Parasitic CN Tower

CN Tower with wood modules

From trading outpost to provincial capital to “Toronto the Good” to the tech and entertainment capital it has become today, Toronto has had many identities, each adapted to suit the needs of that given era. Our plan to add Metsa Wood residences to the CN tower follows in this tradition of reinvention and exploration. But it also explores the methods design may need to employ in order to meet rising demand for land.

The benefits of wood construction are integral to this concept. The lightness of the material allows for the construction of the units between the wind-shielding “wings” of the tower. Its strength and versatility allows for livable and malleable designs that can accommodate the contemporary condo dweller. Supports drilled into the tower’s structure allows for the hanging of livable pods that taper as the original building narrows. These mounting brackets on the tower’s face will be allow the pods to be dropped into place. Connections will be comprised of hidden plates inside the wood kerto elements.

Interiors of proposed wood modules attached to the CN tower

The total cantilever length of the modules is controlled by capacity to attach to tower – our ambition would be to maximize spans. Each ‘container’ has a floor and a roof, with self-contained trusses in the side walls. These side wall trusses have space for insulation and will be concealed on the interior by another kerto finishing panel. Kerto solid panels at exterior provide stiffness and is used to mount cladding or sound insulation between units.

Finally, the open end wall of these containers, all glazed, will need two side posts and a top beam to stiffen the end of the ‘box’ shape. Some lab testing with new connection types might allow us to avoid the posts and beam resulting in floor to ceiling, wall to wall, glass – a view that might not be for the faint of heart!

The modular character of these pods allows for a variety of unit layouts that can accommodate multiple lifestyles and personal choices. As wind is a major challenge building this high up, each of these pods is configured vertically to reduce the protrusion of their floor plates. In turn, this creates dynamic shapes with staircases creating sharp diagonal incisions in otherwise cube-like structures. These pods afford phenomenal views, with other units framing spectacular views of the city.

This proposed design also includes the unique carbon sequestering properties of wood construction – it is a sustainable and conscientious idea with minimal impact. Furthermore, the design’s versatility leaves open the potential to propose similar projects on other largescale freestanding developments globally, increasing the value they bring to their home cities and environments.

For many years the CN tower was the tallest structure in the world, a global icon of height and progress. This time has passed, with the world’s next proposed tallest tower doubling its height. Our proposal reinvents an icon losing its iconic status, demonstrating how its identity can change along with its host city.
