Casa Condominio Residenza, or CASA, is a high-rise condominium building at 33 Charles Street East near the intersection of Bloor Street and Yonge Street in downtown Toronto, Ontario, Canada. It features a New Modernist design by architectsAlliance emphasizing glass curtain wall, with balconies wrapped around the building from the podium to the top. An overhanging concrete slab concludes the design at the roof of the final floor. It is lit from underneath at night. The balconies themselves have transparent glazed balustrades, and the podium's main facade facing Charles Street also makes use of glass curtain wall extensively, framed with black brick.
