The United Building is the tallest architectural heritage retention development in North America. In addition to  restoring the exterior of the existing building, Davpart will complete the interior to the highest standard of contemporary office and retail available today, so their current uses can continue. Located on the northeast corner of University Avenue and Dundas Street West, the UNITED BUILDING will evolve to a 55-storey high rise which will highlight the restored heritage structure of the storied Maclean Publishing Company/Maclean-Hunter Building at 481 University Avenue, with commercial and retail space from the ground floor to the 10th floor and new residences above the historic structure.
