Looking sharp, but will it fly with the neighbors? (Durst Fetner)

"My own feeling, and the feeling of board, is that we'd like this project to succeed," J.D. Nolan, chair of Community Board 4’s land-use committee, told The Observer. "The Dursts are great developers, and they have worked very well with us in the past. Nevertheless, this is a rezoning, and the public should benefit as well as the developer."

And so, the full board voted unanimously against Durst Fenter's new apartment building on the far West Side last night. One of the most dynamic designs of the decade, 625 West 57th Street calls for a swooping white pyramid that rises dramatically up from the Hudson like an origami dove taking flight. Designed by Danish wunderkinds Bjarke Ingels Group (aka BIG), the project has even decided to eschew LEED ratings in its quest for singularity.

Still, this was not enough to sway the board, which generally seems to like the design but still has too many issues with the details surrounding it to approve the project at its monthly meeting. The board's vote is merely provisional, though it will be given considerable consideration from officials down the line as they cast their vote for or against the project throughout the rest of the months-long public review process.

Last night, Helena Durst was in attendance to make her family's case, as she has for the past decade as the project has struggled from one plan to another—data center, car dealership, for-profit school, hotel. She looked appropriately pregnant for the occasion, which was held on the second floor of St. Luke's Roosevelt Hospital (the maternity ward is on the seventh) on the corner of 11th Avenue and 59th Street, two blocks from where Ms. Durst hopes the 740-unit apartment building might soon rise.

"This is an asset for the skyline," she said.

But not yet for the community, at least in its view. Their singular issue is affordable housing, of which there will be some 150 units. The sticking point is that those apartments will only be reserved for low-income tenants for 35 years. The board wants permanent affordability, instead. "As a community board, we are supposed to do the best we can to preserve and maintain our communities and keep them going," Mr. Nolan said. "As we see our neighborhood changing, we see so much luxury housing going up, and we feel that is not contributing to the preservation of our neighborhood."

The Dursts argue they cannot make the apartments permanently affordable because they do not own the site but have instead signed a 99-year land lease with a family that has owned the property for centuries. Now, there are some 150 different family members who have to be negotiated with, and any changes to the amount of affordable housing would require a renegotiation of the lease. Since the Dursts will not own the site in perpetuity, it is not clear the land's owners would agree to a permanent affordable housing provision.

Still, Councilwoman Gale Brewer has also expressed concern about the permanence of the affordable apartments, and since she has the final say on the project, it could continue to be a serious issue.

Other concerns included the appearance of the building along 58th Street. Currently, all the retail is along 57th Street, with entrances, loading docks and mechanical systems on the 58th Street frontage. The board hopes those spaces can be rejiggered, with shops, trees, anything really to make the streetscape, which is nearly a block long, more appealing to pedestrians.

Parking is an issue in two ways. One, board members argued there were too many spaces for a project in the middle of Manhattan. Two, there is an issue with the access to that parking, through a two-way driveway that cuts through the middle of the site and connects to the Helena, a rental building also owned by Durst Fetner on the southeast corner of 10th Avenue and 57th Street. The board wants that space cut down to one lane, with a public plaza created out of the excess space this would free up. "Curb-side drop-off?" Mr. Nolan said. "What is this, Dubai?"

A small community facility building drew concerns because the Dursts have yet to find a use for the building, after a failed bid to have the Manhattan Children's Museum move in. Now, they are looking at other childcare spaces, like day care or early education. Mr. Nolan thinks an art space could be good, too.

"This has always been a place for actors, artists, stagehands," he said. "They need housing they can afford, they need places they can perform. Without them, it's not the kind of New York I want to live in."

To try and counter the local opposition to the project, Durst Fetner made a full political push last night, bringing out speakers and testimonials from the Community Preservation Corporation and Citizens Housing, Settlement Housing Fund and Planning Commission (on affordable housing); New York Building Congress, Regional Plan Association and the Partnership for New York City (on design and construction jobs); members of 32BJ (on service and operations jobs); and the Audubon Society (on how normal buildings have troubling bird strikes and this one will not).

Still, this show of support failed to sway the board to vote for the project.

"We hear their concerns and we will continue to work with them on a solution," Jordan Barowitz, the Dursts' director of external affairs, said after the disapproval vote. "That being said, I think is a very compelling project for the community and the city. It provides desperately needed market-rate housing and 150 affordable units for decades. And it's an innovative and inspiring design. Great design makes for great places, which makes for a great community."

Update: The story has been modified to clarify that the full community board disapproved of Durst Fetner's building last night, not the land-use committee, though it also disapproved the plan at a meeting earlier in the summer. The story also misstated the location of the Helena. It is on the corner of 59th Street and 11th Avenue, not 10th Avenue. The Observer regrets the error.

5:45 The 116th annual REBNY banquet is just getting started at the New York Hilton. Chicago Title is having an invitation-only party on the building’s second floor.

5:46 As usual, the night’s official festivities begin with a cocktail party in the room adjacent to the Hilton’s main ballroom, where the dinner is held. Jason Muss, a principal at Muss Development, stands near the entrance to the room with Jared Kushner (owner of The Commercial Observer), Jared’s wife, Ivanka, and Fried Frank chief Jon Mechanic. “I love this party. It’s a great place to catch up with people,” Mr. Muss says.

5:50 The cocktail reception is quickly filling up. Simon Ziff, a principal at the financing company Ackman Ziff, stands near the open bar with his wife. “It’s overwhelming,” Mr. Ziff says. “Think of all the people here. A few seconds to say hi to each. That’s a lot of seconds.”

6:00  Hal Fetner, a developer who is building two prominent residential buildings with partner the Durst Organization, steps over to the bar. “The feeling in the room is always tied to the health of the market,” he says. So what’s the vibe? “Ask me later. It’s too early to tell. But I think things are good.”

6:01 John Santora, an executive at the real estate services firm who recently helped negotiate an agreement between landlords and the union that represents building employees, 32BJ, is chatting with C&W appraisal expert Brian Corcoran. “A lot of people worked on that deal,” Mr. Santora says of the negotiations. “I can’t take the credit for it.”

Steve Spinola, REBNY’s president, greets guests in the main room of the cocktail space. “We had to put a few tables upstairs,” Mr. Spinola says, indicating that attendance at the banquet has picked up from last year. “We got a lot of last-minute calls from people who wanted to come.”

6:17  Alan Weiner, the group head of Wells Fargo Multifamily Capital, one of the biggest lenders in the city, is chatting busily with Rob Speyer, one of the chief executives of the real estate firm Tishman Speyer.

Eric Deutsch, the former head of the Downtown Alliance who now is an executive at Montparnasse 56, a builder of observation decks, surveys the crowd. “My first job out of college in the early 1990s was with REBNY,” he says. “The market was terrible then and they barely had anyone at the banquet. They made me sit up front during the dinner to make it seem like people were here.”

6:30  Congresswoman Carolyn Maloney strides in. “I just secured us $300 million, a high-speed-rail grant to develop a line between Boston and New York. It’s very exciting,” she says, taking a crab leg. After she’s done with the morsel of meat, she holds the shell and looks for the waiter. “Where do I put this thing?”

6:32 The room’s cocktail banquet is about 75 percent full.

6:45 Robert Lapidus, an executive at the real estate investment company L&L Holding Company, becomes enraged when The Commercial Observer asks him if he is bidding on a leasehold interest in the Flatiron office building 114 Fifth Avenue, as is rumored. “We’re not here to talk about fucking business!” he yells, grabbing The CO’s notepad and tossing it.

Gary Green, head of the building services company Alliance, briskly and very politely retrieves the notebook while Mr. Lapidus hurls epithets at The CO. Acting like a true gentleman—and also looking the part in a finely cut tuxedo—Mr. Green apologizes for his friend. “You can’t do that! Knucklehead!” The CO overhears him say to Mr. Lapidus.

6:46  Kenneth Fisher, a partner at the real estate investment company Fisher Brothers, tells The CO that this is the first REBNY banquet he has been to in five years. “Every time this year, I’ve been playing golf in the desert [at the Bob Hope Classic].”7:00

Jeff Roseman, a retail leasing executive at Newmark Knight Frank, squeezes through the crowd. “It’s a great place to see old friends.” He greets Steve Green, the founder of the city’s biggest landlord, the REIT SL Green.

7:05 “This is my childhood,” Helena Durst, looking elegant in a flowing dress, says of the banquet. “Do you like Christmas? Do you like Sunday dinner? That’s what this is for me. I have so many memories of coming to this party.”

7:09 Deputy Mayor Robert Steel and Councilwoman Jessica Lapin walk through the room together, busy in conversation.

7:15 Guests are being pushed out of the cocktail reception into the main dining room. The dinner is about to begin.

7:16 “Do I like this party? It’s OK,” Kathryn Wylde, head of the Partnership for New York City, says. “I go to a lot of parties.”

7:25 The CO bumps into Woody Heller in the men’s room and mentions to him a rumor that Will Silverman, Mr. Heller’s colleague at Studley, doesn’t sit at a desk but stands. “It’s true,” Mr. Heller says. “He has a swivel desk that can be lifted and he stands at it rather than sits. He says it’s more comfortable.”

Does Mr. Heller do the same thing? “I pace,” Mr. Heller says.

7:40 The crowd, now dense, is heading into the main ballroom.

7:41 Bruce Mosler, a top leasing executive at Cushman & Wakefield, chats with friends outside the ballroom. “A lot of my good friends are in real estate, so this is a fun night for me, I get to see them all,” Mr. Mosler says.

7:42 Paul Pariser, a chief executive of the real estate investment company Taconic, stands nearby. Known as an avid skier, The CO asks him if he’s been to Colorado yet this season. “There’s no snow!” Mr. Pariser replies.

7:50 Howard Michaels, of the financing firm Carlton, is making his way into the ballroom. “If you’re in the real estate business and you’re not at this party, you have to have your head examined,” Mr. Michaels says. “Want to know something? I almost didn’t come. That was the pep talk I gave myself.”

8:00 Already murmurs are going around about where the after-parties are going to be. “I’m not going to an after-party,” says Bob Knakal, chairman of the brokerage firm Massey Knakal, which during the boom years threw epic REBNY parties. “I have dinner plans with my wife.”

8:05 Steve Berliner, an executive at the brokerage company Studley, flashes The CO a stack of his business cards, which he plans to hand out. “Tonight is the best recruiting night of the year,” he says. “I started getting recruited to Studley six years ago at this party.”

8:20 The CO tells Amira Yunis, a retail leasing executive at CBRE, that she looks stunning in her black dress. It’s true, the former model does. Asked what her plans for the year are, she jokingly grabs The CO by the shoulders and shakes, “Make millions and millions and millions of dollars!”

9:00 The ballroom is full. But few people are eating. In the center of the room, Mitch Arkin, an executive at C&W, is chatting. “I haven’t eaten yet,” Mr. Arkin says. “I’m not going to eat.” What is he using for fuel, a hungry CO asks. “Adrenaline.”

9:10 “After-party is at Nobu,” Matt Astrachan, an executive at Jones Lang LaSalle, tells his colleague Mitch Konsker and C&W retail executive Brad Mendelson. “JLL party at 10!” Mr. Mendelson booms.

9:15 Dessert is being served. Some kind of chocolate-coated-ball concoction. The CO is still looking for dinner, finds a steak and eats it. It’s not as rubbery as rumored, though it’s certainly overdone.

9:45  Steve Durels, SL Green leasing chief, and Paul Glickman, an agency leasing specialist at JLL, walk out chatting. The banquet is winding down.

10:00 Kent Swig, with a closely cropped beard and carrying a few extra pounds, makes his way out. “I’m having a beer,” he says.
