A friend of mine circulated this tweet storm over the weekend. It is an explanation of how NYC's housing market works using the example of oranges. The author ends by saying that, "it is a parody and an exaggeration, but I promise you it's not much of one."

The crux of this story about oranges is that if you don't deliver enough to meet market demand, you're going to invariably run into a problem of affordability. If people really want oranges, they are going to bid up the price of whatever oranges they can get their hands on. The same is true for housing.

But there are, of course, some obvious differences between homes and oranges. People don't live in oranges. And I would imagine that there are other ways to get your daily recommended intake of vitamin C.

As far as I know, people also don't buy oranges with the hope that they can derive a rental income stream and/or that they will be worth more tomorrow. And so I'm sure that many of you will be quick to point out that it is perhaps the speculative nature of housing that makes it different from most oranges.

Still, there's no denying that, in most cities around the world, we do a lot to make it exceedingly difficult to build new housing. We constrain supply -- such that we perpetually underserve the market -- and then we wonder why prices continue to rise.

Disagree with this take? Let me know in the comment section below.

I learned this morning that + POOL (pictured above) recently received an official" confirmation to proceed with due diligence." This is after more than a decade of planning, fundraising, negotiations, prototyping and, I'm sure, a bunch of other stuff. City building takes a long time. I'm not exactly sure where this milestone sits in the full spectrum of idea to realization, but it certainly sounds like meaningful progress.

The idea behind + POOL is pretty simple: People like to swim in water. But the East River is dirty and not the best place to swim (supposedly it's been this way -- unswimmable -- since the 1930s). So why not create a dedicated swimming pool in the river and why not make it so that it filters the dirty East River water at the same time. Pretty clever. (The plus sign format is so that it can be split up into four separate uses.)

New York City is in the midst of creating some incredibly unique public spaces. The other big news is that Little Island opened up this past weekend within the larger Hudson River Park. Also more than a decade in the making, the free 2.4 acre public park, which was designed by Thomas Heatherwick, is the result of a $260 million donation from Barry Diller and Diane von Furstenberg.

Start with an idea. Put some money around it. And then fight like hell for many years. That's how these remarkable urban spaces are getting created. This is also pretty much how real estate development works.

Back in 2008, Dasha Zhukova and Roman Abramovich hired starchitect Rem Koolhaas and founded a new contemporary art museum in Moscow called the Garage Museum. Supposedly this was the first philanthropic institution in Russia dedicated solely to contemporary art. (Here's a short video in case you're curious what it looks like.) After it opened, the founders apparently had a realization about the way people like to consume art. Yes, people like to look at art and ponder deep things. But it turns out that people also like just being around art and other art-like things. People started coming to the Garage Museum not only to view the various exhibitions, but also to just hang out.

This insight is now being used to inform a new real estate development company, also by Dasha, called Ray. The mission of the company is to create "architecturally-inspired homes at the intersection of art, culture, and community." Their first two projects are in Harlem and Fishtown, Philadelphia, but apparently they have something cooking in Miami as well. What Ray hopes to do is integrate art and culture in a more meaningful way through cultural programming, exhibitions in their buildings, artist studio spaces, and other creative ideas.

There's also an affordable housing angle. According to the WSJ, Ray's Harlem project is a joint venture with L+M Development Partners. I don't know any of the specifics of this deal, but I know L+M, because one of their founding partners, Ron Moelis, was a professor of mine in graduate school. L+M is focused on affordable and mixed-income housing and uses tools like the Low-Income Housing Tax Credit (LIHTC) to make these sorts of projects financially feasible. They aren't, otherwise. I learned all about them in school and I always found it to be a great way to get the private sector building affordable housing.

"Art and culture, community, and accessible pricing."
