Seun Sangga is Seoul's first mixed-use complex.

Constructed between 1967 and 1972, the elaborate structure sits atop a strip of land measuring 50 m x 1.2 km, which had been flatted during the Second World War as a way to contain the spread of fire in the event of an air raid and to act as an evacuation corridor.

It's a modernist development that is very much of this period. It's massive, complicated in section and, in many ways, completely disconnected from its surrounding urban context. Flanking the various buildings are elevated and covered walkways.

So it is perhaps not surprising that this development has followed a similar fate to many others of this era. While it was initially viewed as being quite modern and desirable -- it was one of the first buildings in Seoul to have elevators -- Seun Sangga was quick to start showing signs of decline.

In fact, by as early as the 1970s, the complex became known for its porn shops and a bunch of other informal economy-type activities.

It's an interesting, though familiar, story.

I had coffee this morning with an engineer who is going back to business school in order to segue into real estate development. This is a fairly typical journey. Lots of people come into development from a related discipline. In my case, it was architecture (even though I never practiced architecture). It was also the case when I went to Rotman that something like a third of the class had a background in some sort of science or engineering field.

However, one thing I did mention this morning was that he will likely find that he will need to unlearn certain things as he moves forward. Every discipline tends to indoctrinate us with a certain way of thinking about the world. Lawyers tend to be a certain way. Engineers tend to be a certain way. And architects tend to be a certain way.

In my case, I found that architecture school taught me to be, among other things, an intense perfectionist. The modus operandi in design studios is that your project is never ever complete. The more you work on it, the better it will become. And as a result, you should feel a deep onus to work on it as much as humanly possible. But in business, this isn't practical. In the vast majority of cases, speed over perfection will serve you better.

I believe wholeheartedly in multi-disciplinary backgrounds, and maybe this is one of the reasons why. It shows you what you should unlearn. What would you say your biases are?

Construction is generally considered to be the world's largest industry, and yet, it is well known that its productivity levels suck. Over the last half century, the industry has experienced something in between meager and negative productivity growth.

It is for this reason that, for as long as I can remember, people have been trying to figure out how to turn development and construction into something more repeatable and less custom -- something like a product.

Now, there can be a bit of a stigma associated with this moniker. Architects don't often like to think of their work as being a product and references to modularity can sometimes evoke feelings of cheapness (think manufactured homes).

But I think all of this is quickly changing. And at the end of the day, we are going to need to start building like this if we have any hope of making housing more affordable within our cities.

Here's an example.

Back in 2021, I wrote about a new modular housing company called Juno. They had just broken ground on their first project in Austin (a five-story 24-unit building), and they were in the media talking about how they had more or less reduced the building down to 33 standardized parts.

The multi-family space has since softened in Austin, and I don't have any inside knowledge of how this project went, but the building is now complete and being leased up. And regardless, I think it's an important case study to look to. This is where our industry is heading.
