Sumet Jumsai is one of the most popular architects in Thailand. His complex and diverse building practice is paradigmatic of fourty years of architecture history in Bangkok and beyond. A number of his buildings are unfortunatley currently endangered. In the course of a research about South East Asian architecture, Sumet Jumsai became the focus of interest for a series of AG numbers. Two interviews with Jumsai ensued in 2013 and 2014 in Cambridge and Bangkok respectively, with the documentation of almost all his buildings in Bangkok. AG6 retraces moments of Sumet Jumsaiʼs biography while concentrating on the documentation of the last days of his penthouse on top of the condominium complex he built in 1973 on the Chalermnit Court near Sukhumvit road.
