Vishaan Chakrabarti is an architect based in New York City. He is the founder of Practice for Architecture and Urbanism (PAU) and the author of two books.

His first book, published in 2013, was A Country of Cities: A Manifesto for an Urban America. And as the title suggests, it was about the virtues of dense urban agglomerations. You know, the kind of cities that I like and have good bike lanes.

His second book, which just came out, is called The Architecture of Urbanity: Designing for Nature, Culture, and Joy. In this one, he talks about the role of architecture and urbanism in fighting both climate change and social division.

Below is an excerpt from a recent interview in Bloomberg where he discusses the book's theme of "social friction." This snippet is also a timely follow-up to yesterday's post about autonomous vehicles:

Cars are problematic when it comes to connective design. It doesn’t matter if they’re electric because the problem with a car is it’s a divider. It’s a metal bubble and it keeps you from interacting with your neighbors. So the virtues of mass transit, public parks and well-designed buildings in cities are not just that they are good for the climate. They are also good for this sense of social coherence. If we’re going to live up to our promise as a country — a multicultural democracy — we need to have spaces that both reflect and perpetuate that.

I haven't read the book yet, but it sounds like it's in the wheelhouse of this blog. If you'd like to, here's a link.

It is surprisingly difficult to find good real estate and development information about a market that you're not familiar with. So I was pretty excited when I came across this map of every development project in Grand Paris (Greater Paris) created by Arthur Weidmann.

It's in Google My Maps and what he has done is pin every project according to status: under construction, under renovation, approved, proposed, and recently delivered. For each pin, you'll also find information like the expected completion date, the use(s), the area, the architect(s), and photos. It is unbelievably detailed and, according to Google, it was last updated 8 hours ago.

Here's the full map with all statuses shown:

And here's what it looks like if you filter by only projects under construction:

It's interesting, but not surprising, to note that the majority of construction projects seem to be taking place outside the boundaries of Paris proper. However, if you alternate to projects under renovation, it more or less flips, with most of the projects being within Paris:

This tells you something about the city.

Sometimes when I'm looking at or for information like this, I think to myself that I must be in the minority of people who are interested in tracking development projects with this level of detail. So I find it interesting that this map has been viewed nearly 300,000 times. Clearly, I'm not actually alone.

The City of Toronto is proposing to turn Dupont Street -- between Dundas Street West and Davenport Road -- into a "complete street."

Here's the area in question:

It's 4.7 kilometers long.

And here's how the city thinks about complete streets:

“Complete streets” are streets that are designed to be safe for all users: people who walk, bicycle, take transit or drive, and people of varying ages and levels of ability. They also consider other uses like sidewalk cafés, street furniture, street trees, utilities, and stormwater management.

Right now, the city is in the public consultation phase. If you'd like to provide your feedback, you can do that here. You have until October 30th. The online tool is also pretty neat. You can drop comments on specific areas of the street. And already the map has been totally filled up.

This is an important and busy artery in midtown. I use it all the time as a pedestrian, cyclist, and driver. It's not the best street, though. Yesterday it took me 45 minutes to drive from one end of it to the other. Along with better street design, this part of the city could use better transit.

I'm looking forward to seeing how Dupont ultimately gets designed.
