If you’re drawn to New York’s older, prewar buildings, you’re probably a fan of the classic six. These are apartments with decorative details, high ceilings, and plaster moldings—and as the name suggests, a layout with six, separate rooms. 

A classic six also has coveted features like large rooms, wood floors, and solid-core doors. These types of apartments can allow for some flexibility to accommodate a home office or reconfigure a smaller kitchen. This is something that can be hard to find in many new developments or refurbished buildings. Classic six apartments are mostly found on Manhattan’s Upper East and Upper West sides.

Don't be afraid of co-ops in NYC

"Co-ops are generally 10% less expensive than condos. Their rules are designed to protect the value of your apartment and ensure your neighbors are financially sound," says Matthew Steer of SteerKelly Team at Keller Williams. "As your broker, it's our job to make sure you qualify for the building you're interested in. We have a 99.9% success rate of getting buyers board-approved." Get in touch with us >>

In this Buy Curious column, Marcy Sigler, a broker at Compass, explains how this type of apartment has both benefits and drawbacks.

The question:

I’ve been looking at apartment listings, and I keep running into the phrase, “classic six” (and classic five, classic seven, and so on). What exactly does that mean, and why is it desirable? Will I pay more to live in one? Where are they located?

The reality:

“This term refers to a prewar apartment with six rooms, generally including the kitchen and bedrooms, and excluding the bathrooms, pantries, and entrance galleries,” Sigler says.

A classic six has a living room, a formal dining room with a window, a separate kitchen, two full bedrooms, and what was previously a live-in staff room—usually located off the kitchen with its own full bathroom or half-bath.

A classic six layout at 1212 Fifth Ave. in Carnegie Hill with an updated open living room and dining room is on the market for $4.65 million. 



A classic five lacks the staff room, while a classic seven has an extra bedroom, and the rare classic eight has an additional small room.

Pro Tip:

If you're not seeing enough apartments for sale in your price range or target neighborhood—and/or you'd like to avoid a bidding war—consider expanding your search to "off-market" listings. NYC real estate brokerage The Agency, a Brick Underground partner, uses technology to mine public records and identify owners who may be ready to sell, meaning you can meet and deal with owners before their homes hit the market.

What are classic sixes like?

These apartments are known for quintessential prewar features, such as oak floors, thick walls, solid-core doors, generous room proportions, a dining room, and the ultimate status symbol—a working wood-burning fireplace (though in updated iterations, the fireplace might be decorative).

Where can you find a classic six?

“You'll often find classic apartments in co-op buildings that date back to the 1920s through 1940, primarily on the Upper East Side and Upper West Side,” Sigler says. 

That said, developers of new construction are incorporating some of the classic six details into their current projects.

“In recent years, developers of condo buildings like 520 Park Ave. in Lenox Hill and 220 Central Park South in Midtown have co-opted the classic layout, combining those old-school embellishments with modern extras like garages, gyms, pools, and screening rooms,” Sigler says. 

The same can be said for developments in Brooklyn, notably Front & York in DUMBO and 11 Hoyt in Downtown Brooklyn. 

“So if you're enamored with the prewar style, you don’t have to confine your search to decades-old buildings—or pass a co-op board,” she says.

How many classic sixes are for sale at the moment?

Fewer than 45 apartments listed on StreetEasy are described as a classic six, primarily in Manhattan. Some have already been reconfigured from their original design or have been combined with neighboring units into much grander apartments. 

Prices for classic six apartments on the market range from $1.5 million (often for "as is" units)  to over $7 million. Most of the classic six prewars on the market currently fall in the mid-$3.5 million to $5 million range.

Why would someone want to buy a classic six?

The pros of purchasing a classic six include high ceilings of at least nine feet as well as prewar details like plaster moldings and cornices. 

Some people also like the fact that classic sixes have defined living areas. The apartment is typically divided into three zones—public (living room, dining room, library), private (bedrooms), and so-called staff quarters (including the kitchen). 

There are usually hallways separating these areas, which also help define the spaces

What are the disadvantages of buying a classic six?

A classic six can make you feel somewhat boxed in and many New Yorkers prefer open plans with fewer walls and living spaces that feel more expansive.

“The lack of an open layout could be a downside if you have small children that you want to keep an eye on,” Sigler says. However, renovated class six apartments often create a great room with a combined living and dining area. 

Finally, while a so-called staff room might have had a useful function when the apartment was built, these days it is likely marketed as a home office space or a bedroom.
