As one of the most—if not the most—photographed construction projects in Toronto, the 58-storey L Tower continues to draw our eyes and cameras upwards towards the sweeping sail-like curve which is redefining our east-side skyline. Since the CityzenFernbrook and Castlepoint Numa joint-venture topped off earlier this year, we have paid close attention to the progress of cladding installation, and with much of the main tower structure now fully cladded, we returned to the project last week for an exclusive peek at the ongoing work up top. For the first installment in our trip to the top, we take a look at the louvers now being installed on the southern façade of the tower’s massive mechanical penthouse.

Mechanical floors finish off the top of modern skyscrapers, housing the equipment needed to heat and cool the building’s interior, dampers to reduce sway, machinery to run the elevators, and more. Large scale equipment like boilers and air conditioning units typically requires ventilation, a necessity that can be a challenge to attractively incorporate with the rest of the architecture. The teams at Studio Daniel Libeskind and Page + Steele / IBI Group Architects has met the challenge by designing L Tower’s louvers to closely match the tone of the tower cladding.

While the tone match isn’t 100%, the louvers do manage to blend in pretty impressively with the cladding below. In fact, from street level it is very difficult to even tell that one is looking at metal louvers as opposed to a continuation of the window wall system seen lower down the southern, eastern, and western façades. From close up, however, the slatted steel louvers are much easier to see.

The hidden interior of the louvers has a steel mesh grid secured to it.

In the photo below, we can see a few important items (aside from a dizzying perspective of the rail tracks and Backstage construction site): not only do we get a close up view of the powder-blue louvers, but also top down perspective on the swing stage being used to install the mechanical floor cladding, currently resting on a wooden platform which has been temporarily installed in the building's grand penthouse suite.

Raising and lowering the swing stage relies on a complicated scaffold recently constructed atop the tower’s distinctive tip, something we will look at in our next story, tomorrow.
