These were the most active NYC architects in 2024

These were the most active NYC architects in 2024
By Holden Walter-Warner, Research by Matthew Elo
It’s been a chaotic year for New York developers and landlords — and as a result, for the city’s architects — with the real estate landscape being altered by state and city legislation, the whims of
office tenants and actions by the Federal Reserve.
Nikolai Katz Architect emerged as the most active firm of the year, in terms of its number of initial permit applications for projects above a certain size. With 15 such applications, it was one of only
three architects to hit double digits.
Many of Nikolai Katz’s projects were on the medium or small end of that spectrum. Other firms, such as SLCE Architects and Gensler, tackled fewer but larger projects. SLCE, for instance,
surpassed 2 million square feet across seven sizable projects.
The year was full of challenges for the industry. The interest rate environment remained largely unforgiving, the state replaced the 421a multifamily tax break with 485x and changed the rules for
office conversions, while the city passed its most sweeping zoning overhaul since 1961.
Meanwhile, development sites in New York City became even harder to find.
“The scarcity of parcels for multifamily real estate development is increasingly difficult,” said Ariel Aufgang of Aufgang Architects.
But there’s hope on the horizon. Architects contact by The Real Deal noted the significance of the City of Yes legislation, which loosened zoning restrictions and increased the density allowed for
multifamily developments.
TRD’s most active architects ranking for 2024 is based on the number of initial permit applications filed for new buildings and renovations. It reflects the architects of record on permit applications filed through Dec. 3 for projects of 10,000 square feet or more.

AFFORDABLE HOUSING REQUIRES A NATIONAL COMMITMENT AND A CONVERGENCE OF URBAN PLANNING AND ENVIRONMENTAL RESILIENCY

Affordable Housing Requires a National Commitment and a Convergence of Urban Planning and Environmental Resiliency
A Federal Workforce Housing Czar is Crucial in Solving the Nation’s Housing Crisis
By Ariel Aufgang, AIA, Principal of Aufgang Architects
Despite universal recognition of an intractable national affordable housing crisis, not enough is being done to find and implement effective solutions.
According to JP Morgan Chase, “across the country, (housing) supply is scarce and prices continue to soar. Most people employed in full-time, minimum-wage jobs can’t afford to rent even a modest two-bedroom apartment—in any state in the country.”
The new administration in Washington, DC, has a historic opportunity to initiate effective new approaches to increase access to affordable housing. No specific policies have been revealed, but it is anticipated that the focus will be on the supply side. This is not surprising considering the real estate development background of the Chief Executive.
Solutions to this crisis require a multifaceted approach to overcome its deep-rooted causes. The new administration in Washington can get off the blocks quickly by making creation of workforce housing a national priority, with a determination comparable to landing Americans on the moon and bringing them safely home.
According to a recent analysis by the Center for American Progress, “Smart federal policy that addresses both housing and climate change is necessary to achieve a sustainable, healthy and inclusive economy that works for everyone… ”The appointment of a federal Workforce Housing Czar would be crucial in marshaling and focusing federal agency support and funding, coordinated with state and local initiatives. The Workforce Housing Czar would facilitate public-private partnerships comprised of private sector developers and financial institutions, nonprofits devoted to expanding affordable housing opportunities and government agencies at all levels. This must be done with the speed and scale required to achieve meaningful results.
It would ensure that the impact of existing programs is maximized by bringing together government, nonprofit and private-sector firms that are too often siloed. Chief among impediments to affordable housing development is NIMBYism, perpetuated by restrictive zoning regulations that limit multifamily density, and other provisions that inhibit development of affordable housing.
In New York State, while the Legislature has missed opportunities to address policy, programs and funding to significantly increase the supply of new and preserved income restricted housing, it did pass a State budget including the Governor’s ambitious plan to create half a million new housing units over five years.
In New York City the Mayor’s proposed “City of Yes” initiative would revise zoning codes to allow increased density and streamline the City’s slow and complex permitting processes that stall projects for years as their costs pile up. The New York City Council has come up with its own version of this proposed plan, which it may approve by the end of the year.
New York City rents have reached new historic highs in several boroughs. The gap continues to widen between housing costs and income. NYC households need at least $100,000 a year for food, housing and transportation. Families of four need fifty percent more. But the median income is $55,000.
To keep housing costs below the recommended 30% of income, the average New York City renter must earn about $134,000 per year. Yet about a third of New York renters spend more than half of their income on rent. This situation is unsustainable and jeopardizes the economic and social fabric of our communities.
Several states, counties and municipalities have begun using innovative approaches to encourage and incentivize affordable housing development and preservation. Many of these provisions call for financial consequences on jurisdictions and developers that refuse to comply, applying a carrot and stick approach.
In Florida, for example, new regulations aim at clearing away impediments to the creation of much needed workforce and affordable housing. New state laws there are specifically designed to ease density restrictions and overcome political resistance that sustain NIMBYism in counties and towns across the state, while at the same time providing financial incentives to encourage communities to allow the development of affordable housing.
Florida’s Live Local Act addresses the state’s entrenched affordable housing crisis. Enacted in July 2023, it facilitates denser housing development on cheaper land, chiefly by limiting the authority of local governments to block affordable housing with zoning and density regulations.
The Live Local Act permits construction of multifamily housing on any commercial parcel if enough of the units are dedicated to affordable or workforce housing. Developers in Florida are now able to use the maximum zoning allowed within a one-mile radius of the site, without having to contend with protracted and costly rezoning applications.
Such creative regulations expand income restricted housing supply by boosting funding for housing and rental programs, adding incentives for housing investment and encouraging mixed-use development in financially distressed commercial areas. Also, in this high-interest rate environment faster zoning and building permit approvals reduce interest costs, thus allowing the creation of more affordable units.
The Live Local Act requires that local governments in Florida must approve–without public hearings, a rezoning process, or land use change requirements–housing development on sites zoned commercial, industrial or mixed use, if at least 40 percent of the residential units are affordable for at least 30 years to households making a maximum of 120 percent of the area median income. It also reduces local authority to impose density and height limits. There are few other restrictions. The market rate units can be rental or condo, and they may be separated from affordable units.
This innovative approach by the state is encouraging counties and municipalities to also act on their own to revise zoning regulations in harmony with new statewide programs, amplifying the impact of income restricted housing development programs.
Florida is not alone in coming up with creative approaches to increase the supply of affordable and workforce housing. Successful programs are underway in California, in the Los Angeles and Bay areas, as a well as in Colorado and in towns in Westchester County, NY, and other states.
Harnessing America’s awesome collective talent and resources in finance, architecture and urban planning, commercial real estate development and public and social policy, requires clarity of vision and the political will on the part of our elected officials to quickly address our affordable housing crisis through new policies and programs.
Discussions of affordable housing development must also address the roles of urban planning and environmental sustainability which overlap to a meaningful degree.
According to archeologists, urban planning may date back to the Mesopotamian civilization. It is recognized that the ancient Egyptians utilized rudimentary urban planning techniques, and there is no question that the Romans took sophisticated approaches to urban planning. These include the utilization of wetlands to drain off tidal flooding from low lying cities, including Rome, and impressive infrastructure including the famous Roman aqueducts and laying out city streets to facilitate regular large deliveries of agricultural and other goods.
Cobblestone roads around the Imperial Roman Forum are rutted from the wheels of carts that delivered heavy loads of agricultural products brought to shops and markets in the city.
Today, modern environmental sustainability combined with urban planning can be seen in Edgemere Commons under construction in New York City. Developed on more than 9 acres in the Rockaway Peninsula in Queens, it is a 100% affordable planned community of 11 buildings with over 2,000 units in an area historically vulnerable to tidal flooding, especially when driven by hurricanes, which are occurring with greater frequency and intensity. My firm, Aufgang Architects, created an urban plan for Edgemere Commons, and designed individual buildings in that community. The features we specified to improve environmental resiliency ranged from raising mechanical systems above flood levels, directing storm water to run off into wetlands and incorporating green roofs to reduce heat island effects. Our urban planning for Edgemere Commons also includes features that improve the quality of life for its residents, such as inviting walkable paths with attractive trees and plantings and benches in central gathering places that increase outdoor social contact among residents.
Another impressive example that combines urban planning with robust environmental resiliency is Babcock Ranch near Ft. Myers, Florida, which suffered little damage when Hurricane Milton rushed ashore earlier this year. Babcock Ranch was designed to withstand increasingly fierce storms. (My firm was not involved in the design of Babcock Ranch.)
Babcock Ranch prioritizes sustainability and resiliency, featuring walkable villages that foster a strong sense of community.
All of the structures at Babcock Ranch are built to withstand 150 mph hurricane force winds. Its 150-megawatt solar farms and underground transmission system ensure the community rarely loses electricity. Nearly 90% of the site is preserved wetland that helps collect excess water.
The United States is the first and only country to land men on the moon and bring them back. That was over a half century ago and resulted from a national commitment. Today we face new challenges here at home. The same energy, focus and determined national commitment must be applied to expanding access to safe, comfortable and resilient housing for all Americans. We have the ingenuity, treasury and drive required to achieve this crucial goal.

NEW AFFORDABLE MULTIFAMILY MIXED-USE CONDO IN THE HEART TO HARLEM TO BRING HOME OWNERSHIP OPPORTUNITIES

New Affordable Multifamily Mixed-Use Condo in the Heart of Harlem to Bring Home Ownership Opportunities
A 73-unit affordable mixed-use condominium will be constructed at 132 East 125 Street at Lexington Avenue, bringing home ownership opportunities to the heart of Harlem.
Developed by Maddd Equities and designed by Aufgang Architects, the 13-story building will include 7,000 square feet of ground floor retail space and 45,000 square feet of medical offices on the second through fifth floors.
“We are pleased to enable affordable home ownership at one of the most vital intersections in Harlem,” said Ariel Aufgang, Principal of Aufgang Architects. “Homeownership strengthens the economic and social fabric of communities.”
“The new condo will feature larger apartments than usually found in new affordable residential construction in Manhattan, as well as an array of energy saving and environmentally sustainable features,” said Aufgang. “The new Harlem condo will provide residents with many appealing amenities.”
Of the 73 condo units, 31 will be 1-bedroom, 38 will be 2-bedroom and 4 3-bedroom units.
The development will meet HPD Homeownership Program guidelines for affordable condos, which calls for larger units than other programs. The units will be approximately 100 square feet larger than other HPD affordable programs.
Key features include:
- The building will be all electric, in compliance with Enterprise Green Communities criteria.
- Outdoor recreation space along with a fitness center and co-working space/lounge.
- Residents’ quiet enjoyment of their homes will be enhanced by the installation of window/wall noise attenuation materials and alternate means of ventilation.
“The anticipated approval of the City of Yes, providing measures to develop additional affordable housing throughout the City, underscores the importance of first in class affordable homeownership, such as this multifamily project in Harlem,” said Aufgang.
In the past 22 years Aufgang Architects has designed more than 14,000 units of affordable housing and 20 million square feet of built space.

CAN PEDESTRIANS AND BICYCLISTS SAFELY COEXIST WITH MOTOR VEHICLES ON COMPRESSED CITY STREETS?

Can pedestrians and bicyclists safely coexist with motor vehicles
on compressed city streets?
Pedestrians and cyclists are threatened by cars, buses and trucks in compressed traffic on city streets. How can urban planners solve this life and death problem? One answer may be found in Europe where the Netherlands has redesigned some city streets to provide a smoother and safer flow of people and motor vehicles. A traffic system, called “woonerf,” which means “shared space” in Dutch, blurs the barrier between street and sidewalk.
“Rather than one standard design, the system has many shared common elements,” says Vivien Ferrari, Senior Designer, Planning and Community Development at Aufgang. “Some have no curbs between areas for people and cars. Others may feature cobblestone or similar rougher road surface materials to encourage drivers to slow down and be more alert and cautious about pedestrians and cyclists.”
This system offers an array of potential benefits:
- Most importantly, slower, smoother traffic flow makes streets safer for close sharing among motor vehicles, pedestrians and cyclists.
- Retail stores may see an increase in business when it’s easier for shoppers to walk around a commercial area.
- More street space can be used to plant trees and other landscaping, beautifying urban areas.
- It can create public gathering spaces that enable social activities and cohesion and strengthen neighborhoods.
- Ideally, dedicated bike lanes lower individual use of cars and reduce traffic congestion.

Can such a pedestrian-centered infrastructure “work” in New York and other large American cities? Some steps can be taken to apply these principles, says Vivien Ferrari. “I would propose adding bike lanes to existing roads along with very clear signage. A series of barriers and distinct road and lane colors will also help to safely separate bike lanes from vehicular traffic. In areas with wide sidewalks, we would incorporate sitting areas and planters where space and property lines allowed.”
There are cultural, scale and infrastructural differences in the U.S. that may reduce the appropriateness and effectiveness of the Dutch system, starting with European drivers’ respect for the need to safely share streets with cyclists.
The COVID-19 pandemic brought a decrease in both vehicular traffic on New York City streets and reduced ridership on the subway and buses as many people worked remotely from home. This has turned around. Traffic is heavier and commuter ridership has substantially grown on public transportation, nearing pre-pandemic levels.
And there are many more pedestrians and cyclists on city streets which unfortunately has brought an expected increase in injuries and fatalities resulting from accidents with cars, trucks and buses. Adapting a European solution to New York and other American cities requires more than changing traffic flows on redesigned urban streetscapes, warns Aufgang’s Vivien Ferrari.
“It will also require a cultural shift based on educating drivers, pedestrians and cyclists,” she says.
Developers Want to Convert Unused Offices into Housing
Developers want to convert unused offices into housing— here’s what’s stopping them
By Lois Weiss
It’s a problem with an obvious solution. Since there are not enough cheap apartments at the same time many city offices remain empty, it would make sense to convert those fi distressed office towers into housing. But it’s not so simple.
Conversion projects are hugely complex, expensive, time-consuming and are stymied by bot city and state zoning and regulations. And without gobs of government assistance, the number don’t equate to cheap rentals.
Just look at Slate’s now underway conversion of the Hilton New York JFK Airport. Although the area was not conducive to pricey condos or market rents, thanks to a new program with financial and tax breaks, it will have 100% affordable housing with support services, said Ariel Aufgang, AIA, principal of Aufgang Architects, who designed the conversion. Without that government assistance, the Hilton would have sat empty.
At December’s announcement, Mayor Eric Adams said: “Advancing this plan to turn a vacant hotel into more than 300 new, affordable homes is a sign that we can think outside of the box and take advantage of the opportunities in front of us.”
But thinking is just not enough. Gov. Kathy Hochul has proposed both tax incentives and large buildings in some nabes. Similarly, Mayor Adams wants to allow offices built before 1990 convert and permit interspersed living and working. But Albany and City Council legislators must agree and have the changes blessed through the city’s Uniform Land Use Review Process (ULURP) that could take nearly a year.
The Real Estate Board of New York must also settle with unions on higher construction salaries.
“The city could change some requirements instantly, but they will say it will take six to nine months,” said Jay Neveloff, head of real estate at the law firm Kramer Levin.
Other issues include snaking water pipes and waste lines from those clustered at the core of office buildings. “If your building is wide open and empty, there is a clear path,” explain SIMS & ASSOCIATES, INC. Gerard Nocera of Revolution Real Estate. “But if you have tenants with long-term leases, to reworks your core with existing tenants is an impossibility.”
Lenders must also approve the change of use as it is contrary to mortgage documents.
For now, most conversions are expected to take place in slender and vacant old buildings and those with tenants just on the lower floors.
Those most well-suited are prewar, Class C proper8es, explained Woody Heller of Branton Realty, as they have narrow floors or bases with towers stacked like wedding cakes with smaller floors on top.
Meanwhile, full- and half-block buildings, even topped by a tower — such as 750 Third Ave. — become complex architectural puzzles. “We’re teed up to convert the building to residen8al but need tax support,” said owner SL Green’s Steve Durels. “We have to make structural changes and have a design in the can. It would add hundreds of apartments.”
The city’s most an8cipated conversion is of the famed Fla8ron Building at 175 Fifth. After its small, triangular floors failed to attract office tenants, it’s now slated for a luxury residential conversion led by Daniel Brodsky, Jeff Gural and the Sorgente Group.
The largest underway is by Gural’s company, GFP Real Estate, along with conversion powerhouse Nathan Berman’s MetroLoft Management, who, with architects CetraRuddy, are transforming the 1.1 million-square-foot 25 Water St. with new windows, ameni8es, atriums and glass floors on top.
GFP is also buying 222 Broadway for $150 million for yet another office-to-resi transforma8on while MetroLoft is planning a residen8al redo at Pfizer’s former headquarters at 219 E. 42nd St. at Second Avenue.
Downtown, architect Robert Fuller of Gensler, who worked on Vanbarton Group’s 180 and 160 Water St., said, “The biggest challenge was the deep floorplates.” At 160 Water, now known as Peal House, long-empty shajs were cut ver8cally through the building and five new floors were added on top.
Vanbarton bought that building in 2014 for $160 million — roughly $333 per foot — and could afford the costs while targe8ng just under market rate rents.
“We have a spectacular basis and have been able to do this conversion incredibly efficiently and therefore we are passing along the benefits to the consumers and the demand [for apartments] reflects that,” said Richard Coles of Vanbarton.
Not every developer is so lucky, as some office sellers want what converters say are “unrealis8c” prices.Other buildings expected to take the conversion plunge include 185 Varick St. and 95 Madison Ave.
At 250 Park Ave., on the market through Newmark, lease clauses allow tenants to be booted. Nevertheless, it may simply be torn down and redeveloped to match its neighboring and gigantic new JPMorgan Chase office building.
“It is clearly simpler and faster to rip down and build what you want,” Neveloff said.
Hotel vs. Office: Different Challenges in Commercial to Residential Conversions
Hotel vs. Office: Different Challenges in Commercial to Residential conversions
Two potential solutions to the housing shortage comes in converting underutilized spaces like hotels and office buildings. However, each conversio type faces unique challenges and should be tackled accordingly
BY ARIEL AUFGANG, AIA, PRINCIPAL, AUFGANG ARCHITECTS
There’s a national housing shortage, both market rate and affordable housing. At the same time there’s a large supply of empty office space and underutilized—and close hotels across the country. Owners and developers are increasingly examining the viability of commercial to residential conversions as a solution to both problems.
Hotels and office buildings present distinctly different factors to consider whe evaluating the feasibility of potential residential conversion opportunities.
Issues with Hotel-to-Residential Conversions
Hotels have a distinct floorplan compared to office buildings that makes hotel-tor residential conversion more practical and less costly. Systems such as water and wa lines are already in place and can usually be relatively simple to modify them in converting a hotel building to apartments units. As a result, a hotel conversion project can be completed faster and at a lower cost than converting an office building t residential.
Hotel conversions are not without challenges. “While some underutilized hotels are located in city centers, other potential conversion candidates are in less desirable locations next to airports or off major highways far from residential communities— factors that can suppress the value and appeal of residential conversions,” said Chris Walker, Planning and Community Development Project Manager, Aufgang Architects.
These issues can be of less concern in converting hotels to affordable or supportive housing rather than market rate.
Walker was on the Aufgang team that designed the residential conversion of the 36 year old former JFK Airport Hilton Hotel in Queens, the first hotel-to-residential conversion i NYC.
The shuttered 350-key hotel was converted to the new Baisley Pond Park Residences, a 100% affordable, 318-unit multifamily building offering supportive services to lowincome and formerly homeless families and individuals. The Baisley Pond Park Residences was developed by Slate Property Group and the nonprofit RiseBor Community Partnership.
Issues with Office-to-Residential Conversions
Office buildings are usually located in city centers where many people work, with clos access to public transportation, increasing their appeal as residential units, thus making them attractive to developers for conversion.
However, office-to-residential conversions often present design challenges that can b costly to address. Office buildings, despite large windows not commonly used i residential design, usually have deep footprints which deprive interior spaces of access to sunlight and outside air.
This can be overcome through innovative design, such as creating an open core or atrium through the height of the building. Also, elevators, stairways and systems such as water risers are usually centrally located in the cores of office buildings, requirin adding risers and lines to each new apartment unit, which increases conversion costs and lengthens construction time.
