Faces of Change

MICHAEL VAHRENWALD

A range of facade projects demonstrates an interest in material flows.

Local codes have improved the regulation of sustainability and energy efficiency in buildings but don’t yet fully address the sourcing of materials and their relative long-term energy costs. In this month’s Focus section, AN considers projects of various scales that rehabilitate damaged industrial sites, recycle construction materials, adaptively reuse existing structures, support landscape explorations, and design new possibilities for familiar elements.

Eight architects in London—Adam Khan Architects, Architecture 00, Mole Architects, SelgasCano, 6a, Barozzi Veiga, HNNA, and David Kohn Architects— have inserted a series of dynamic structures on the rehabilitated site of a former industrial natural gas plant. The stylized facades of Greenwich Design District create an engaging public space for offices, a food hall, and an experimental media center.

Testbeds is a project of New York–based firm New Affiliates with Sam Stewart-Halevy that repurposes mock-ups from construction sites to support community gardens. In Queens, they partnered with the Department of Parks and Recreation’s GreenThumb program to demonstrate how the mock-ups—normally thrown away after use in design and construction projects—can be recycled.

The architects hope Testbeds, currently on view at MoMA as part of its New York, New Publics exhibition, can be adopted by developers and expanded to serve other community gardens.

In Cambridge, Massachusetts, TenBerke’s adaptive reuse of the Lewis International Law Center at Harvard surgically rehabilitates Shepley, Bulfinch, and Abbott’s 1957 stone-clad concrete structure, adding square footage by expanding the top floor and reconfiguring the interior to accommodate more flexibility and social interaction.

The Four Rooftop Pavilion, by Los Angeles–based firms Found Projects and >Schneider Luescher, offers public programs within the recently completed Pingshan Children’s Park in fast-developing Shenzhen, China. The site preserves a landscape of banyan, eucalyptus, and lychee trees as a children’s play area to educate the next generation about the value of ecology and the natural environment.

Grand Mulberry, in New York’s Little Italy neighborhood, uses custom-designed red bricks manufactured by Glen-Gary to preserve neighborhood character and history. The 20-unit residential building, designed by Morris Adjmi Architects, houses the Italian American Museum on its ground floor and takes inspiration from the 19th-century Italianate style, inflected with Adjmi’s contemporary flair.

In small ways, each facade-forward project makes a difference in its context.

With buildings by Barozzi Veiga, 6a architects, and SelgasCano, among others, Greenwich Design District is an architectural playground.

TAR AN WILKHU

Architects: 6a architects, Adam Khan Architects, Architecture 00, Barozzi Veiga, David Kohn Architects, Mole Architects, SelgasCano Location: London Developer: Knight Dragon

“When David Kohn first told me he was designing some workspaces for North Greenwich which would have giant nude figurative statues by Damien Hirst on the facade I thought he was joking,” said Phineas Harper, chief executive of Open City, a British charitable organization dedicated to making architecture and neighborhoods more accessible and equitable.

Open City moved into the Greenwich Design District when it launched in 2021.

Back then some buildings in London’s first purpose-built creative quarter, realized on top of a former natural gas plant, were still

under construction, and they’ve steadily been opening since. A master plan from Allies and Morrison protects views of the adjacent Richard Rogers–designed O2 Arena, capping building heights at four stories. Studio HNNA laid out the circulation, creating a network of mini streets and squares with an array of plots to be filled on the condensed site.

The Design District in this sense is a big architectural experiment—and one that attracted big names. The developer, Knight Dragon, invited eight architects to design two buildings each, with the caveat that all offices work entirely independently. Adam Khan Architects,

Architecture 00, Mole Architects, SelgasCano, 6a, Barozzi Veiga, HNNA, and David Kohn Architects all stepped up, with the latter making good on its promise of nude figurines.

The latter’s two buildings, A4 and B4, are laced with playful references. Kohn used the glowing green of James Stirling’s Staatsgalerie for window framing and oversized brick pillars to support the base of A4, which is topped by a Hollywood-esque sign that reads DESIGN DISTRICT. Headless female nudes courtesy of Damien Hirst adorn A4’s corners. Six niches in B4 display works from local artists.

Less colorful, but still just as fun, Architecture 00’s C1 boasts a basketball court on its roof and a metal mesh net as the building’s envelope, allowing floor-to-ceiling sliding windows to fully open without the need for a balustrade. From above, the orange basketball court makes for a good photo, in contrast to the proudly gray building, while at ground level, the mesh provides porosity, allowing the building to be easily read. With its corner plot, the bright orange makes C1 a handy portal to the area. D1, by contrast, also by Architecture 00, is much more understated, eschewing any netting but retaining a set of expressive concrete decks.

Unlike any other firm, 6a architects opted for two almost identical buildings, both easily recognizable by their dramatic slanting roofs.

“If you do two buildings and one is better than the other, shouldn’t you just do the better one twice?” Tom Emerson, cofounder of 6a, related to AN in 2020. The two buildings, A2 and B2, are in part inspired by the late American artist Richard Artschwager, attempting, as Emerson remarked, to turn his “graphic, Pop Art expression into a sculptural form.” Architecturally, this manifests as a pair of buildings that celebrate the layers of construction, with a diagrid imprinted onto

the slanted roof. “It’s not an explicit reference but allowed us to enjoy working with these architectural products and layers which are ordinary in themselves but together can be interesting and playful,” added Emerson.

Mole Architects takes the opposite approach. “Mole’s two buildings [C2 and D2] are different from each other—one compact and angular, the other stacked like a ziggurat,” said director Meredith Bowles. “[They] play one against the other, the larger one heavy and solid, the smaller one with changing colors, like the flame of burning gas.” Internally, however, the two share the same sensibilities:

Made entirely from timber, they evoke the qualities of an old warehouse. C2 features stepped sides and diagonal Cor-ten cladding, while D2 serves up a shimmering facade—or more precisely, pyramidal profiled cladding with a two-tone color that changes with the direction of the light. Fins surrounding the windows in dichroic glass refract colored light over the facades. “The colors are inspired by a gas flame,” said Bowles, who added that the buildings are a nod to Victorian gas holders that originally occupied the site.

Along with its layout of the district, HNNA contributed two buildings: D3, which remains

Testbeds recycles mock-ups once treated as construction waste into investments in public space.

MICHAEL VAHRENWALD

Project leads: New Affiliates and Sam Stewart-Halevy Location: New York Structural engineering: Silman Engineering Contracting: Think Construction Mock-up storage: AM Glass Support: Cape Advisors, The Architectural League of New York, The Garden Conservancy, and NYC Department of Parks and Recreation’s GreenThumb program Architectural mock-ups are curious creatures. Peeking over construction fences, the isolated chunks of facade often appear like sculptures. However, unlike a Rachel Whiteread cast, once the assemblies have been tested for durability or visual cohesion they are typically thrown away rather than sold at the Gagosian. Designers of the project Testbeds— New Affiliates cofounders Jaffer Kolb and Ivi Diamantopoulou and architect and PhD candidate at Columbia GSAPP Sam Stewart-Halevy— were inspired to test alternative afterlives of the mock-ups through reuse instead of waste.

Testbeds proposes the reuse of architectural facade mock-ups from many of New York’s construction sites as support structures for community gardens. The city owns over 500 locations, which are run by volunteers.

Last year, the initiative, with support from the Department of Parks and Recreation’s GreenThumb program, completed its first pilot project in Rockaway, Queens.

The effort is also currently on view in the exhibition Architecture Now: New York, New Publics at the Museum of Modern Art as one of 12 projects that consider the city as a “fragile ecosystem in need of care.” In the exhibition, Testbeds exists as a built and speculative project through renderings, a board game, and a video of daily life at its first location.

Hyperrealistic renderings of different mockups propel viewers into the near future, with a white speckled panel tilted to form a quasi-Aframe, a greenhouse popping out of one of its openings. Another facade stays upright, forming a theater. Flipped horizontally in another, windows become skylights. The circular board game imagines the city as a “reconfigurable space instead of a space of consumption” where the players negotiate matching architectural prototypes with community gardens across the boroughs. Tiny 3D-printed mockups crisscross their way to new green homes.

In the video that flanks the corner, real volunteers work with the lush produce of harvest time while the first built Testbed, dubbed The Garden by the Bay, glints in the sun. StewartHalevy told AN that “the exhibition at MoMA seems to have captured the imagination of many different ‘publics’ in the city, and it has been wonderful to see the work of The Garden by the Bay gain visibility on this stage.”

I visited this garden on a misty spring weekday in Edgemere, a neighborhood on the Rockaway Peninsula in Queens. Jackie Rogers and Laquetta Little welcomed me to share their

experience directing the site. The Testbeds project couldn’t have come at a better time. The garden’s president and a longtime Edgemere homeowner, Rogers said the structure “helped people imagine the space” and what it could be. She recounted how, after a couple of years developing the garden near the northern end of the peninsula, watching the structure get built was a very exciting time, from seeing its foundations poured in late 2021 to witnessing its completion in late 2022. Its largest wall is faced in ridged high-performance–concrete panels originally used in a mock-up for a new condominium at 30 Warren Street in Manhattan.

The pieces enclose a massive gold-tinged aluminum window frame, with clear twin-wall polycarbonate sheets sliding within the frame that open for airflow and views. Each of the structure’s three rooms combines the programs of greenhouse, toolshed, and gathering space.

Aside from the salvaged materials, off-the-shelf materials like corrugated aluminum, raw lumber, and plywood compose the other facades, while CMU blocks and steel columns anchor the pavilion to its concrete floors and footings.

The garden’s organizers are already planning for expansions facilitated by their new Testbed venue. Rogers remarked that it’s “not about working harder [but] about working smarter,” as the garden has already doubled in size to around 15,000 square feet with the acquisition of a neighboring lot. The garden now has about 35 members who regularly volunteer. With its growth in membership and

the Testbeds addition came an increase in visitors, including NYC City Council Member Selvena N. Brooks-Powers, and Girl Scout troops. Rogers and Little are already imagining architectural expansions to accommodate a range of functions from garden support services to a community center. The current wish list includes wi-fi, electricity, PV panels, bug screens, and water access beyond a public hydrant to quench the thirst of vegetables, flowers, grapevines, and fruit trees. Across the street, there are many city-owned vacant lots now destined to become affordable homes under the Edgemere Community Land Trust, and perhaps, Rogers and Little pondered, even more public garden spaces.

Through the first Testbed installation and projections of many to come, Kolb, Diamantopoulou, and Stewart-Halevy imagine that mock-up reuse could become a systematic part of the construction process in New York. When asked about the project’s future, Stewart-Halevy said the team is “now in the process of forming a nonprofit, with the counsel of the Lawyers Alliance for New York, that will lay the legal and financial groundwork for Testbeds to continue.” He also shared that GreenThumb remains a partner in the project, and together they look forward to matching future homes for Testbeds elsewhere in the city.

The façade is the only part of the building that can be seen from the outside and has the function of communicating a message derived from its design. It therefore deserves special attention in every detail.

A façade that is well proportioned in terms of colors and materials, which facilitates the connection between the interior and the exterior, will generate an initial attraction for pedestrians, inviting them to enter.

This was the fifth time Kriskadecor clad the facade of the showroom during Milan Design Week. In this case, in addition to attracting the attention of both locals and visitors, the double-skin facade covered the imperfections of an old building.

Project Ecuador Pavilion Date 2015 Location Expo Milano, Italy Designer Zorrozua y Asociados

Kriskadecor's exterior cladding combines design and functionality. Thanks to the versatility and lightness of the aluminum links, large surfaces can be covered with infinite creative possibilities, providing color, texture and presence with a system that allows the reproduction of patterns, logos and even images thanks to in-house technology and a dynamic palette of RAL colors tested under solar exposure.

From the outside, its solid appearance provides privacy. From the inside, the transparency of the chain links allows full visibility.

Technical Features & Sustainability

In the case of Ecuador's pavilion during the 2015 Milan Expo, the folkloric motifs that made up the composition of the façade were a universal reflection of Ecuadorian culture and were inspired by the traditional textile craftsmanship of the Otavalo region.

The chain curtains offered the sensation of movement, simulating the flow of the fabrics themselves.

The system, designed and tested to guarantee a safe and durable structure, adapts to the shape of any building, is resistant, quick to install, easy to maintain and extremely light. The chains have been tested with wind gusts of 210 km/h.

In terms of sustainability, the open area of the chain links significantly helps to improve the thermal environment inside the building, reducing heat transfer from direct sunlight, thus allowing its ventilation. Furthermore, Both the chains and the profiles are aluminum, a sustainable and infinitely recyclable material.

A Surgical Intervention

TenBerke deftly blends new and old at Harvard’s Lewis International Law Center.

CHRIS COOPER

Architect and interior designer: TenBerke Location: Cambridge, Massachusetts Landscape architect: Michael Van Valkenburgh Associates Lighting designer: One Lux Structural engineer & envelope consultant: Simpson Gumpertz & Heger MEP/FP engineer: Altieri Sebor Wieber Sustainability consultant: Atelier Ten Civil engineer: Nitsch Engineering Geotechnical consultant: Haley & Aldrich IT, AV, and security consultant: Cerami Code consultant: R.W. Sullivan Signage designer: AFreeman

In spring 2022, Harvard University welcomed students into the newly renovated Lewis International Law Center, located on the northern stretches of the Cambridge campus, a stone’s throw from the Cambridge Common.

The 50,500-square-foot project was led by New York–based firm TenBerke (formerly Deborah Berke Partners), whose expertise in adaptive reuse has helped it transform the midcentury structure into a learning center that emphasizes social interchange, shared teaching, and flexible office spaces.

The original building dates from 1957 and was designed by Shepley, Bulfinch, and Abbott as an annex of the existing law library’s stacks, accompanied by a reading room and independent circulation desk. Its high-modernist design, executed with concrete, stone, and a curtain wall, ultimately proved outmoded for contemporary pedagogical demands. The renovation keeps the original library functions in place while adding an array of conference and meeting rooms, private offices, study carrels, reconfigurable classrooms, and client consultation rooms.

Any adaptive reuse project requires a near surgical methodology. TenBerke collaborated with structural engineer and envelope consultant Simpson Gumpertz & Heger to analyze the

existing structure and enclosure. “A deep investigation by structural and envelope specialists revealed opportunities but also limitations.

We realized we needed to be surgical with our interventions,” noted Ameet Hiremath, partner at TenBerke. “For example, we capitalized on the demolition of a mechanical penthouse to create a big opening to the top new floor and turned a blank facade into a transparent one that created a new front door and stitched pathways back into the campus precinct.”

Through subtraction and addition, the firm introduced new facade elements on the top-floor addition and at the entrance, using aluminum composite panels fabricated by Massachusetts-based Sunrise Erectors to secure the windows and provide shading. The replacement windows and the new high-performance glazing were treated with a pinstriped ceramic frit and placed over an insulated spandrel to optimize the window-to-wall ratio and mitigate solar heat gain and glare. The slenderness and depth of vertically oriented aluminum composite fins that shade the additions’ glazing also blend with the original structure’s tall stone piers. The result is not so much an addition as a melding of new and old.

Adaptive reuse is also an act of conservation that responds to present-day demands

for sustainability. The design team demolished just 20 percent of the existing building. TenBerke partnered with sustainability consultant Atelier Ten to develop a life-cycle assessment of the intervention to determine the project’s embodied carbon emissions and estimate total avoided emissions of the structure and enclosure.

“Overall, the adaptive reuse project saved about one million tons of embodied carbon emissions, which is equal to the annual energy emissions of 120,000 homes, according to the USEPA,” continued Hiremath. “The energy efficiency upgrades result in a 31 percent reduction in annual operational emissions, which is equal to 4.69 million kgCO2e cumulative emissions over the 60-year life cycle.”

With its refined and high-performance facade and newly public-oriented building program, the Lewis International Law Center will anchor this corner of Harvard University’s campus for years to come.

The city of Shenzhen straddles the border of Guangdong and Hong Kong and has undergone great change over the last half century.

The former fishing town, perched on the South China Sea, has grown from approximately 300,000 residents in 1980 to nearly 20 million today. Unsurprisingly, that growth has fueled a long-running construction boom that includes myriad civic institutions. One such project is the Four Roof Pavilion by Los Angeles– based firms Found Projects and >Schneider Luescher: Its airy design and public quarters act as a gateway for the recently completed Pingshan Children’s Park.

Pingshan Children’s Park, designed by WEi Studio, is located within a rolling landscape of Chinese banyan, eucalyptus, and lychee trees.

The pavilion’s design team drew on that bucolic setting, as well as taking inspiration from 11th-century Chinese landscape paintings, to develop the pavilion’s foliage-like color palette and open-air form.

The 13,000-square-foot project dates to 2020, during the height of the COVID-19

pandemic, when the design team was brought on to determine a program and design the castin-place concrete structural grid, a system that had already been approved by the local planning authorities. Due to travel restrictions, the design team was unable to visit the site during the design or construction phases and had to conduct all of its work from its home base in California and over Zoom. Those relatively hands-off circumstances called for the introduction of a straightforward building system.

Simplicity is the name of the game here: The rectilinear structural grid is topped by two steel roofs on the north and south facades, while the roof garden is supported by concrete. “During the design process, our thinking was to make the details and materials very simple, with nothing customized except for the centrally placed spiral stairwells,” noted Found Projects cofounder Ted Zhang. “We introduced a 13-foot-by-13-foot structural grid with three stories, and we developed several public-facing programs, such as a library, coffee shop, and roof garden.”

The north-facing canopy is, for the most part, topped with perforated metal panels, while the south one alternates between solid metal and translucent polycarbonate. In both cases, the materials are arranged in a diamond pattern that mirrors and obscures the cross-framing that supports the canopies from below. A hinge-like bracket embedded within the cast-in-place structural grid holds the canopies in place. The glazing comes in the form of a modular window wall facade system composed of two different sizes of glass.

“In general, we always were concerned because it is one big gesture of lifting the whole facade, and we wanted the building to be translucent, transparent, and light, and grappled with how to do that with a concrete-frame building,” said >Schneider Luescher cofounder Anton Schneider. “Obviously, there are very few materials that can do it as well as glazing, but acquiring high-performance glass would have blown up our budget. This was, in effect, a low-tech version of a high-tech building.”

I NNOVAT E YO UR V ISIO N and take your next project from render to reality The David Rubenstein Forum project at the University of Chicago utilized 60,000 square feet of custom Versa-Lok and custom fabricated wall panels that were manufactured by ATAS in 1.0 mm grey zinc. The panels were used as exterior wall cladding on this 166-foot-tall building consisting of 10 stories (a two-story base, and an eight-story tower).

Vertical zinc panels were chosen to express the idea of connectivity on the facade. Zinc was favored because it is a natural and durable material that is timeless and creates its own patina which protects the material for a long time. Zinc is very flexible, which worked well with this building’s geometry, and the way it reflects sunlight was appealing to the design team. The vertical panels also accentuate the height of the building.

The Grand Mulberry uses a custom-formed brick to animate a New York facade.

Architect: MA | Morris Adjmi Architects Location: New York Interior design: MA | Morris Adjmi Architects Museum architect: op.Architecture + Landscape Structural engineering: RCM Engineering Civil engineer: Sullivan Group Design MEP/FP: ABS Engineering Lighting: Delta Light Facade consultant: Buro Happold Engineering Masonry subcontractor: ARK Builders Brick manufacturer: Glen-Gery

In 1932, 98 percent of the heads of households in the area of New York City now variously known as Little Italy, Soho, or the Lower East Side were Italian emigrants, The New York Times reported.

This wave of immigrants, who largely arrived in the U.S. from the 1880s through the 1920s, were preceded by the Italianate, a mid-19th-century tripartite style of ornamentation and brickwork that changes as the building rises.

Almost a century later, the area’s demographics have changed. But for the facade of the Grand Mulberry, a seven-story, 20-unit building at 185 Grand Street completed last year at the corner of the area’s famed Mulberry Street, Morris Adjmi Architects (MA) looked back to the Italianate for its local resonance. “Emulating this tradition,” according to the office’s press materials, “the Grand Mulberry’s facade pattern consists of banding at the building’s base on floors one to two, pediment windows on floors three to five, and arched windows and a cornice on floor six.”

The zoning required the seventh floor to step back, an opportunity Adjmi seized to create an extensive terrace for the penthouse, then wrap the entire unit and bulkhead in gray metal panels. The metal intervention throws into relief the building’s main

feature: double-stacked running bonds of brick the color of old-fashioned red pavers.

Manufacturer Glen-Gery hand-molded each brick, creating distinctive half-spherical bulbs that bring to mind sheets of fresh ravioli.

The swells of the bricks create patterns of light and shade across the exterior, while their arrangements seem like echoes of historical tenement windows. (The actual windows are large tilt-and-turns with extruded aluminum surrounds.) The brickwork creates “a spectral reference to the heritage of the neighborhood,” the office stated, a connection made through both pattern and hue.

The project’s extensive use of mosaics also has a vaguely Italian, if not Italianate, quality. They spill out of the lobby to form a brass logo on the sidewalk. Another series serve as elegant black-and-white wayfinding in the lobby and public hallways. Stacked white tile patterns define the primary bathrooms in all 20 units, and a custom mosaic floor details the penthouse’s powder room.

In an unusual development agreement, the project replaced a row of not-very-Italianate townhouses that previously housed the Italian American Museum. The museum sold its three buildings in 2013 for $13 million, along with a

covenant to house its expanded ground-floor space in the new building, rent free, with a distinct Mulberry Street entrance.

Bricks are the key to the discreet insertion of a defining new building into an old neighborhood. “We worked closely with our masonry subcontractor, ARK Builders,” Morris Adjmi himself said in an interview provided to AN. “The unique masonry pattern—chosen for its ability to provide relief and add depth— could have presented a challenge during construction. But the level of detail put into the development of MA’s drawings and the quality of work provided by the subcontractor allowed for a smooth construction process.”

The finished result gains resonance through reference to the neighborhood’s poor, immigrant roots, while its pricing—ranging from second-floor one-bedrooms selling for $1.295 million to penthouse units marketed for $7.35 million—is altogether contemporary.

The Grand Mulberry’s exterior is “an example of how modern concepts can be applied to traditional methods and materials to develop unique and intricate facade designs,” Adjmi said.
