The New Museum, Manhattan's only institution dedicated exclusively to contemporary art, will open its ambitious 5,500-square-meter expansion on Saturday, March 21, 2026. The project was developed by OMA under the direction of Shohei Shigematsu and Rem Koolhaas, with Cooper Robertson as executive architect.

The design is a complementary addition to the original building designed by SANAA in 2007. It doubles the exhibition capacity and reorganizes the visitor flow.

The expansion integrates seamlessly with the original SANAA building on the Bowery, doubling the exhibition capacity and reorganizing the visitor flow. It introduces new vertical connections, intermediate spaces, and an entrance plaza that redefines the museum's relationship with the street, offering a more fluid and open experience for the public. 

The OMA expansion introduces new vertical connections, a central atrium visible from the street, and an entrance plaza that redefines the museum's relationship with the Bowery, offering a more open and dynamic experience for visitors. The faceted facade combines laminated glass with metal mesh, evoking the texture of the SANAA building while maintaining its own distinct identity. The main staircase, which traverses the atrium, functions as a "social condenser," connecting both buildings and organizing circulation.

The new building includes a Sky Room on the seventh floor with panoramic views of Manhattan, a 74-seat auditorium, an expanded lobby, a larger bookstore, and a restaurant designed with cork and polycarbonate, serving a menu by chef Julia Sherman and incorporating artist commissions and furniture by Minjae Kim. The upper levels house offices and artist incubation spaces, considered the "brain" of the building, along with a studio for resident artists and a permanent space for New Inc., the museum's art and technology incubator.

Among the permanent art installations are Tschabalala Self’s façade, a sculpture by Klára Hosnedlová for the atrium staircase, and an installation by Sarah Lucas in the plaza. The opening will coincide with the exhibition New Humans: Memories of the Future, which brings together works by more than 200 contemporary and 20th-century artists, exploring how technological and social advancements are redefining the idea of ​​humanity.

The building, named after the late curator and philanthropist Toby Devan Lewis, is unique in that it brings together two Pritzker Prize-winning architects who are still active. The opening will offer free admission during the inaugural weekend, with pay-what-you-wish hours on Thursdays and free entry for those under 18.

Since its founding in 1977 as a small office on Hudson Street, the New Museum has evolved into a global landmark, combining exhibitions, research, and programs supporting emerging artists in a space that continues to be a real-time incubator of ideas and art.

Project description by OMA

Our first cultural institution in New York is a new addition to the New Museum next door to its iconic SANAA-designed building at 235 Bowery. The New Museum has been growing in visitors, exhibitions, and activities. Its diverse engagements, including its expansive education programs, its cultural incubator NEW INC, and, of course, its globally recognized exhibition program have been transforming the institution into a cultural laboratory. We were asked to add a new building that provides much-needed space for its expanded activities and simultaneously reflects increasingly public ambitions—duplicating the program and square footage on a site immediately adjacent to the existing SANAA-designed building—part and counterpart, side-by-side.

This condition was entrenched in dichotomies. While dichotomies are inherent to museum expansions, they can suppress the full potential of the pair. We looked to less didactic, more unexpected, and maybe even romantically entangled relationships that could exist between two parts of a whole. Can one be highly infrastructural to give support and free agency to the other? Can it be two equal entities in complete harmony? Can the two be distinct and independent but reciprocal as a pair?

Our approach complements and respects the integrity of the adjoining SANAA building, while asserting its own distinct identity. The New Museum will be a synergistic pair working spatially and programmatically in tandem, offering a repertoire of spaces for the institution’s curatorial ambitions and diverse programs. We stacked the required programs exactly at the same level of the existing building—three floors of galleries, a permanent home for NEW INC, offices, and multifunctional education and event spaces—new and old conjoined. Ceiling heights of the newly connected galleries align on each floor, creating expanded space for exhibitions and horizontal flow between the buildings.

Galleries can be used singularly across the floorplate to host larger exhibitions or separately for diversity and curatorial freedom. Due to the horizontality of the site, the galleries in the new building increase in size on the upper levels while the galleries in the existing building decrease in size—the total area per connected floor remains balanced. A distinction between the two buildings is created by taking advantage of our site’s depth to insert an interstitial space, in between art and city, containing an Atrium Stair and dedicated gallery elevators for improved vertical circulation. This highly public face—starting from the exterior plaza and Atrium Stair to terraced multi-purpose rooms at the top—is a conduit of art and activities that provides an openness to engage the Bowery and the city.

The existing tower’s verticality treats the different programs within in the same expression. We wanted to create a healthy contrast by expanding the galleries horizontally and introducing two setbacks. An angled setback starting from the top of gallery stack to the street defines a new public plaza at the terminus of Prince Street that becomes a focal point and a buffer zone between existing and new. A second setback above the galleries makes the top of the building disappear, while opening up the upper-level terraces to the sky. Clad in laminated glass with a layer of metal mesh, the building appears monolithic during the day, establishing a unified exterior alongside the existing building’s metal mesh facade. In the evening, the transparency of the facade is enhanced as light permeates through its openings, exposing the museum’s anatomy.

The new, New Museum is a partnership of two different personalities with high compatibility—independent but in constant dialogue. The result is an expanded platform that provokes even more dynamic interactions between art, artists, and people, which are then exposed to communicate the museum’s civic ambitions to the city.

Office for Metropolitan Architecture (OMA) is an international practice operating within the traditional boundaries of architecture and urbanism. AMO, a research and design studio, applies architectural thinking to domains beyond. 

OMA is led by eight partners – Rem Koolhaas, Reinier de Graaf, Ellen van Loon, Shohei Shigematsu, Iyad Alsaka, Chris van Duijn, Jason Long, and Managing Partner-Architect David Gianotten – and maintains offices in Rotterdam, New York, Hong Kong, Doha, and Australia. OMA-designed buildings currently under construction are the renovation of Kaufhaus des Westens (KaDeWe) in Berlin, The Factory in Manchester, Hangzhou Prism, the CMG Times Center in Shenzhen and the Simone Veil Bridge in Bordeaux.

OMA’s completed projects include Simone Veil Bridge in Bordeaux (2024), LANTERN in Detroit (2024), Mangalem 21 in Tirana (2023), Aviva Studios – Factory International in Manchester (2023), Apollolaan 171 in Amsterdam (2023), Buffalo AKG Art Museum in Buffalo (2023), Toranomon Hills Station Tower in Tokyo (2023), Taipei Performing Arts Centre (2022), Audrey Irmas Pavilion in Los Angeles (2020), Norra Tornen in Stockholm (2020), Axel Springer Campus in Berlin (2020), MEETT Toulouse Exhibition and Convention Centre (2020), Galleria in Gwanggyo (2020), WA Museum Boola Bardip (2020), nhow RAI Hotel in Amsterdam (2020), a new building for Brighton College (2020), and Potato Head Studios in Bali (2020). Earlier buildings include Fondazione Prada in Milan (2018), Garage Museum of Contemporary Art in Moscow (2015), De Rotterdam (2013), CCTV Headquarters in Beijing (2012), Casa da Música in Porto (2005), and the Seattle Central Library (2004).

AMO often works in parallel with OMA's clients to fertilize architecture with intelligence from this array of disciplines. This is the case with Prada: AMO's research into identity, in-store technology, and new possibilities of content-production in fashion helped generate OMA's architectural designs for new Prada epicenter stores in New York and Los Angeles. In 2004, AMO was commissioned by the European Union to study its visual communication, and designed a colored "barcode" flag, combining the flags of all member states, which was used during the Austrian presidency of the EU. 

AMO has worked with Universal Studios, Amsterdam's Schiphol airport, Heineken, Ikea, Condé Nast, Harvard University and the Hermitage. It has produced Countryside: The Future, a research exhibited at Solomon R. Guggenheim Museum in New York; exhibitions at the Venice Architecture Biennale, including Public Works (2012), Cronocaos (2010), and The Gulf (2006); and for Fondazione Prada, including When Attitudes Become Form (2012) and Serial and Portable Classics (2015). AMO, with Harvard University, was responsible for the research and curation of the 14th Venice Architecture Biennale and its publication Elements. Other notable projects are Roadmap 2050, a plan for a Europe-wide renewable energy grid; Project Japan, a 720-page book on the Metabolism architecture movement (Taschen, 2010); and the educational program of Strelka Institute in Moscow.

Rem Koolhaas wwas born in Rotterdam on 17 November 1944. He began his career as a journalist working for the Haagse Post and also as a set designer in the Netherlands and Hollywood. He studied architecture at the Architectural Association School in London, and after winning the Harkness scholarship he moved to the USA. There he spent some time at the IAUS (Institute for Architecture and Urban Studies) in New York, a centre directed by Peter Eisenman. He later moved to Cornell University where he studied with Oswald Mathias Ungers.

In these early years of collaboration between Rem Koolhaas, Elia Zenghelis, Madelon Vriesendorp and Zoe Zenghelis, the name of the group while they were developing their first ideas and conceptual projects was more experimental: Office for Metropolitan Architecture – The Laboratory of Dr. Caligari. A time that served to consolidate initial ideas that would later lead to the formal founding of OMA in 1975 with his three colleagues.

In 1978 he wrote Delirious New York: A Retroactive Manifesto for Manhattan, which has become a classic of contemporary architectural theory.

The most important works by Koolhaas and OMA, from its foundation until the mid-1990s, include the Netherlands Dance Theatre at The Hague, the Nexus Housing at Fukuoka in Japan, the Kunsthal in Rotterdam, the Grand Palais of Euralille and Lille, the Villa dall’Ava, the Très Grande Bibliothèque, the Jussieu library in Paris, the ZKM in Karlsruhe and the Seattle Public Library.

Together with Koolhaas’s reflections on contemporary society, these buildings appear in his second book, S,M,L,XL (1995), a volume of 1376 pages written as though it were a “novel about architecture”. Published in collaboration with the Canadian graphic designer, Bruce Mau, the book contains essays, manifestos, cartoons and travel diaries.

In 2005, with Mark Wigley and Ole Bouman, he was the founder of the prestigious Volume magazine, the result of a collaboration with Archis (Amsterdam), AMO and C-lab (Columbia University NY).

His built work includes the Qatar National Library and the Qatar Foundation Headquarters (2018), Fondation Galeries Lafayette in Paris (2018), Fondazione Prada in Milan (2015/2018), Garage Museum of Contemporary Art in Moscow (2015), the headquarters for China Central Television (CCTV) in Beijing (2012), Casa da Musica in Porto (2005), Seattle Central Library (2004), and the Netherlands Embassy in Berlin (2003). Current projects include the Taipei Performing Arts Centre, a new building for Axel Springer in Berlin, and the Factory in Manchester.

Koolhaas directed the 2014 Venice Architecture Biennale and is a professor at Harvard University, where he directs The Project on the City, a research programme on changes in urban conditions around the world. This program has conducted research on the delta of the Pearl River in China (entitled Great Leap Forward) and on consumer society (The Harvard Design School Guide to Shopping). Taschen Verlag has published the results. Now is preparing a major exhibition for the Guggenheim Museum to open in 2019 entitled Countryside: Future of the World.

Among the awards he has won in recent years, we mention here the prestigious Pritzker Architecture Prize (2000), the Praemium Imperiale (2003), the Royal Gold Medal (2004) and the Mies Van Der Rohe Prize (2005). In 2008, Time mentioned him among the 100 most influential people on the planet.

Sho’s cultural buildings currently in progress include a museum expansion for the New Museum in New York City and a new arts centre with a theatre and concert hall for the University of Illinois at Chicago.

Expanding upon his built work for museums and cultural institutions, Sho engages the art world through various facets, from collaborations with artists such as Cai Guo-Qiang and Marina Abramović to structures and strategies integrating landscape and resiliency including an underwater art park and distinct structure for the ReefLine in Miami Beach and a mushroom pavilion in Mexico.

Sho’s works in the fashion industry span typologies and scales, from redefined retail spaces as mediums for branding to exploration of exhibitions and scenographies as narrative mediums. In Japan, Sho led the design and successful completion of the Coach flagship in Tokyo and is currently overseeing Harajuku Quest, a cultural and commercial platform connecting Omotesando and Harajuku. Sho has worked with fashion brands and houses, as well as museums, on major exhibition designs—Louis Vuitton Visionary Journeys in Bangkok; Dior retrospectives in Denver, Dallas, and Tokyo; Prada “Waist Down” in Tokyo, Seoul, New York, and Los Angeles; and Manus x Machina at the Met Costume Institute.

Sho has built several innovative workspaces and mixed-use buildings, including the China Central TelevisionHeadquarters in Beijing (2012), the Shenzhen Stock Exchange Headquarters (2013), Tenjin Business Center in Fukuoka, Japan (2021), and most recently, the Toranomon Hills Station Tower for Mori Building Co, Ltd. In Tokyo(2023). His innovation centre design for the Chicago Center for Education & Research for Discovery Partners Institute (DPI) and the University of Illinois System is currently underway.
