This week, Alex Bozikovic (of the Globe and Mail) dropped the news that a new supertall by Herzog & de Meuron is being planned for the northwest corner of Bay and Bloor here in Toronto. The developers are Kroonenberg Group and ProWinko, both of which are based / have their roots in the Netherlands. At 87 storeys and 324 meters, it would be the tallest building in Canada if it were built today. The proposal includes retail, office, and residential uses.
The first thing that everybody is talking about is the tower's slenderness ratio (the upper floors are said to be about 7,300 square feet). I'm not a structural engineer, but the structural engineers that I do know are telling me that this tower will almost certainly require a tuned mass damper at the top of the building for lateral stiffness. The tower is very narrow in its east-west direction (see below) and so it will perform as a kind of "sail" in the wind. But as New York and other cities have shown us, this can be done.

Another feature of this building is its double skin facade. As far as I know, this would be the first residential building in Toronto to have one (please correct me if I'm wrong). In fact, the only building that I can think of off the top of my head is the Donnelly Centre for Cellular and Biomolecular Research, University of Toronto by Behnisch Architekten and architectsAlliance. (For the record, and as far as I know, I am not related to the donor for this building -- but what a great last name.)
Usually the idea behind a double skin facade is to create an air cavity between both skins and then ventilate it. To reduce cooling loads in the summer, shading devices are also usually added within this air cavity. The system works by trapping and then extracting solar heat gain before it reaches the inside of the building. Engineers and real architects tell me that this generally works a lot better than a typical interior blind, because at that point you've already let a lot of the heat inside of your conditioned space.
I am a big fan of ambition. And this project is certainly ambitious. For more about the proposal, check out the Globe and Mail.
Update: This project is being done in collaboration with Quadrangle Architects of Toronto.

Alex Bozikovic's review of the book Canadian Modern Architecture: 1967 to the Present raises something potentially troubling. Here's what I'm talking about:
It is by turns an exhilarating and depressing narrative: Canada, in this book, appears as a country that announced itself on the world stage in the 1960s and 1970s with incredible ambition but, since then, has retreated toward the mean.
It is potentially troubling not only because I believe in the value of good design, but because I believe that architecture embodies the ethos and cultural context in which it was created.
And so if you believe that our architectural ambitions have retreated toward mediocrity, you might also surmise that our overall level of ambition has retreated toward the same.
That should be viewed as a serious problem.

As I was going through this Twitter thread by Alex Bozikovic on the "Château Laurier battle," I came across a great line by Robert Wright: "We cannot recreate the past only parody it." I told him I was going to steal it, but here I am giving him credit.
The controversy in Ottawa stems from the fact that a number of people believe that a modern addition to the Fairmont Château Laurier (which was constructed between 1909 and 1912) amounts to heresy.
Instead, the addition should be designed to match the "Château style" that already exists. There should be no change. As Alex put it, "people want Disneyland."
We've had this very same debate come up on some of our projects, where people -- but notably, not the city -- have asked us to replicate something that was constructed in the 1800's using labor and material techniques that no longer exist.
This is where Robert's line comes in.
Architecture is a reflection of the cultural milieu in which it was designed and built, which is one of the reasons why we sometimes preserve old buildings. They communicate to us a particular moment in time.
The reason architects, designers, and planners so often respond -- negatively that is -- to Disneyland-type architecture, is that it lacks that same authenticity. It's only a simulacra.
It's for this reason that one of Ontario's "eight guiding principles in the conservation of built heritage properties" is, in fact, legibility:
"New work should be distinguishable from old. Buildings or structures should be recognized as products of their own time, and new additions should not blur the distinction between old and new."
This is not to say that we shouldn't be respectful of the past. Five of the eight guiding principles include the word "respect" in the title. There should be lots of that.
But we would be fooling, and cheating, ourselves if we believed we could mimic the past with any justice. We cannot recreate the past only parody it.
