Construction cranes dominate the New York City skyline almost as much the city’s tallest spires. A street with scaffolding, especially in Manhattan, is a sight seen more often than not. Thousands of projects are currently underway in the five boroughs and it’s impossible to keep track of them all. To provide some perspective, a new interactive map and database from the New York City Department of Buildings allows you to visualize all the active major construction sites in the city. Updated daily, it unveils the great pace at which the city is changing in real time—not to mention that it shows the disparity in investment from neighborhood to neighborhood.

Categorized by square footage, estimated cost, and number of proposed housing units, the data lets users analyze what’s being built right now and where. According to the site, there are 7,457 active permits filed and 197,913,815 total square feet of construction happening now. Brooklyn and Queens have the most sites under construction with 2,800 projects and 2,500 projects respectively. Nearly 2,000 more new buildings are coming up than renovations.

So this leads us to ask: How is the city making room for all this new space? The answer: It’s building up.

The largest-scale project shown is 500 West 33rd Street (a.k.a. 30 Hudson Yards), a 3.9 million-square-foot, mixed-use skyscraper spearheaded by the Tishman Corporation. It’s subsequently the most expensive project going up in New York at a reported $576.68 million. Norman Foster’s 410 10th Avenue (50 Hudson Yards), an office tower, comes in a close second at 2.91 million square feet but is beat out for second priciest project in construction by the residential conversion happening at One Wall Street.

The data also details that the tallest new building under construction in New York is, not surprisingly, Adrian Smith + Gordon Gill’s Central Park Tower at 225 West 57th Street. The supertall boasts 98 floors and should top out next year. Also hitting the top ten list of tallest buildings by floor count are 220 Central Park South by Robert A.M. Stern, One Manhattan Square by Adamson Associates and Dattner Architects, as well as the MoMA-adjacent 53W53 by Jean Nouvel. The residential project with the most apartments offered under construction is HTO Architects’ 22-44 Jackson Avenue, a controversial two-towered, 1,115-unit development that’s replacing 5Pointz in Long Island City, Queens.

The map also shows the stark differences between the construction corporations leading the market. Tishman currently has so many projects under its purview that together they span a total of around 15 million square feet in New York. Lendlease and Turner fall behind with 5.4 million and 4.8 million square feet, respectively.

According to the data, 120 million square feet of apartment projects are underway, with five of the top ten residential projects with the most dwelling units going up in Queens alone. What this map doesn’t do, however, is zero in on how much residential construction is affordable. To find that out, you have to extrapolate from the data by looking at each project’s permit application on the DOB’s website. Having that information more easily available, maybe also as an interactive map, would be even more helpful to normal New Yorkers than a site that largely details the city’s tallest and most expensive buildings. All you have to do is walk outside and look up to know that.
