With supertall towers popping up along Central Park's southern edge like wildly expensive luxury mushrooms, Manhattan's largest park is about to be cast into shadow—some as long as half a mile. The real estate boom is stirring up a debate: Do we have a "right to light"?
Not in America. But there are plenty of laws in other countries that protect homeowners' right to natural light—most of them stemming from around the time of the labor rights movement at the turn of the century, when dark, dingy tenements across Northern Europe and the US were replaced by neat, orderly public housing.
In Denmark, for example, there's a law that determines exactly how much direct sunlight an apartment must receive—it's even changed the way that many windows are designed. In England, a law called "ancient lights," or "right to light," protects any building that has received natural light for more than 20 years from future developments.

But, in the U.S., things are a bit more shady. A number of court cases here have attempted to block developments based on light, going as far back as 1959, when two Florida hotels duked it out over a bit of blocked sunshine. That case set the precedent for many others: The judge held that there is "no legal right to air and sunlight."
In New York City, we have air rights—a concept that dates back to a law from Roman times: For whoever owns the soil, it is theirs up to Heaven and down to Hell. Modern air rights were spurred by the birth of air travel in the early 20th century, when New York City was the booming skyscraper capital of the world.
Clarification: A previous version of this post poorly explained modern air rights in NYC. The Skyscraper Museum offers up a better description in its 2013 exhibition, SKY HIGH & The Logic of Luxury, in which it explains that modern air rights in NYC emerged in the early 1960s with new zoning laws that regulated building with something called floor area ratio, or FAR—defined as square footage multiplied by a number determined by the zone to which the building belongs—that limits how much structure can be built on a particular lot and encourages developers to create public spaces on the street level. They also allow developers to buy the air rights from nearby buildings and apply them to their own lots, the Museum's director and curator Carol Willis explains in the exhibition's online home:
The formula for FAR and the ability to purchase and pile up additional air rights has created an invisible Monopoly game in Manhattan real estate in which developers often work for years to acquire adjacent properties that could be collected into an "as or right" tall tower.
It's crucial to note, at the Skyscraper Museum does, that the buildings whose FAR has been purchased by a nearby tall building can never be developed higher. Still, the spate of new construction projects along Central Park (what Gothamist calls "Billionaire's Row") has some people arguing for a law that protects the average New Yorker's right to light further. In an op-ed in the New York Times this week, Warren St. John sounds the alarm about the danger of letting towers rise along the park:
New Yorkers who want to protect Central Park will have to do it on their own... And they need to hurry, before the sun sets permanently on a space the park designer Frederick Law Olmsted envisioned as “a democratic development of the highest significance.”
After all, as St. John points out, people who are willing to fight for public spaces are disappearing quickly, while organizations that have traditionally critiqued developers are now run by them.

But will shadows be enough to spur rage amongst New Yorkers? Or will we distract ourselves with pumpkin-flavored treats and complaining about Banksy until, one day, we wake up and realize that the single window in our terrible railroad apartment is blocked by the servant's entrance to a $100 million palace? And besides: Isn't it NYC's prerogative to build higher, faster, and stronger? We've never been a city to turn down new development—we're not Paris.
