A grand staircase is at the heart of One Hanover, a sweeping renovation spanning over 27,000 square feet in Manhattan's Financial district situated above Harry’s Bar, a Hemingway haunt dating back to 1911. With the setup and amenities of a chic social club, a primary palette of chalky white paint, warm walnut wood, and marble mosaics evoke a sense of serenity in juxtaposition with the building’s colossal scale.
