This July marks 15 years of 2001 , a practice dedicated to producing architecture and far beyond. Since its founding, 2001 has engaged with territories, buildings, spaces, and ideas, navigating the complex environments shaped by society. Founded in 2010 by Philippe Nathan, and led since 2014 in partnership with Sergio Carvalho, the studio’s name 2001 symbolizes a discreet yet strategic approach to architectural and spatial intervention. Over the past decade and a half, the practice has continuously contributed to broader cultural and urban debates. Among its milestones are two contributions to the Venice Architecture Biennale (2012 & 2018), where the office provocatively explored possible futures for spatial and architectural planning in the region. This line of critical engagement led to the office’s selection for the "Luxembourg in Transition " process (2020–2022), where it collaborated with researchers to develop a vision for a decarbonized, food-autonomous, and climate-resilient bio-region. This methodology later informed the development of a GREENBELT around Luxembourg’s central agglomeration, an effort toward defining a "Luxembourg Metropolis" marked by ecosystemic calm, coolness, food resilience, and urban joys. Complementary to this, a conceptual study on the Interurban Green Zone emphasised the ecological, agricultural, and climate-mitigating importance of the landscape between Luxembourg’s centre and south, highlighting its potential not just for biodiversity but as vital infrastructure for food production and water management. These themes also shaped one of the office’s major ongoing projects: the redevelopment of the former Josy Barthel national stadium into a new residential neighborhood. The STADePARK masterplan, now finalised, is gradually transforming the site into a long-term, forward-looking urban quarter. While 2001 is fundamentally an architecture studio, its work consistently expands the scope of what architecture can mean. From emblematic single-family homes like HERCULE (Mondorf-les-Bains, 2016—shown at the 2022 Venice Biennale) and FANY (Dudelange, 2018), to rethinking how domestic spaces engage with landscape, economy, and contemporary living models. These ideas extend into the studio’s public commissions; like the MAISON (jeune) PEUPLE in Differdange, a youth centre that applied industrial construction techniques to deliver triple spatial volume on a modest budget, serving both youth and the broader community. Similarly, SPEKTRUM —the transformation and extension of artist Albert Hames’ estate in Rumelange— embraced the patina and character of the site, reactivating it as a centre for immersive art, tourism, and community engagement. These lessons continue to inform the practice’s current work, including the PETERBOS Sports and Community Centre in Brussels, in collaboration with FELT (Ghent), and especially s^^^h ; a major project with Civic (Amsterdam) to transform the former slaughterhouse in Luxembourg City into a vibrant civic centre, with the potential to become a cultural and social anchor for the emerging metropolis. As 2001 looks ahead to the next 15 years, it remains committed to engaging deeply with the challenges of our time, working with architecture as a tool to foster a progressive sense of place, belonging, and community.
