By creating units of living spaces that attach to a singular unifying element of structure, the design creates an anchor from which each programmatic element is attached while simultaneously serving as the principal sustainable feature. This is broken down to create independent modules consisting of passive ventilation, circulation, living space and outdoor space. The modules combine together to create a dwelling that grows with the family and can be adapted to their needs. The main material that used throughout the structure is bamboo. Bamboo is renewable, fast growing and available locally in abundance. It can be reclaimed and used in flooring, furniture, chipped to make insulation or for other agricultural uses, to name a few. All corrugated metal can be recycled and reused.
The climatic conditions of the region are a natural resource that we sought to harness in our design. The goal is to minimize solar gain and capture as much air current as possible. Our design hinges around stack ventilation. The stacks draw hot air up and out, passively cooling the home. Additionally, the rainy seasons were considered. The home was elevated above a potential flood line and cisterns were designed to capture as much rain as possible for use in a dual plumbing system that would serve to supplement their water supply for non-potable uses, particularly during the dry seasons.
