15 William, the 47-story condominium in the Financial District, collaborated with domino magazine on a show house which opened on March 31, 2015 with a cocktail reception in the rooftop penthouse. The “shoppable” show house, a first of its kind, paired four rising-star interior design firms with four high-profile furniture brands to create stylish, modern residences. The shop house will be open to the public through September 15 and featured items in the four residences are available for sale through domino.com.
