4050 Yonge is a modern office building located in Toronto’s “Hoggs Hollow” district, situated at the northwest corner of Yonge Street and Wilson Avenue. This new mixed-use complex  integrates office condominiums with a four-star hotel. Specifically the site, a former commuter parking lot, is enveloped in nature, with mature hardwood forests on its northern and western edges, including a small, active run-off creek. Northwest of the site can be found the manicured grounds of the Don Valley Golf Course, an equally natural, beautiful landscape.

The concept for this mixed-use project was twofold: to clearly articulate all of the building’s separate programmatic parts (office condominiums, hotel, retail and entrances) and to express the building in an architectural language inspired by nature.

As such, the façade of the nine-storey hotel was configured with vertical, bent bands made from silver prefinished metal (spandrel panels) and fritted glass, that are a nod to the verticality of the surrounding trees. To carry this concept further, maple trees have been planted on the rooftop terraces, at the hotel’s outer edge, capping the building with foliage year-round.

To clearly demarcate the hotel’s main entrance, a large vertical sign has been added to the façade (hotel operator to be determined) along with a horizontal two-storey window cut from the hotel’s vertical tree-like texture.

East of the hotel, the seven-storey office condominium façade is expressed with vertical maple wood battens set between the glass, starting at chair rail height and running below the slab, to control solar glare on every floor. By way of contrast, the office building has a horizontality to its façades that is readily distinguishable from the adjacent hotel.

On its east façade, a vertical glass tower composed entirely of vertical maple wood battens set between the glass, signals the entrance to the office condominiums and the below grade TTC entrance.

Horizontally separating the hotel and office programs from the street level retail is an organically shaped canopy, whose outer edges bend up, like a curled leaf. Cladding its underside is tonge and groove composite wood decking, giving this sheltered pedestrian space an unusually warm, natural feeling.

In its completed form, this mixed-use project presents a collage of architectural languages all of which are inspired by nature, strategically bound together by common materials and tailor made for this urban corner lot.
