King Portland Centre is in the heart of the King West neighborhood—a prominent cultural and entertainment district in downtown Toronto—with a Victorian commercial building to the east and historic rowhouses to the north. The development’s base podium steps back from the street and features large, bricked arches to frame the ground floor and connect to the district’s brick-and-beam industrial character, while seamlessly integrating a modern curtain wall glazing with curved glass corners for the office tower above.
Tenants enjoy unobstructed views of the city skyline to the south. The interior office spaces feature floor-to-ceiling windows, allowing natural light to pour in and frame stunning vistas of the cityscape, while the curves add a unique detail and visual interest. The building was designed with large open floor plates that are highly adaptable, and with raised-access floors that allow for easy reconfiguration of the mechanical and electrical systems. Green terraces offer outdoor amenity spaces for the office workers, and three levels of underground parking accommodate the needs of the new inhabitants added to the block. In all, the project introduces more than 23,000 square meters of office space and amenities to the site.
The guiding principle of the tower is long-term sustainability and, through an integrated design approach, it achieved its targets. The office portion of the development is LEED Platinum-registered and features photovoltaic (PV) solar panels on the roof. The office tower’s overall energy consumption was designed to be at minimum an 18 percent below ASHRAE 90.1 model building or a 25 percent below MNECB model building. The building meets Toronto Green Standard Tier 1.
