Brandon Donnelly — Daily insights for city builders. Published since 2013 by Toronto-based real estate developer Brandon Donnelly. — Page 1467

As an architecture and city lover, it’ll probably surprise you that I’ve never been to Chicago. I think it may have to do with the fact that it has always felt like a sister to Toronto–another Great Lakes city of comparable size. And when you travel, you often want something novel.

But that’s no excuse. 

Thankfully I’m happy to report that last week I booked a trip to Chicago for this August. I’ll be there for an extended long weekend. But since it’s for a bachelor party, it remains to be seen how much archi-touring I’ll actually get a chance to do.

Chicago is a hugely important city in the world of architecture and city building. From Frank Lloyd Wright to Mies van der Rohe to Louis Sullivan , the city has deep architectural roots.

When most people think of skyscrapers they think of New York. But in actuality, if there’s one city that gave birth to the modern skyscraper I would argue that it was Chicago. And it was made possible by the steel industry.

Before the late 19th century, tall buildings were largely built with their exterior walls supporting most of the loads. This meant that the taller you went, the thicker the walls had to be near the bottom of the building. This is why older buildings often feel so heavy and permanent.

But when structural steel became widely available, a new building form was created. All of a sudden architects and builders could create relatively light weight structural steel frames to support the building. The skin, or outside of the building, was no longer carrying the weight.

That made images like this possible:

For most of us today, this building under construction looks fairly typical. First the structure goes up and then it gets clad with its window and exterior skin. But at the time, this sort of construction technique–with the 3rd and 4th floors still unenclosed and the upper floors finished–would have blown people’s minds. It was an entirely new way of building.

Steel framed buildings removed the technical limitations of building tall and also opened up entirely new possibilities for architectural expression–such as the all glass building. Today, there’s a lot of criticism around our glass buildings. But it’s interesting to note that it started as the futuristic dream of architects.

Freed from the technical limitations of load-bearing exterior walls, architects such as Mies van der Rohe began dreaming of transparent, all glass buildings. For them it represented modernity. It was the future. Above is an early charcoal sketch of that dream by Mies.

But our fixation with glass and transparency has never been because of environmental efficiency. It was about light, transparency and feelings of modernity. So as sustainability becomes increasingly critical, we should remember that there’s still lots of innovating left for us to do.

Art and architecture has always been a representation of the time and era in which it was created–which is one of the reasons I’m so interested in technology today. It’s our era. It’s our “structural steel”. And it’s going to impact our cities.

When posterity looks back on us and what we’ve done, I’m sure that will be clear.

Toronto Life recently published an interesting article called Stuck in Condoland.  A lot of people have mentioned it to me, so there seems to be a lot of interest in the topic. It basically profiles the lives of a few young families who live downtown and are trying to raise young children in relatively small condos (think 700 square feet).

I thought it was interesting because I like the idea of small and efficient living. The average post-war bungalow in Toronto was probably less than 1,000 square feet. And so this modern notion that you need a big house in order to properly raise a family is a relatively recent phenomenon. Although we’re a richer city today and that’s what happens when people become wealthier: they consume more.

But the article also makes it seem that developers only want to build small condos and that larger condos and single-family homes just aren’t profitable enough. Thus the reason all these families are being forced to into tiny shoeboxes in the sky. But that’s not really true.

Look, just like every other for-profit business on the planet, developers are concerned with making money. And so they will always look for ways to increase efficiency, drive down costs, and so on. But there are certain realities of the market that developers don’t have control over.

First, developers aren’t building new single family homes in the city (at any sort of meaningful scale) because there’s no land to do so. And because the land use policies in place and the current thinking around how we can more sustainably build our cities for the future dictate that we should be building more intensely. In other words, building up. So it’s not a question of developers not wanting to build single family homes; it’s a question of not being able to.

Second, trust me when I say that if the market wanted large 3 bedroom family units, developers would build them. Mandating them is a useless exercise if people don’t want them or are unable to afford them.

The challenge we face is that a reinforced concrete condo tower is more expensive to build than a wood-framed single family house. So until land values get to a point where single family homes become the more expensive option (compared to condos), I don’t think we’ll see a huge rush towards 3+ bedroom suites.

This is my hypothesis at least. Because when you buy house, you’re really buying two things: the house itself and the land. If the house itself (wood) is cheaper to build on a per square foot basis than a condo (concrete), then the variable that will make a difference is the land. And as people like to say: “buy land, they ain’t making any more of it.”

So what I’m saying is that I just don’t think the situation is as simple as: “developers are bad, all they want to do is build tiny condos and make lots of money.” It’s more complicated than that. But I do believe the question of how families are going to live in the city is an important one.

Today was my MBA convocation at the University of Toronto’s Rotman School . Though I actually finished my degree last year (with a bit of fast-tracking), I had to wait until today in order to formally graduate with the rest of my cohort. I did what’s called the 3-year morning MBA. What that means is that I took most of my classes at 7am.

The picture above is from our weekend retreat right before we started the program (I’m in the back row in the middle). It was taken in the summer of 2011. That feels like eons ago. It has been a tough slog.

So today I’m taking the day off from writing about cities. Instead, I’m just going to enjoy the day off and the closing of this chapter in my life. An MBA is something I had been planning on doing even while I was in architecture school–so it’s nice to be able to check it off. But as I told my parents today after convocation: you ain’t seen nothing yet.
