The 15-story 1345 S. Wabash building has been a part of one of the most dramatic neighborhood transformations in Chicago. As the city’s South Loop shifted from light manufacturing through widespread vacancy and now to high rise residential, architects have had a chance to imagine a new cityscape. Brininstool + Lynch’s contribution comes in the form of a glass and post-tensioned concrete condominium tower, which echoes Chicago’s modernist past, while looking to contemporary ways of living. Textured board-formed concrete and exposed structure fill loftlike layouts and communal spaces. Private balconies cantilever from each unit, providing views and outdoor space in the densifying neighborhood. The development is a symbol and a standard for the area.
