Léon Krier, the Luxembourg-born architect and urban theorist renowned for his critical stance against modernist planning and his influential role in the New Urbanism movement, passed away on June 17, 2025, at the age of 79. Known for his uncompromising critique of modernist planning and his vision for human-scaled, walkable communities, Krier leaves behind a substantial body of built work, theoretical writing, and educational influence.
Over a career spanning several decades, Krier advocated for a return to classical architecture and human-scaled urbanism, positioning himself as a leading critic of sprawling suburban development and high-rise modernism. His advocacy for walkable, mixed-use neighborhoods and his insistence on the cultural and social value of architecture challenged the prevailing norms of late 20th-century urban planning.
Urban structure as a set of organizational principles is largely independent of style. [But] Modernist architecture is generally so bad and arbitrary that it is almost totally inappropriate for most common uses and climates. - Léon Krier from The Future Of Cities: The Absurdity of Modernism

Spotlight: Léon KrierKrier's master plan for Poundbury, an urban extension to the historic market town of Dorchester in England, remains one of his most prominent legacies. Commissioned by the Duchy of Cornwall and developed under the patronage of Prince Charles, Poundbury exemplifies Krier's principles of traditional town planning, integrating residential, commercial, and civic spaces with an emphasis on walkability, local materials, and architectural forms inspired by vernacular traditions. His work and ideas have influenced generations of architects and planners around the world.
In addition to his design work, Krier was a prolific writer and lecturer. In his 2007 book Architecture: Choice or Fate, later revised and expanded in 2009 under the title The Architecture of Community, Léon Krier critiques the visual and spatial limitations of modernist planning. He frames urban environments as dialogues, arguing that neighborhoods should consist of varied textures, scales, and typologies, rather than follow rigid, functionally segregated structures such as those proposed by Le Corbusier. The book also explores strategies for scaling architecture to suit its context and examines placemaking techniques rooted in classical traditions. It is illustrated with analytical diagrams comparing the spatial logic of Modernist developments with that of traditional and New Urbanist cities.
He taught at several institutions, including the Architectural Association in London and Yale University, where he influenced generations of architects and urbanists. Krier was awarded the Driehaus Prize in architecture in 2003 and the Athena Medal from Congress for New Urbanism (CNU) in 2006. While best known for his urban master plans, Krier also completed a select number of architectural works. These include the temporary neoclassical façade for the 1980 Venice Architecture Biennale, the Krier House in Seaside, Florida, the Archaeological Museum in Sintra, Portugal, Windsor Village Hall in England, and the Jorge M. Pérez Architecture Center at the University of Miami.
Through his drawings, writings, plans, and teaching, he advocated for an urbanism rooted in continuity, locality, and human experience. His ideas remain embedded in ongoing debates around sustainability, tradition, and the shape of future cities, ensuring that his influence will continue to resonate with architects, planners, and thinkers for years to come.
