Alex Bozikovic (architecture critic for the Globe and Mail) is one of the most vocal proponents of more housing and more density within Toronto's low-rise neighborhoods. Last year, he organized an international design competition where he asked firms to come up with innovative, yet sensible, solutions for how this could be done. I'm a little late getting to this, but today I'd like to walk you through this immensely clever solution by Batay-Csorba Architects, called Triplex Duplex.

The project uses two prototypical, but random, semi-detached lots from the Christie & Bloor area of the city. Each one is 18' wide x 100' deep. So your typical long and narrow lots. From the street (see above image), it looks highly contextual. But in plan, you begin to see the 3 main volumes of the project emerge. Here's a ground floor plan from the architect:

Each volume is around 2,500 square feet. I presume that includes the basement. If you exclude the basement area and the vertical voids throughout the project, which you're allowed to do in your calculation of gross floor area in residential zones, I suspect we'd arrive at an FSI (density) number that isn't that much more than what already exist in these sorts of areas.

At the front of the house (right side of the above plan) is a set of stairs (and a patio) leading down to the front basement unit and a set of stairs leading up to the main front unit. An inset patio also forms part of this main entrance (image below), which is a great way of adding outdoor space while at the same time maintaining privacy across the units. These strategy is one of my favorite aspects of the project.

The rear units are similarly accessed at the back of the building. And the two middle units are accessed along the side of the house. All in all, this housing typology has the ability to accommodate up to 6 units: 3 main suites and 3 secondary type suites. By the architect's own estimate, this could result in 147,000 new housing units across the city if every lot occupied by a semi-detached house were to be redeveloped in this way.

But I wonder if any consideration was given to the secondary (basement) suites that may already exist in these zones. Because in some cases, and as beautiful as these homes may be, we may only be talking about 2 additional suites. Triplexes are also already allowed in some areas of the city. So does this ultimately achieve its intended goal, which is the creation of more "missing middle" housing in order to ease overall housing pressures? Or do we need to be thinking bigger?

As a follow-up to this post (subscribe to stay connected), I am going to look at what a development pro forma might look like for a project of this scale. The numbers have a way of answering a lot of questions. That said, kudos to Alex for taking on this initiative and kudos to the design team for a pretty spectacular architectural solution.

Things are busy right now as we get ready to unveil Junction House this fall and so I’m a bit behind on my news and reading. 

I just finished reading Alex Bozikovic’s Globe article on BIG’s new KING Toronto project (official name). It is an interesting piece about creating villages and a sense of community in new developments – something that Bjarke Ingels has been focused on for many years. 

Below are a few renderings of the project. I’m excited for this one. And as I said before on the blog, I am sure it will be precedent setting in a number of ways.

One remark from the article that stood out for me is this one here:

Still: The design breaks a lot of rules. Which is why it took two years of difficult negotiations with city planners to reach approvals. “We wanted it to be quieter,” says Lynda MacDonald, a senior Toronto planner who was involved in overseeing the project. “It’s a very large project, and we wanted to make sure it respected the character of King Street.”

I am often asked why we don’t see more innovation in architecture and real estate. There are a number of reasons for that. One of them is risk. Development is in many ways a game of risk mitigation. 

But another reason is that when you try and do something unconventional that disrupts the status quo, you also call into question the typical planning criteria used to evaluate projects. And that may slow you down.

Alex accurately points out in his article that we are used to doing things around here in one of two ways:

The King Street project is also an ambitious experiment with urban design. There are basically two species of tower in Toronto: a midrise slab of six to 10 storeys, which steps back at the top; and a “tower-and-podium,” a model borrowed from Vancouver that combines a fat, squared-off base (or “podium”) with a tall, skinny residential tower. Both can work, but can also create the big-box blandness that many people dislike about new urban housing.

None of this is to suggest that we should ignore the character of a particular area. It is critical and I believe that KING Toronto has been mindful of that. 

But I also firmly believe in ambitious city building and I think there’s no question that KING Toronto is doing exactly that.

This evening Slate Asset Management hosted the community meeting that I’ve been writing about on the blog over the last little while. 

And at this open house Jeanne Gang of Studio Gang introduced a new block plan and mixed-use building at the southwest corner of Yonge Street and Delisle Avenue in midtown Toronto.

I think it went really well. We had over 200 people RSVP, but based on my imprecise head count, over 300 people actually showed up. 

I would tell you more right now, but it’s very late. So I’m going to instead leave you with this article by Alex Bozikovic, titled, Studio Gang’s new Toronto tower follows the right recipe: tall, innovative and excellent.
