ABSTRACT:
Ho Chi Minh City, home to almost nine million inhabitants, is experiencing a growing occurrence of extreme weather conditions. Unfortunately, the current infrastructure to effectively combat flooding has failed to confront the challenges.
While authorities have taken measures to elevate the roads, an unintended consequence has emerged. Many people living in Saigon want their houses raised, and this convenient preventing flooding solution for homes on the main streets has affected the homes in the alley because of the big differents between ground to road level.
Sống với Lũ (Living with Flood) is a proposal using a metabolism approach with local materials and native building techniques to explore a new idea of a flexible system in alley houses that can resiliently withstand and evolve in the test of time and climate change.
MANIFESTO:
We are committed to creating sustainable and resilient communities through our Metabolist approach to architecture.
Our mission is to provide safe and secure living spaces for all, regardless of their social or economic background. By integrating a minimalist design philosophy, we prioritize flexibility and adaptability, allowing us to repurpose and adjust our designs to meet the distinct climatic and landscape conditions of regions like the urban slums in Ho Chi Minh City.
