Yet More on Short Buildings

I’m just playing around here, but here’s a bit more data on building height in response to my earlier question about why all buildings in a neighborhood aren’t the same height (i.e., whatever height delivers the highest profits). First off, there’s an incentive to build high because people will pay more for offices and condos on upper stories. In New York, however, that height premium has been declining:

Interesting! Nonetheless, no matter what city you’re in, it’s still generally more profitable to build higher since the price per square foot goes down. Here is Dean Dalvit:

For the most common office building size, two to four stories tall, the range is from just over $140 per square foot in Winston-Salem to over $240 per square foot in New York….By taking advantage of savings provided by vertical construction, you will see approximately a 4% savings in cost per square foot by increasing the stories to between five and ten stories….For buildings between eleven and twenty stories tall, there is approximately an 11% savings over the mid rise buildings and 15% over low rise….Over twenty stories starts getting into more unique building characteristics that will drive costs in various ways.

Speaking broadly, then, if a particular neighborhood can support a 20-story building, you’d expect to see a lot of 20-story buildings. But there’s also this:

In other words, a 20-story building might be the most profitable, but if you only have enough money to build a five-story building, you might go ahead and do that instead of spending time trying to scare up more financing. It’s still profitable, after all.

Beyond this, of course, there are lots of land use restrictions that change over time and can impact building height. The most famous, perhaps, is New York City’s air rights regulation, which limits total building height in an area but allows developers to swap air rights. It’s sort of cap-and-trade for building height. This means that in a neighborhood with, say, a 60-story cap, it might make sense to build a 40-story building and then sell your unused air rights to someone else who wants to build an 80-story building. There’s lots of stuff like that around.

This is just more food for thought, not any kind of final say on this. If you enjoy falling down internet rabbit holes, you might want to try looking into urban design. I do this periodically, and there is no deeper rabbit hole around.

SIX TRUTHS

Reclaiming power from those who abuse it often starts with telling the truth. And in "This Is How Authoritarians Get Defeated," MoJo's Monika Bauerlein unpacks six truths to remember during the homestretch of an election where democracy, truth, and decency are on the line.

Truth #1: The chaos is the point.

Truth #2: Team Reality is bigger than it seems.

Truth #3: Facebook owns this.

Truth #4: When we go to work, we're in the fight.

Truth #5: It's about minority rule.

Truth #6: The only thing that can save us is…us.

Please take a moment to see how all these truths add up, because what happens in the weeks and months ahead will reverberate for at least a generation and we better be prepared.

And if you think journalism like Mother Jones'—that calls it like it is, that will never acquiesce to power, that looks where others don't—can help guide us through this historic, high-stakes moment, and you're able to right now, please help us reach our $350,000 goal by October 31 with a donation today. It's all hands on deck for democracy.
