When you build a new office building, the typical strategy is to pre-lease a certain portion of it. That is, you sign leases with a tenant or a few tenants so that you know for sure that X% of the building will be occupied upon completion. It’s a way to manage risk. If you don’t do this, then you are said to be building the office building “on spec.”
When you build a new condo building, the typical strategy is to pre-sell a certain portion of it. That is, you sell suites to purchasers based on plan drawings, certain finishes, and a model suite intended to illustrate what that future suite will more or less look like. And the reason this is typical is because most construction lenders will require you to do that.
So when you see office buildings and condo buildings going up, there are usually already tenants and residents who plan to move in or investors who plan to rent out their suite and have generally transferred that risk away from the developer.
Because really the only time that a purchaser or investor wouldn’t close on a condo suite (and walk away from their deposit) is when the market corrects so badly that it actually makes financial sense to do that. That happened in the U.S. in 2008-2009 in a number of markets.
But by contrast, when you’re building a rental apartment building you don’t have anything to pre-sell and your tenants (unlike office tenants) aren’t going to sign leases with you for some space that will be ready in 3 years. If you’re lucky, they might sign a lease with you for an apartment that will be ready in 3 months. This means that by default you are also building “on spec”.
Now rental apartments are often considered to be the safest real estate asset class and the least correlated with the macroeconomy. But as a developer and city builder, this dynamic is still something to keep in mind.


Completed in 1952, the Unité d'habitation in Marseille, France (more specifically known as the Cité radieuse) is one of the most famous buildings by Swiss-French architect, Le Corbusier. Every architecture student learns about it at one point or another.
It’s famous because it was a model for a new way to live and build cities. Le Corbusier envisioned the apartment building as a kind of vertical city. The corridors weren’t thought of or referred to as corridors, they were instead called streets and lined with shops and businesses.
Of course, Le Corbusier later became famous for inspiring an entire generation of buildings that many people now hate. Some believe he was completely misguided and others believe we simply bastardized his intents. But whatever the case may be, he certainly had a profound impact on cities.
So if you happen to be in Marseille between July 4 to 19 (2015), you should check out an installation at the Unité d’habitation called Apartment N°50.
It’s an installation put on by Jean-Marc Drut and Patrick Blauwart. They are the owners of Apartment N°50 and, since 2008, they have invited a designer or studio to come in and renovate it on an annual basis. They then open it up to the public during the summer. I think that’s a really neat idea and would love to visit sometime.

I was browsing through my online reading list this morning (as I do every morning), and I stumbled upon this Dezeen article talking about a big new 6.5 million square foot development being proposed in Miami’s Park West neighborhood.
The goal of the project is to transform Miami into “Florida’s Silicon Valley.”
This sort of thing is happening all around the world. From Buffalo to Lisbon, cities everywhere are betting on tech, startups, and entrepreneurship to grow their economy in the 21st century. And I personally think that’s really exciting.
But as I was reading the article, I couldn’t help but think of an old essay that Paul Graham wrote back in 2006 called, How to be Silicon Valley. (Paul Graham is a famous Silicon Valley entrepreneur/investor).
In his essay Graham argues that to be or to replicate the model of Silicon Valley in your city, you basically need two types of people: rich people and nerds. The idea, of course, being that the nerds work on the cool new ideas and the rich people then fund them.
Using this logic, he specifically calls out Miami as a city where few startups happen and as a city not likely to become another Silicon Valley. Though there’s lots of money and rich people in Miami, there simply aren’t enough nerds. In Graham’s words: “It’s not the kind of place nerds like.”
But that was back in 2006.
The iPhone didn’t even exist yet. Things have since changed. Now there are successful tech companies like Snapchat (valuation north of $15 billion) that are based out of cities like Los Angeles. And I think you could argue that Los Angeles and Miami do share some similarities.
So while it may have seemed far fetched in 2006 for Miami to become a startup hub, is that really the case today?
