### Overview

The Porta-Habitat initiative addresses the critical housing needs of populations displaced by natural disasters, particularly in light of increasing climate change impacts. The project is situated in areas prone to such events and is designed to provide mobile, adaptable living solutions that prioritize community engagement and sustainability. The goal is to create effective emergency housing options that facilitate resilience and quicker recovery for affected individuals and communities.

### Modular and Adaptive Design

The Porta-Habitat's design features an accordion-like structure that enables rapid deployment and reconfiguration based on the needs of its occupants. This modular approach allows for compact transport and expansive living configurations, supporting varying occupancy levels. Shared communal spaces are integrated into the design, fostering social interaction and collaboration among residents. This emphasis on communal environments aims to strengthen social ties and support networks during times of crisis.

### Sustainable Material Selection

The project incorporates a diverse range of materials chosen for their durability, sustainability, and functional properties. Key components include solar panels for renewable energy generation, Kingspan® insulated panels for thermal efficiency, and a robust steel frame to withstand environmental stresses. Transparent ETFE membranes enhance natural lighting while promoting aesthetic values. Additional use of plywood and aluminum ensures the structural integrity and comfort of the interiors. This thoughtful material palette not only meets practical needs but also contributes positively to the overall user experience within the living spaces.

The MICROHOME 10 competition invites participants to submit visionary designs for off-grid, modular microhomes that push the limits of sustainable, small-scale living. Organised by Buildner in partnership with Kingspan and Hapi Homes, this tenth edition sets the challenge of designing a dwelling for two people within a maximum floor area of 25 m², encouraging bold solutions adaptable to any urban or rural location. The competition continues Buildner’s mission to foster innovative approaches to compact, energy-efficient housing that can address pressing global challenges.

This year’s edition offers a generous total prize fund of €100,000, including the Kingspan Award for designs that integrate high-performance Kingspan products and the Hapi Homes Award for a project selected for real-world construction. In addition to cash prizes, the winners gain international exposure through Buildner’s media partnerships, publications, and a dedicated MICROHOME magazine, further amplifying their ideas to the wider architectural community.
