The Opportunity
At the iconic intersection of University Avenue and Dundas Street, a storied address is reborn. Originally constructed in 1910 as the Maclean Publishing headquarters, The United Bldg. has been meticulously reimagined as a 54-storey, mixed-use tower that fuses timeless architectural character with contemporary innovation.
This transformative development preserves and elevates the building’s original neoclassical façade while introducing 250,000 square feet of premium commercial space across 9 dedicated office and retail floors.
