My super scientific Twitter balcony survey has revealed that most people seem to like balconies and terraces. Out of the 257 people that voted (not a huge number), 77.4% said that if they were in the market to buy or rent a new place, they would probably want a balcony or terrace. I realize now that my wording could have been more precise. Either way, the results seem to suggest a clear preference.
But there are all sorts of reasons for why you might want to avoid building balconies: energy performance, upfront costs, long-term maintenance, usability at high elevations, overall aesthetics, and so on. In fact, I once had an architect turn down a job because they don’t typically work on residential buildings and, when they do, they refuse to work on ones that have balconies. He told me that they don’t want the liability.
But then what inevitably happens is that the sales and marketing team joins the design meeting and says, “yeah, we hear what you’re saying, but people like outdoor spaces.” And then the great debate starts. Okay, so what percentage of the suites should have an outdoor space? What about a sliding glass well? I think so-and-so is doing it on their project. Yeah, but they’re real expensive and they leak air.
The reality is that there are many buildings without private outdoor spaces and there are many cities where it is common not to build them. Moreover, my Twitter survey doesn’t really tell you exactly how people might behave when they’re about to make a purchasing decision. What you really want are data points and things like A/B tests.
Let’s take for example two typical/identical 600 square foot suites, with the only difference being that one has a balcony and the other doesn’t. Now let’s say that the one with a balcony is selling for $1,400 psf or $840,000 and the one without a balcony is selling for $1,350 psf or $810,000. Will some of the 77.4% that voted balcony/terrace possibly buy the $810,000 suite? Of course. Because it’s less expensive.
So how does one go about making the right decision when it comes to designing for outdoor spaces? Well, in some cases, you won’t have a choice. We have had instances where the City has asked us (okay, forced us) to remove all of the balconies on a particular elevation because they didn’t fit with the urban design aesthetic that they wanted for the streetscape. That always pisses me off.
That aside, my view — and this is just my opinion — is that you can’t generalize when trying to make this decision. You need to carefully consider who your customer is or will be. I’ve written before about the divide between investor demand and end-user demand in residential buildings. It impacts design, and outdoor spaces are no different.
If you take for example Junction House, it is a predominately end-user building. That’s who we thought would be buying and that is who bought. When the team was designing the two-storey House Collection, the intent was to create a kind of substitute for low-rise housing. And so these homes had to have outdoor spaces (they have terraces). This was never a question or a debate.
Similarly, one of the reasons why One Delisle looks the way that it does is because the team set out to create unique terraces, as well as varying outdoor spaces, all throughout the tower. The thinking was, “people like terraces in mid-rise buildings, like Junction House, so let’s figure out how to do that in a high-rise building typology.”
At the same time, we have suites with Juliet balconies at Junction House and it is certainly true that the above recipes may not be suitable for every project. Again, there are lots of buildings without private outdoor spaces, including ones that have sold during this pandemic. One of the things that I have also discovered is that common area outdoor spaces and nearby green spaces can have an impact on whether or not people feel they need private outdoor space.
All of this to say that one size does not fit all. Which is probably why this topic remains such a great debate.
Note: I am making a distinction between balconies and terraces. Balconies typically cantilever out from a building and are not insulated. Terraces, on the other hand, are typically a roof condition in that they sit above a conditioned space. This usually means that the concrete slab will need to get “built up” with insulation and paving. A drainage system will also be required.

Apparently I’ve been living in the dark ages. The One Delisle project team just introduced me to Bluebeam Revu and, frankly, I’m not sure how we were marking up PDF drawings before this. It’s faster and more responsive than Adobe Acrobat. Everyone’s comments sit nicely in the cloud. And you can even take measurements off of the drawings. It kind of feels like a light and friendlier version of AutoCAD (which I haven’t used in over a decade). Marking up drawings is something that I do regularly as part my job. Sometimes I do that with trace paper (I did that for probably every suite at Junction House). But more often it has been with Adobe Acrobat. If you’re in the same boat and aren’t yet using Bluebeam, I would encourage you to check it out.

Back in March of this year, which seems like a very long time ago, I wrote about how One Delisle came to be and how City Planning at the City of Toronto were recommending approval of its development application. Well today I am thrilled to announce that, after two deferrals, these recommendations were adopted (with some amendments) by Toronto and East York Community Council. Though it will still need to go through City Council on July 28, 2020, this milestone is a big deal for the project. It’s now time for the next chapter in this story. So stay tuned. For those of you who are new to One Delisle and would like a bit of background, here is a good place to start.
I have said this before on the blog, but one of my favorite tall buildings is the Mira tower in San Francisco by Tishman Speyer (developer) and Studio Gang (architect). Now that it’s pretty much complete and residents have started to move in, John King, urban design critic for the SF Chronicle, has published this review of the building. It’s behind a paywall, but you should be able to at least see all of the photos, and below is an introductory excerpt.
Even with today’s grim need for social isolation, San Francisco’s most eye-catching residential tower wants to pull you close.
From the Bay Bridge or the Embarcadero, the 39-story Mira at the corner of Folsom and Spear streets is a flowing stack of tightly wound white metal bays, frozen in motion. Fragmentary glimpses from nearby blocks defy expectations, whipsawed slivers amid the stodgy norm.
Finally, there’s the view straight up from the sidewalk — a crisp commotion of stacked angles, precisely arranged but seemingly ready to fly out in a dozen directions at once.
Though Mira has been in the works since 2014, the architectural show still feels fresh as the first residents begin to unpack. But this 392-unit residential complex was also conceived as a celebration of triumphant urbanism — a far cry from the mood of this troubled summer.

Phaidon — publisher of books on art, design, architecture, food, and fashion — has a new publication coming out this summer called, Studio Gang: Architecture. They are describing it as: “An in-depth exploration of one of the most important, innovative, and creative architecture practices working today.” As most of you know, we are working with Studio Gang on an important project in midtown Toronto. And so we are of course thrilled to see the firm’s work being celebrated. To pre-order a copy of the book, click here. They are supposed to start shipping around mid-May.

In the fall of 2016, Lucas Manuel (Partner at Slate) and I traveled to Chicago in order to meet with Jeanne Gang and the rest of the studio. Our objective was simple: We were looking to find an architecture firm that we could partner with and do something very special with at Yonge + St. Clair. We wanted to start from first principles and rethink what a tall building could be in Toronto.
Studio Gang was at the top of our list.
During our meeting and studio tour, Jeanne and her team asked a number of poignant questions about our vision for the area, our goals for the project, and our commitment to sustainable design. So much so that when Lucas and I left the meeting we both looked at each other and said: “That wasn’t us interviewing them. That was them interviewing us.”
It was obvious that they were committed to high quality architecture, environmental sustainability, and overall community building. And it was equally obvious that if we, Slate, weren’t committed to the same, then we weren’t the client and partner for them.
It has turned out to be a great partnership. Over the last three plus years, the team has remained committed to living up to the promises we made to each other in that first meeting in Chicago. And on many occasions, that has meant taking the more difficult path and fighting for what we believe is great design and great city building.
Since 2016, we have held and/or participated in multiple community visioning sessions with Councillor Josh Matlow and key stakeholders from the community. Two pre-application meetings with City Planning. Two big and public community meetings. A design charrette for the Yonge + St. Clair area. And five meetings with a local “community working group” that was formed following the bigger community meetings. Our application was also before the City of Toronto’s Design Review Panel (DRP) at the end of 2018, where it was unanimously supported (though with some constructive feedback).

It has been a long road working to create Studio Gang’s first project in Canada. One that I like to think started in a jazz bar in downtown Chicago (it actually started much earlier). And so I am thrilled to announce that City Planning, City of Toronto, are now recommending approval of One Delisle! Their report is public and the project will be considered by Toronto and East York Community Council this Thursday, March 12, 2020.
If you would like to speak at or submit a comment to Community Council — ideally in support of the project — please email the City Clerk at teycc@toronto.ca. Myself and the team hope to see many of you at City Hall this Thursday morning at 10:00AM.
For those of you who aren’t familiar with the project, here is a summary from City Planning:
This application proposes to amend the Official Plan and Zoning By-law to permit a 44-storey (143 metres plus a 7-metre mechanical penthouse) mixed use building with 293 dwelling units and 159 parking spaces within a 4-level below ground garage at 1-11 Delisle Avenue and 1496-1510 Yonge Street. A 2,506 square metre public park will be secured off-site on the rear portions of 30 and 40 St. Clair Avenue West. The Official Plan Amendment also redesignates a portion of the subject site from Apartment Neighbourhoods to Mixed Use Areas.
The proposed development is consistent with the Provincial Policy Statement (2014), conforms with the Growth Plan for the Greater Golden Horseshoe (2019), conforms with the applicable policies of the Official Plan and the Yonge-St. Clair Secondary Plan, and is consistent with the Yonge-St. Clair Planning Framework and Tall Building Guidelines. The proposal also meets a number of significant public realm and built form objectives, some of which are outlined in the Yonge-St. Clair Planning Framework, including: securing a 2,506 square metre public park in close proximity to the Yonge-St. Clair intersection; wider sidewalks along both Yonge Street and Delisle Avenue; enhanced street landscaping; restoration and relocation of an existing Art Deco façade; a pedestrian scale base building in keeping with the main street character of Yonge Street; a north/south midblock connection between St. Clair Avenue West and Delisle Avenue; high quality architecture; and consolidated access and servicing for the block.
This report reviews and recommends approval of the application to amend the Official Plan and Zoning By-law.

Architect Jeanne Gang (of Studio Gang) has just been named to the TIME 100, which is Time magazine’s annual list of the world’s most influential people. Jeanne is the only architect to be included in the 2019 list.
Jeanne was named to the “Titans” category, which typically honors those who are at the top of their respective field. She sits alongside Mark Zuckerberg, Tiger Woods, and LeBron James in this year’s TIME 100.
Past honorees within the architecture profession include Elizabeth Diller, David Adjaye, and Bjarke Ingels. All, stars.
The list is in its 16th year. But it’ll be the first year where there will also be a day-long conference. (Lynne and Marc Benioff, of Salesforce, acquired the magazine in 2018 for $190 million in cash and are making some changes.)
Congratulations Jeanne.
Full disclosure: Studio Gang is the design architect for our One Delisle project in midtown Toronto.
The MIRA Tower in San Francisco is one of my favorite buildings by Studio Gang and probably my favorite tall building under construction right now. Here’s a video and a few photos from the San Francisco Chronicle’s urban design critic, John King:
When we first met Studio Gang, this project hadn’t yet started construction. They broke ground in April 2017. But it was one of the designs that got us particularly excited about what a Studio Gang building could mean for midtown Toronto.
Now that the MIRA Tower is well underway, I have to say that it looks even better than it did pinned to the walls of their Chicago studio. I can’t wait to see it in person once it’s complete.
