A few years before this limestone duplex was built, Prospect Heights was enjoying the success of one of its very own, the original “it” girl, famed silent film actress Clara Bow. And just as Clara became synonymous with the “Roaring Twenties”, the residence at 645 Carlton Avenue is typical of the classic row houses one finds throughout the tree-lined streets of its Brooklyn environs.

From the moment you first enter through the gorgeous Palladian arch, there is no mistaking the timeless details that make this carefully restored 2BR/2BA parlor/garden apartment something truly special.

Whoever coined the term “the lap of luxury” was clearly thinking of The Mayfair’s apartment #2BC at 610 Park Avenue. This opulent residence, with a $20 million price tag, is so lavish you feel elegant just looking at it. The gorgeous marble entrance gallery is a perfect first impression, setting the tone for the rest of the apartment.

The Mayfair was originally the Mayfair Regent Hotel, built back in 1925 by Rosario Candela’s famous partner J.E.R. Carpenter. The building was converted to 15 floors of beautiful condos in 1997.

Greene Street in SoHo is the kind of block you walk down and can’t help but marvel at its rich collection of cast-iron architecture — arguably part of the most extensive of its type in the world. Close your eyes and you can almost (okay, maybe at 3AM, but work with me here) hear the clip-clop of the horse drawn buggies reminiscent of the year 1880, when this undeniable gem was built.

Fortunately, although modern in its amenities (it was converted to loft condos in 2000), 20 Greene Street and the apartments within retain much of their 19^th century charm, from the building’s classic facade to unit 2B’s high ceilings with exposed piping and cast iron Corinthian columns.

Maybe money can’t buy you love but it can buy you this beautifully renovated and carefully restored apartment at 1 West 72^nd Street in the legendary Dakota listed at $14.5 million.

Designed by Henry J. Hardenbergh and completed in 1884, the Dakota is one of the world’s most renowned residential buildings. Designated as both a New York City Landmark and a National Historic Landmark, its residences boast many of the building’s original 19th-century details including 13-foot ceilings, soaring doorways, plaster moldings, exquisite hand-carved woodwork, hardwood flooring, pocket doors, shutters framing the windows, and wood-burning fireplaces – and at least one interesting 21^st century detail: Yoko Ono calls it home.

Imagine what it would be like to live here

High above the East River, atop the Hospital for Special Surgery, sits this elegantly renovated 3-bedroom, 4-bath Lenox Hill residence in the The Belaire. Designed by Frank William and Partners, and completed in 1988, The Belaire is true to its name, offering sweeping “airy” views of the river below, the bridges that span it, and the skyline of the city it calls home.

Life in Soho should be a perfect blend of comfortable living and lively entertainment. Well, this beautiful 3,167 square foot loft at 104 Wooster Street understands that perfectly. That’s why it’s fully equipped with a spacious great room, currently sectioned off into smaller seating areas. Now, you can have a conversation with a few friends while the kids play safely in another corner of the room. Or maybe you prefer to float freely through a sea of guests at the awesome parties you’ll throw. Either way, apartment #2S is ready to accommodate you.

The phrase “stunning views of Central Park” could have been first uttered for this elegant and meticulously gut-renovated Century Condominium apartment. From nearly every vantage point you feel like you’re walking on the treetops of New York City’s renowned oasis of green – a view that has been enjoyed by the inhabitants of #14J since the Century opened in 1932 on the former site of the historic Century Theater.

Sharing an Art Deco motif with its sister building The Majestic (on 72nd across from the Dakota), the 32-story Century stands out among its predominantly Beaux-Arts neighbors and became part of the Central Park West historic district in 1985.

See what it feels like to tiptoe through the treetops

The Hudson River may flow in two directions (yup, north and south, look it up!), but the lucky owners who combine the two full floor contemporary lofts (#5 and #6 ) at 471 Washington Street will be too busy to notice while taking in the stunning protected views of this majestic waterway.

A large part of the appeal of New York City is the historical nature of the buildings. However, how many buildings can boast that they were once own by not one, but two mayors? Well, the 4-story townhome at 405 Clinton Avenue has those bragging rights, and it’s on the market for a new owner.

The townhouse was initially designed in 1889 by William Bunker Tubby, the architect responsible for Pratt Institute’s library. He designed it for Charles A. Schieren, one of Brooklyn’s last mayors. It’s rumored that the home was also the residence of Brooklyn’s jazz-Age mayor Jimmy Walker, many decades before its current owners purchased it in 2009. After paying $1.75 million for the landmarked building, owner Sean Wilsey and his wife Daphne Beal gutted the entire place, adding roughly 100 new windows and a patio among other things.

Demi Moore made news this week when word got out that she would be putting her San Remo triplex up for sale for a whopping $75 million. While no listing or photos of the 7,000-square-foot 145 Central Park West space have surfaced (apparently Moore is quietly showing it), one of 6sqft’s reporters did some sleuthing and found these old black and whites from the Museum of the City of New York which pretty much meet the specs: of the two triplexes in San Remo today, one was made combining the only two-story unit in the building and the mechanical space above it. Moore and then hubby Bruce combined a two-story unit with the space above it…

Though we’re sure the decor has changed since the Spring of 1937 when it was occupied by Theodore C. Wiehe, with a little bit of imagination we bet you can fill in the gaps. So sit back, relax, and enjoy this blast from the past. And if you’ve got some money to spend, make Ms. Moore an offer. You’ll also be granted the record of “the person to have spent the most money on a co-op ever“. A win?
