Brookfield Office Properties
East Tower, 153,166 m² (1,648,665 ft²) at 51 storeys; West Tower, 85,100 m² (916,009 ft²) at 41 storeys. Linking the two towers is a large Winter Garden, 2,600 m² (27,986 ft²).
Calgary’s two Sixth Avenue office towers will soon tower over most of their neighbours. The 42-storey West Tower joins the phase 1 57-storey East Tower, set to be Calgary’s tallest office building and second only to Toronto’s First Canadian Place in all of Canada.
The two towers will be connected via ground floor and mezzanine space contained in a 63-foot-high Winter Garden Pavilion. This jewel-box-like structure will take on the appearance of a glass box softened by rounded corners and edges. Mullion sections measuring 13 inches by 3 inches will support the Pavilion’s glass envelope.
The development will connect to neighbouring buildings via Calgary’s +15 pedestrian walkway. Both the ground floor and +15 levels will feature lobby and retail space.
The two towers will contain reinforced concrete cores with structural steel floor framing and exterior columns. The below grade structure consists of reinforced concrete columns, slab and wall construction. Crews will demolish sections of underground parking nearby to accommodate the East Tower’s footprint and five storey basement, a hole that will take five months to excavate. Developing back up to grade will take six to seven months.
