• Ludwig Mies van der Rohe (1886-1969) was a key figure in the International Style and designed the Seagram Building and the Farnsworth House
• Louis Kahn (1901-1974) known for his monumental, timeless designs, including the Salk Institute and the Yale University Art Gallery
• Eero Saarinen (1910-1961) designed the Gateway Arch in St. Louis and the TWA Flight Center at JFK Airport
• Philip Johnson (1906-2005) designed the Glass House and the AT&T Building (now Sony Tower), an early example of postmodern architecture
• Robert Venturi (1925-2018) and Denise Scott Brown (b. 1931) were influential postmodern theorists and designers, known for the Vanna Venturi House and the Seattle Art Museum
• Frank Gehry (b. 1929) is known for his sculptural, deconstructivist designs, such as the Guggenheim Museum Bilbao and the Walt Disney Concert Hall
• Jeanne Gang (b. 1964) is a leading figure in sustainable design, known for the Aqua Tower in Chicago and the Natural Resources Defense Council office in Santa Monica

Architectural Styles and Movements

• Modernism (1920s-1960s) emphasized simplicity, functionality, and the use of new materials and technologies
  • Subcategories of modernism include the International Style, Brutalism, and Minimalism
• Postmodernism (1960s-1990s) reacted against the austerity of modernism, incorporating historical references, ornamentation, and a more eclectic approach
  • Postmodern styles include Deconstructivism, which fragmented and distorted traditional architectural forms
• New Urbanism (1980s-present) promotes walkable, mixed-use communities that prioritize human-scaled design and traditional neighborhood structures
• Green Architecture (1990s-present) focuses on designing buildings that minimize environmental impact and maximize energy efficiency
  • Sustainable design strategies include passive solar design, green roofs, and the use of renewable materials
• Parametricism (2000s-present) uses computer algorithms to generate complex, organic forms based on a set of input parameters
• Critical Regionalism (1980s-present) seeks to balance universal modernist principles with local cultural, historical, and environmental contexts

Materials and Construction Techniques

• Steel and reinforced concrete enabled the construction of taller, more open buildings with larger spans and more glass
• Prefabrication and modular construction techniques allowed for faster, more efficient building processes
• Curtain wall systems, consisting of lightweight, non-load-bearing walls hung on a structural frame, became a hallmark of modernist architecture
• Sustainable materials, such as bamboo, cork, and recycled content, have gained popularity in contemporary design
  • Low-emitting materials and finishes improve indoor air quality and occupant health
• Green roofs and living walls integrate vegetation into building envelopes, providing insulation, stormwater management, and biodiversity
• High-performance glazing and insulation improve energy efficiency and occupant comfort
• Building Information Modeling (BIM) software enables more accurate, collaborative, and efficient design and construction processes
• 3D printing and robotic fabrication techniques allow for the creation of complex, customized building components

Urban Planning and Landscape Architecture

• Urban renewal projects of the 1950s and 1960s often involved the clearance of low-income neighborhoods and the construction of high-rise public housing
• Jane Jacobs' book "The Death and Life of Great American Cities" (1961) critiqued modernist planning principles and advocated for dense, mixed-use, pedestrian-friendly neighborhoods
• New Urbanism, exemplified by projects like Seaside, Florida, and Celebration, Florida, promotes walkable, human-scaled communities
• Landscape urbanism, which emerged in the 1990s, treats landscape as the primary organizing element of urban design, integrating ecology, infrastructure, and public space
• Green infrastructure, such as rain gardens, bioswales, and permeable pavements, helps manage stormwater and mitigate urban heat island effects
• Transit-oriented development (TOD) concentrates mixed-use, higher-density development around public transportation nodes to reduce car dependence and promote sustainable urban growth
• Adaptive reuse projects, such as the High Line in New York City and the BeltLine in Atlanta, transform obsolete infrastructure into public parks and catalysts for urban revitalization

Social and Cultural Impact

• Modernist architecture was often associated with progressive social and political ideals, such as egalitarianism and universality
• Postmodern architecture, in contrast, often celebrated pluralism, diversity, and individual expression
• The Civil Rights Movement and social unrest of the 1960s and 1970s led to a greater emphasis on community-oriented design and social responsibility in architecture
• Participatory design processes, which involve end-users and stakeholders in the planning and design of buildings and public spaces, have become more common
• Accessible design, guided by the Americans with Disabilities Act (ADA) of 1990, has made buildings and public spaces more inclusive for people with disabilities
• The rise of digital technology and social media has changed the way people experience and interact with the built environment, leading to new forms of public engagement and placemaking
• Architecture has played a role in shaping and reflecting cultural identities, from the regionalism of the Sea Ranch in California to the iconicity of the Sydney Opera House

Current Trends and Future Directions

• Sustainability and resilience have become central concerns in contemporary architecture, with a focus on reducing carbon emissions, conserving resources, and adapting to climate change
• Mass timber construction, using engineered wood products like cross-laminated timber (CLT), offers a more sustainable alternative to steel and concrete for mid-rise and high-rise buildings
• Modular and prefabricated construction techniques are becoming more sophisticated and widely adopted, improving efficiency and reducing waste
• The Internet of Things (IoT) and smart building technologies enable more responsive, adaptive, and personalized environments
• Biophilic design, which incorporates natural elements and patterns into the built environment, has gained popularity for its potential to improve occupant health and well-being
• 3D printing and robotic fabrication are opening up new possibilities for customization, complexity, and efficiency in construction
• Equity and social justice have become increasingly important considerations in architectural practice, with a growing emphasis on designing for underserved communities and addressing systemic inequalities
• The COVID-19 pandemic has accelerated trends towards remote work, flexible spaces, and touchless technologies, which may have lasting impacts on the design of offices, homes, and public spaces
