Key takeaways:
- What people call a “brownstone” is usually a brick townhouse clad in brownstone sandstone, much of it quarried in Portland, CT and shipped to NYC in the 19th century.
- Brownstone material became popular in the mid-1800s as steam-powered tools made cutting the stone faster and cheaper, and its warm, organic look fit the era’s Romantic Classicism taste.
- Brownstones are known for their stoops, carved details, and elevated entrances: elements that became synonymous with stylish urban living in NYC.
- The Portland Quarry closed permanently in 2012, and with limited genuine brownstone material and protected historic neighborhoods, demand far outstrips supply, boosting their prestige and prices.
- Features like stoops weren’t just aesthetic — they originally helped keep residents above street-level manure and grime from horse-drawn carriages.
How did NYC fall in love with the brownstone, anyway? For New Yorkers, few things evoke the dream of upward mobility quite like the brownstone townhouse. With a rich chocolate-brown hue and stately design, this coveted type of townhouse sits several feet above the street, atop staircases with regal banisters. Elegant carvings adorn their doorway trims, like acanthus leaf brackets depicting plants, flowers, or nature run amok. Brownstones tend to be very expensive, or occasionally just regular expensive.
So what is a brownstone, what are they made of, and how did they become the favorite dwelling of so many New Yorkers? Here’s a bit of NYC brownstone history for you.
What are NYC brownstones made of?
Let’s start by clearing up a common misconception: only a small part of a brownstone townhouse or rowhouse is composed of actual brownstone material.
What most people call a “brownstone” is a brick townhouse with an added veneer of brownstone. That’s because as a building material, brownstone is unreliable: it’s soft, close-grained, and prone to cracking and crumbling. Brownstones give off an idea of permanence — even though they’re anything but.

Brownstone is a type of sandstone that dates back to the Triassic-Jurassic period. When first cut, the stone is pink, but deepens into its classic brown hue once it’s been exposed to the elements. Like many works of art, brownstone facades often need to be restored after years of weathering and exposure.
Believe it or not, the majority of New York City’s brownstone came from the same place: the Portland Brownstone Quarry, formerly located in Portland, Connecticut. In the 19th century when brownstone first caught on as a building material, the stone was cut in Connecticut, placed on barges and hauled over to the city, where it was unloaded into stone storage yards along the Hudson and East Rivers.

Why brownstones became popular in NYC
So how did we get here? Time for another quick NYC brownstone history lesson.
By the mid-19th century when some of the first rowhouses were being built, Americans were pretty obsessed with the ideals of Romantic Classicism, specifically its adoration of nature. The Industrial Revolution had by then ushered in a widespread streamlining of production — many new buildings were constructed, and fast. Romantic Classicism was a response to the pace of urbanization, a reminder that nature was not only necessary, but desirable.

Brownstones were the happy marriage of these two worlds. Steam-powered machines let laborers cut and shape brownstone material faster and more cheaply than ever before, making it affordable — and its organic hues recalled the beauty and power of the wild.
For middle-class townhouse and rowhouse owners who wanted a taste of luxury, a brownstone was the way to go. For little money — far less than what it might cost with limestone, granite, or marble — a homeowner could have a six-inch brownstone façade built complete with a stoop, a rising staircase, and whatever lovely carved accoutrements they desired.
Ever wonder why brownstones have stoops? Originally, it wasn’t for people-watching or sunbathing. It was to avoid the manure from carriage horses that littered 18th-century NYC streets. In other words, those elegant stairs were just a way to rise above the muck.

How brownstones came to symbolize wealth in NYC
If brownstone material became popular in part because it was cheap and easy to work with, how did the material grow to symbolize wealth? And how did it get so expensive?
That’s an easy one: scarcity breeds interest.

After 300 years in operation, the Portland Brownstone Quarry closed down for good in 2012. Though there are other places around the world where brownstone is quarried, experts say there’s nothing quite like the stone that came from Portland.
But it’s not just the material that’s become scarce — it’s the style itself. There are only so many NYC neighborhoods with genuine brownstones — the Upper West Side, Fort Greene, Park Slope, and Carroll Gardens, to name a few. And since the building of new brownstones is a near impossibility given the dearth of materials, demand has exceeded supply.

…But not everyone loves brownstones
If you’re in the seeming minority of New Yorkers who don’t care for brownstones, know that you’re not alone.
Edith Wharton, the brilliant writer and master of the NYC upper-class takedown, lived in brownstones all her life and hated the ordinariness of the material, and the way rowhouses repeated themselves ad nauseam down every block. In fact, Wharton said that brownstones made New York “hide-bound in its deadly uniformity of mean ugliness.”
