**Overview and Intent**
Located in a context conducive to sustainable living, "Heat-Wind-Shelter" reflects a commitment to environmentally responsive design. This residential project aims to create a harmonious relationship between the built environment and natural surroundings while promoting energy efficiency and comfort. The architectural strategy incorporates flexible spatial configurations that facilitate interaction with elements such as sunlight and wind, thereby addressing contemporary environmental challenges.

**Spatial Organization and Interaction**
The layout consists of an open-plan design that emphasizes adaptability, allowing inhabitants to tailor their living spaces according to their needs. Features such as strategically placed large windows enhance natural light and create visual connectivity with outdoor areas, contributing to improved air quality and fostering a sense of well-being. Communal spaces, including gardens and terraces, are integrated to encourage social interaction among residents, reinforcing community ties.

**Materiality and Environmental Considerations**
The project employs a deliberate selection of materials designed to harmonize with its ecological context. Extensive use of glass facilitates transparency and a strong connection to the outdoors, while wooden slats provide essential shading and ventilation. Concrete elements provide durability and texture, grounding the structure in its environment. The façade incorporates a woven pattern of wooden slats to mitigate solar gain, enhancing passive cooling strategies and reducing the need for mechanical systems. The integration of local flora in landscaping supports biodiversity and aligns with biophilic design principles. Furthermore, the structure’s passive solar management features and strategic wind channels ensure resilience against varying climate conditions, promoting a sustainable living environment.

Competition organisers

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.
