Fantasizing about what’s behind the front doors of unique buildings and townhouses is a favorite New York pastime, and sometimes the reality is just as interesting as the fantasy. Here’s your chance to get a peek inside three incredibly unique properties currently on the market.

Where: 141 Clermont Avenue
Size: 2 bedrooms, 2 bathrooms
Asking: $875,000
Listed by: Win Brown and Doug Bowen
This rare detached house in Fort Greene, Brooklyn, dates back to the Civil War, which makes it ancient even for historic brownstone Brooklyn. What’s remarkable is that a lot of the character of this old home has survived — original entrance enframements and denticulated and bracketed cornices are in place, as well as the original wide-plank wood floors. Now the property ready for its next chapter, with expansion possibilities an alluring option in the house-crazy Brooklyn real estate market.
“Supersized” apartments are a hot sector of the market, The Real Deal magazine reports in its latest issue, as real estate developers look for ways to appeal to wealthy buyers. The list of new supersized buildings includes CORE’s upcoming Walker Tower development, but with the launch of sales at Walker Tower still a few weeks out, we thought we’d highlight three other supersized pads currently on the market.

Where: 213 West 23rd Street, Skyhouse
Size: 4 bedrooms, 4.5 bathrooms
Asking: $8,950,000

This Chelsea apartment isn’t called the “Skyhouse” for no reason. The mansion-in-the-sky, a triplex sitting atop a landmark building, has 5,000 square feet of indoor space along with an almost unheard of 6,000 square feet of private outdoor space. No neighbors, four exposures, and striking views of the Hudson River and Empire State Building — it’s a supersized home for a supersized lifestyle.

Looking for authenticity in a loft? Then we direct your attention to the live/work setup at 138 Mulberry Street in Little Italy, a blank slate of a space that has some of the coolest preserved details we’ve seen lately. The original brick archways immediately draw your attention, setting the massive 4,000-square-foot space apart from any other loft you’re likely to lay eyes on. As Little Italy gets absorbed by trendy neighborhoods like SoHo and the Lower East Side, it’s nice to see this reminder of Mulberry Street’s rich history.
