Senp Kay:

GreenSpace Collaborative in partnership with Builders Without Borders’ Haiti team completed its second alternative structure in Port-au-Prince in February 2012.

The Senp Kay (Simple House) utilizes prefabricated, tilt-up, plastic bottle panels and light straw-clay walls. This modular wall design incorporates the structural integrity and efficiency of the tilt-up panel, the creative repurposing of plastic bottles, and the simplicity of light straw-clay infill.
