We’re pleased to share that Christian J. Lange and Mono Tung’s collaborative MArch research studio, conducted in Fall 2023 within the Faculty of Architecture at the University of Hong Kong, has been featured in the latest issue of the HKIA Journal. The studio focused on AI-driven design strategies for the renewal of aging public housing estates in Hong Kong.

Their article, “Reimagining Choi Hung Estate: AI’s Role in Future Public Housing Design,” highlights innovative design methodologies that leverage artificial intelligence to reimagine one of the city’s most iconic housing developments. The piece explores how tools such as Midjourney and Stable Diffusion were integrated into the architectural design process, enabling students to generate speculative yet contextually grounded proposals.

Addressing key issues of urban renewal, housing density, and community identity, the studio demonstrates how computational design—when paired with cultural sensitivity—can offer a forward-thinking model for the future of public housing in Hong Kong and beyond.

I am very happy to be part of the upcoming 1-Day symposium on AI in Sharjah, UAE. The Interrogating Intelligence in Artificial Architecture symposium will be hosted by AUS’s Department of Architecture on Sunday, March 9th.

Interrogating Intelligence in Artificial Architecture

Date: Sunday, March 9
Time: 1-4 p.m.
Venue: AUS Main Building, Lecture Hall B

As the efficacy of artificial intelligence develops and its use and application becomes more widespread, academia and industry are bracing for significant change. AI is not going away and it will get smarter. The question design educators are facing is not “if” but “how” to incorporate artificial intelligence into the classroom. CAAD is committed to lead the discussion on developing an ethical, generative pedagogy that propels our students toward cutting-edge design technologies and careers. This symposium intends to probe the limits and infinitude of machine learning’s impact on the built environment. The panel comprises leading researchers, educators, practitioners and industry leaders who have been using AI to rethink architectural design and production in various ways. The event will feature five presentations on the use of AI with regard to architectural design and education followed by a moderated discussion.

Presenters / Panelists:
Omran Alowais, Founder ARDH
George Guida, Architag / Harvard GSD
Anna Wanyu He, CEO of xKool / Lookx

I am thrilled to share the upcoming book launch at HKU of “Cities of Repetition,” co-authored by Christian J. Lange. The book launch is part of HKU’s discussion series and will be held on 23 October, 2024.

Abstract:
Housing is one of the most fundamental elements of urban growth, and Hong Kong has for decades hosted some of the most intense built environments on the planet. The city’s urbanization has produced unparalleled living conditions in terms of building scale and density. Due to lack of space, topographical constraints, political conditions, and extremely high population density, Hong Kong became an incubator for the development of housing models and tower typologies for high-density living.

“Cities of Repetition provides a comprehensive graphic documentation and analysis of the largest Hong Kong housing estates built by private developers from the late 1960’s through the early 2000’s. The original drawings and diagrams illustrate and compare the ultra-dense, mass-produced, highly repetitive built environments in which hundreds of thousands of Hong Kong residents live. Drawings, diagrams and photographs not only display the immense scale of the housing estates within the city, but also present the hundreds of similarly planned housing units and their subtle differences. Detailed diagrams compare statistical information to show how the planning of these massive estates has evolved over the past decades to efficiently conform to building regulations. The publication and larger research project present a comprehensive analysis of the architectural and spatial realities of some of the most densely populated, urban environments ever built. Overall, the project presents an investigation and analysis of how hundreds of residential towers in Hong Kong, built in the final decades of the twentieth century, were shaped by regulatory and economic forces that radically standardized the city and limited architectural specificity in relation to context.

We’re pleased to share Christian J. Lange’s recent participation, alongside co-author Jason Carlow, in an international webinar exploring urban density and repetition in architecture, featuring a cross-cultural dialogue between New York and Hong Kong.

New York and Hong Kong are dense, intense vertical cities. In this truly international webinar, architects and educators Jason Carlow, a professor of Architecture at the American University of Sharjah, UAE and Christian Lange, a professor at the University of Hong Kong, described their joint study Cities of Repetition. Their book provides a powerful, comprehensive, graphic documentation and analysis of the largest Hong Kong housing estates built by private developers from the late 1960’s through the early 2000’s. Their images both illustrate the ultra-dense, mass-produced, highly-repetitive built environments in which hundreds of thousands of Hong Kong residents live but also capture the subtle differences in the variations of repetition.

After their presentation, the speakers were joined in dialogue with NYC housing scholar Nicholas Dagen Bloom, Professor of Urban Policy and Planning at Hunter College, and Museum director Carol Willis for a discussion of the comparative housing models of New York, Hong Kong, and other cities where repetition is both a development and a housing strategy.

We are happy to share that Cities of Repetition: Hong Kong’s Private Housing Estates, co-authored by Christian J. Lange and Jason Carlow and designed by Kay Bachmann is printed and up for sale!

Cities of Repetition provides a comprehensive graphic documentation and analysis of the largest Hong Kong housing estates built by private developers from the late 1960’s through the early 2000’s. The original drawings and diagrams illustrate and compare the ultra-dense, mass-produced, highly repetitive built environments in which hundreds of thousands of Hong Kong residents live.

Detailed diagrams compare statistical information to show how the planning of these massive estates has evolved over the past decades to efficiently conform to building regulations. The publication and larger research project present a comprehensive analysis of the architectural and spatial realities of some of the most densely populated, urban environments ever built.

While there are many positive aspects of Hong Kong’s housing estates, including remarkable urban density and economic viability, new building codes that allow for and encourage variation and heterogeneity for mass housing developments, must be developed and implemented if cities of the future are to provide humane and diverse modes of housing to sustain socially viable, heterogeneous communities.
