Overview

Harvard GSD’s Department of Architecture presents a public lecture by Chatpong Chuenrudeemol, founder of Bangkok-based CHAT Architects, titled “Bangkok Bastards.” The lecture takes place in Piper Auditorium, Gund Hall, on March 31, 2026, and is free and open to the public, with a live stream available on the GSD event page. It is hosted by GSD faculty member Grace La.

The lecture draws on Chuenrudeemol’s decade-long research into informal, vernacular, and unsanctioned construction in Bangkok: structures built by everyday people from locally sourced and scavenged materials to solve immediate urban problems. This body of work forms the intellectual foundation of CHAT Architects’ design methodology and has expanded in recent years into rural Thailand under the name “Rural Crossbreeds.”

Focus

“Bangkok Bastards” are Chuenrudeemol’s term for a category of vernacular urban buildings that fall outside official architectural discourse: temporary construction worker shelters, informal settlements, underground sex-motels, and other improvised spatial solutions scattered throughout Bangkok. Built cheaply, often illegally, and without professional architects, they are typically dismissed as urban blight.

Chuenrudeemol’s argument is that these structures represent some of the most honest and resourceful examples of built problem-solving in Thailand’s urban landscape. Far from being failures of design, they are sophisticated responses to conditions that formal architecture rarely addresses: extreme cost constraints, legal ambiguity, rapid change, and direct user agency.

The practice methodology Chuenrudeemol calls “Bastardizing the Bastard” involves taking existing vernacular types and crossbreeding them with new programs, urban conditions, or ecological concerns to generate hybrid architectural projects that remain rooted in local material and social logic rather than imported formal language.

Bastards are honest, clever, and improvisational responses to the city’s challenges, and perhaps the most authentic and relevant examples of vernacular architecture in Thailand’s urban landscape.

Program

Lecture

Chuenrudeemol will present the development of the Bangkok Bastards research and its application to CHAT Architects’ built work, tracing the move from documentation of informal typologies to design practice. The lecture will also address the firm’s expansion into rural Thailand through the Rural Crossbreeds initiative, which focuses on preserving indigenous cultural knowledge and generating new economic models for rural communities through design research.

Related Studio

The lecture connects to an active GSD Option Studio (STU-1315, Spring 2026, 8 units) in the Department of Architecture, suggesting the Bastards research is being engaged at a pedagogical level, not only as a public lecture topic.

Speaker

Chatpong (Chat) Chuenrudeemol is the founder of CHAT Architects, a Bangkok-based practice engaged in multi-scalar projects derived from the Bangkok Bastards research. His work has received the Silpathorn Award, Thailand’s highest national recognition for contemporary artists, presented by the Ministry of Culture. CHAT’s work has also won multiple international awards. Chuenrudeemol’s practice spans design research, built projects, and community-based initiatives in both urban and rural contexts across Thailand.

Audience

The lecture is open to the public and will be live streamed, making it accessible beyond the GSD campus. Its primary audience is architecture students, researchers, and practitioners interested in vernacular urbanism, informal settlements, and non-Western design methodologies. A broader audience engaged with urban informality and Southeast Asian urbanism will also find the lecture directly relevant.
