Union League Rooftop Dining

O’Donnell & Naccarato provided structural engineering services for the 9,600 SF rooftop restaurant and 1,400 SF outdoor terrace atop the landmark Union League Annex building, completed in 1911 by renowned architect Horace Trumbauer. The structure, situated on the 15th street side of the rooftop, is designed to largely be invisible from the street and maximize the view of the city.
