facing living room with a full wall of oversized windows, creating a spacious entertaining area with a view of iconic downtown architecture. Within the master suite, a huge and luxurious master bath offers a stand-up rain shower, custom oversized soaking tub, a large walk-in closet, and louvered doors that open or close off the bath to the master bedroom.
This sleek, modern, and well-designed home also includes a custom (and concealable) built-in office, climate control including year-round central A/C and heat, hardwood floors, and a washer/dryer.
Created by Andre Balazs and Tsao & McKown Architects, this luxury condominium building offers extraordinary amenities and services: 24-hour doorman and concierge; indoor 50 heated salt-water lap pool; fully equipped indoor/outdoor fitness center (including basketball and squash courts as well as a yoga studio); terraced hot tub with outdoor shower, sauna, and steam rooms; and screening room with wet bar.
Perfectly located in the heart of the Financial District, 15 William Street is surrounded by excellent shopping, dining, and transportation.
Unlike the sponsor units available through the sales office, this apartment is a resale, and so the transfer taxes of 1.825% are paid by the seller -- approximately $18,000 in savings for the buyer.
