RHU Structure

The RHU Structure is a sustainable shelter that lasts throughout the duration of displacement and beyond its basic purpose as emergency shelter.

Incremental approach

The reliable steel framework can be clad with tarpaulin in an emergency and upgraded with local material overtime.

User led process

Residents can apply their expertise and building traditions, which fosters independence, creates livelihood opportunities and control.


Culturally and climatically adaptable, it may be combined with a range of materials and techniques in different types of responses and contexts.

The RHU Structure was developed for contexts where local building materials can be obtained. The metal frame can be wrapped in standard sized tarpaulin for deployment in emergency response, while the walls and roof may be upgraded with locally sourced building materials and attached to the frame with various techniques.

The lifespan of the RHU Structure is strengthened by the incremental approach to build upon multiple shelter usages according to local climate conditions and cultural traits. By embracing local contexts, resident families and NGOs can adapt the RHU Structure to their specific needs over time, through multiple project cycles and in the duration of displacement.
