The Duncan, located in Chicago's West Loop, spans nearly an entire city block and combines the best of apartment living with rich amenities, including a full fitness center with an indoor pool and spa, a lobby serving as a co-working space with an attached coffee shop and bar, as well as three roof terraces for warm-weather fun. Founded as the Near West Side YMCA, one of the contributing buildings is named ""Duncan Hall which was dedicated to philanthropist Joseph Duncan who made his fortune inventing an addressing machine in 1893. He and his wife were major benefactors of the YMCA, creating a summer camp for boys near Round Lake, Illinois. As the Duncan was built originally as a YMCA/YWCA, an original basketball court, brick exterior, and preserved architectural details make the Duncan a genuinely authentic home.
