The 90 Elgin Street project features an eight storey pavilion of noble character fronting Elgin Street. Sympathetic in scale and materiality to the context of Confederation Square, this pavilion is visually anchored by means of green pedestrian bridges to a seventeen storey tower. This plan configuration produces facades both abutting and recessed from Slater Street and Albert Street to create a layered composition. In addition to LEED Gold certification, sustainable design principles were fundamental to the design scheme. This building incorporates extensive energy modeling. Materials are natural, robust and thoroughly considered for each application. They include limestone within the building envelope and as a finishing material for floors and walls inside. The finishing of walls, ceiling, millwork and other accent opportunities of interior spaces incorporate reclaimed woods from the national capital region. A mosaic pattern of solids and voids, between opaque metal and transparent glass panels, is a key component of the composition. Through this rich patina, it carries a dialogue with the copper used on buildings surrounding Confederation Square. Vegetated green roofs have been designed at the 2nd and 9th floors. A six storey high exterior vegetated bridge, on the east side of Slater Street courtyard, creates a visual connection with the vegetated green roofs on the 2nd floor and is overseen by the Conference Centre Suite to the 8th floor. At the the north entrance, the lobby accesses a landscaped, naturally illuminated winter garden that includes a two-storey green wall visually linking the lobby with the second floor Conference Centre. This green wall becomes a visible statement of purpose for the introduction of the natural environment on entering and travelling within the building.
