As much as sky-high office towers, like One World Trade and 10 Hudson Yards, represent NYC’s mighty commercial real estate market, they don’t paint the full picture. Adjust your eyes to street level, where activity is concentrating in tiny enclaves. Here, a look at three Manhattan “micro-nabes” that are heating up with smaller-scale, but significant, openings. FULTON STREET The city’s first iPic cinema — a plush, eight-screen, 500-seat space with reclining seats and quiet snacks — made a big splash when it opened at the South Street Seaport this month, marking the latest debut along Fulton Street’s white-hot commercial corridor. Indeed, from the World Trade Center to the East River, this Financial District strip is exploding with upscale options to keep pace with the neighborhood’s rapid rise.

This seven-building, 400,000-plus-square-foot development will include a 40,000-square-foot Jean-Georges Vongerichten food market, Milanese concept store 10 Corso Como and the new Pier 17 building, where Vongerichten and David Chang will open restaurants. “There’s more demand than supply right now, and you’re seeing the market respond,” St. Pierre adds. And it’s responding in a big way. Sure, construction is a great sign, but so are recent completions. A stone’s throw west, shopping-center operator Westfield Corporation made headlines in August when it opened its long-awaited 365,000-square-foot retail complex at the World Trade Center, which the Santiago Calatrava-designed Oculus partly houses. This striking edifice includes an Apple store, plus Cole Haan and Breitling shops. Of course, Westfield’s no stranger to the area. In 2014, the company and the MTA debuted the glassy $1.4 billion Fulton Center transit hub nearby, whose robust roster of shops includes a summer-opened Shake Shack. KENMARE STREET Sleepy Kenmare Street has awakened to a clutch of commercial development including Xi’an Famous Foods.Photo: http://www.xianfoods.com Midtown’s Restaurant Row could have a downtown competitor before long. Two blocks of Kenmare Street, a five-block-long thoroughfare that lies at the crossroads of Soho, the Lower East Side and Chinatown, have heated up this year with trendy culinary openings. Sources attribute the activity to the street’s prime location: It carries lots of hipsters from one nabe to the next, which proves great for business.

Fast forward to 2016, and Bread, the long-standing Italian joint at 20 Spring St., moved into a larger 85-seat space (with 40 seats for the seasonal sidewalk cafe) inside the chic 2011-opened Nolitan hotel at 40 Kenmare.

And in the subsequent months, they’ve benefited greatly from all the passersby. “The foot traffic there is crazy,” says Hardy. “It’s triple what we get outside Charlie Bird.” HUDSON SQUARE If you build it, they will come — and in a small pocket of Hudson Square, a new population of luxury condo residents has ushered in a wave of upscale restaurants. The stretch between Canal to Spring streets, and Greenwich to Varick streets, saw the rise of residential properties, like 255 Hudson St., 22 Renwick St. and 15 Renwick St., but not many places to grab a bite. Since 2015, a number of new spots have debuted, giving homeowners greater options close to home. “We identified Hudson Square as the very unusual Manhattan neighborhood that is underserved by restaurants,” says chef Ned Baldwin, and that’s why he opened the 60-seat Houseman at 508 Greenwich St. last summer.

Over at 234 Spring St., Thomas Carter and chef Ignacio Mattos debuted the 80-seat, Italian-centric Café Altro Paradiso in February. Industry experts agree the real formation of a neighborhood — like Hudson Square, a rezoned manufacturing district — follows a general formula. Sweat and muscles are the goal at The Dogpound gym in Hudson Square.Photo: Nigel Barker “You have the need for restaurants, which is slowly but surely getting there,” says Eastern Consolidated’s James Famularo, who’s repped a number of deals in this pocket, including that for Houseman and, down the block, 1,200-square-foot Sacco & Vanzetti (an eatery that opened last year). “The next phase is retail — and you’ll see them come in that order nine out of 10 times.” But locals can still burn off the calories close by. The Dogpound, a 3,800-square-foot gym that’s lured Adam Levine and Victoria’s Secret models, opened at 1 Renwick St. in April.
