One of the things that makes cities so exciting is the fact that they’re always changing. New restaurants open up. New buildings are built. Old buildings (with no heritage value, of course) are demolished. Bike lanes are added. New infill homes pop up in quiet residential neighborhoods. And the list goes on.

For years I’ve wanted an app or some sort of product that would allow city builders to keep track of everything that’s going on in their city. In the same way that Foursquare helps you find cool restaurants around you, I would like to know about everything that’s going on, from rezoning applications to construction updates.

One of the challenges, of course, is that I’m sure more people care about cool new restaurants than about esoteric planning applications. It’s definitely a niche market. But that doesn’t mean there isn’t a thriving group of people who do care. So I’ve decided to introduce an Architect This City hashtag on Twitter: #ATHISCITY.

I’ll be using it for city building updates and, if some of you join in as well, I think it could become a great way to keep track all of the neat things that are happening in our city, as well as in others around the world.
