Generative tools are used to generate rapid products and they support mass customization. These properties are mostly needed in the case of an emergency when rapidity in design and application means much more than anything else. Shipping containers are used in different projects as well as sheltering and housing projects. It is a standard module which can be used as a basic module in the sheltering projects. Small modifications are sufficient, which helps it being a rapid application. In this paper a generative tool named Container PoDS which using shipping containers as basic module for post-disaster sheltering is introduced.
