The Straw Bale Microhome is an architectural project designed to exemplify sustainable living in compact spaces. This microhome serves as a model for efficient living by utilizing eco-friendly materials and innovative design principles. It is situated in a suburban or rural landscape, carefully integrating into its environment while promoting minimal energy consumption.

The function of the Straw Bale Microhome revolves around providing essential living amenities within a confined footprint. Covering approximately 400 square feet, the layout consists of strategically organized areas that maximize usability and comfort. Key components include a kitchen, bathroom, and multi-functional living spaces that adapt to the needs of the occupants. Additionally, the design emphasizes natural light and ventilation, creating a conducive atmosphere for everyday living.

Architecture and Material Selection

The design employs a range of materials, foremost among them being locally sourced straw, which is utilized for the walls. This choice not only provides excellent insulation but also supports regional sustainability efforts. Complementary materials include natural wood finishes, PVC panels for system integration, and model panels for interior surfaces, creating a cohesive aesthetic while preserving structural integrity. Hydroponic systems are incorporated into the design, allowing residents to engage with sustainable food practices directly within their home.

The microhome is oriented to capitalize on southern solar exposure, thereby minimizing dependence on traditional heating systems and contributing to energy efficiency. The inclusion of retractable furniture elements illustrates an innovative approach to space management, allowing for versatile use of living areas without sacrificing comfort or function.

User-Centric Design Features

Several unique design approaches set the Straw Bale Microhome apart from conventional housing models. One of the most notable aspects is its focus on adaptability; features such as a retractable water tank and modular furniture enhance the living experience by ensuring that limited space does not translate to limited usability. Furthermore, a dedicated overhead storage loft provides additional room without encroaching on the living area, underscoring the microhome's design efficiency.

Natural ventilation is a critical feature, created through strategically placed openings that work in tandem with a passive cooling system. This approach ensures that the interior climate remains comfortable throughout varying seasonal conditions without reliance on mechanical air conditioning.

Sustainability is also a pivotal aspect of the design. The integration of a water collection system further emphasizes this ethos, allowing for harvesting rainwater, thereby reducing reliance on municipal water supplies. The hydroponic gardening systems integrated into the design not only maximize the use of space but also promote self-sufficiency in food production.

For a more detailed exploration of the Straw Bale Microhome, including its architectural plans, sections, designs, and underlying architectural ideas, readers are encouraged to delve into the project presentation for comprehensive insights. This microhome exemplifies the potential of sustainable architecture to create functional, livable spaces that resonate with contemporary environmental needs.

Design a new small-scale home concept in the 10th edition of MICROHOME — 100,000 € prize + construction

Competition organisers

The 10th edition of the MICROHOME architecture competition invites architects and designers from around the world to explore the possibilities of compact, sustainable living. Hosted by Buildner in collaboration with Kingspan and Hapi Homes, this special edition challenges participants to design an off-grid, modular microhome for a young professional couple, with a maximum floor area of 25 m². Designs should prioritize innovation, efficiency, and real-world feasibility. 

A total prize fund of 100,000 € will be awarded, including three main prizes, the Kingspan Award, and the Hapi Homes Award, which will grant 15,000 € and lead to the construction of the selected design. The final registration deadline is September 25, 2025, and winners will be announced on Decebmer 9, 2025. For full competition details and submission guidelines, visit microhome.info.
