Building Description: AVANT, the region’s first award-winning mixed-use development converted from a former federal office building, contains hotel, retail, office and luxury condominiums within a 16-story, 405,000-square-foot facility. The world-class complex boasts environmentally sustainable design and construction. An elegant and energy efficient glass curtain wall exterior offers occupants all the advantages of abundant natural light while maintaining minimal glare and maximum efficiency standards. Office space on floors 9-12 offer large, efficient floor plates and beautiful views of both the city and Lake Erie. Property amenities include 24-hour security, a state-of-the-art fitness center, full service restaurant, cafe and catering located in Embassy Suites by Hilton, separate entrances and elevators, and valet parking and hotel shuttles for clients and guests.

Construction began on this building in 1969 and was completed in 1971. It was originally constructed as the Thaddeus J. Dulski Federal Building housing 50 federal agencies and workforce of nearly 1,200. The US General Services Administration, which owned and operated the building, determined in the mid-2000s that the property would be too expensive to renovate, and vacated it in 2005. It reopened in 2009 as the The Avant.
