Straw-Bale Walls Create Thermal Mass For Sustainable Coastal Living

Project in-detail

Employing straw-bale construction to achieve superior thermal mass, this residence integrates seamlessly with its coastal landscape while providing a sustainable living environment.
5 key facts about this project
01
Utilizes locally sourced straw-bale construction for enhanced insulation and sustainability.
02
Features a bent A-frame design that integrates with the natural slope of the site.
03
Incorporates large windows to maximize natural light and views of the coastal landscape.
04
Employs modular design elements for flexible use of interior spaces.
05
Utilizes regional materials such as wood and metal to reduce environmental impact.
The Mass Straw House is an architectural project that utilizes locally sourced straw as its primary building material, exemplifying a sustainable approach to design and construction. Situated within a rocky coastal landscape, the project integrates seamlessly with its environment while addressing contemporary ecological concerns. The structure not only functions as a residential space but also serves as a model for eco-friendly architecture, demonstrating the viability of alternative materials in modern construction.

The architectural design emphasizes ‘thickness’ as both a structural and conceptual element. Rather than viewing thickness as a limitation, the design harnesses it to enhance thermal performance and acoustic insulation. The use of straw bales forms thick walls, providing superior insulation which is crucial in the northern climate where the house is located. The arrangement of spaces within the house reflects a thoughtful approach, with a linear configuration that adapts to the terrain while ensuring functional flow between living areas.

Innovative Material Application

What sets the Mass Straw House apart from other projects is its commitment to sustainable building practices through innovative material application. By opting for straw, a renewable resource that is often considered waste, the project significantly reduces its ecological footprint. The structural integrity of the house is reinforced using wood beams and cast concrete elements, which provide necessary support while being complemented by the organic feel of the interiors.

The roof features corrugated metal sheets, creating a juxtaposition against the soft, natural appearance of the straw. This design choice enhances the visual interest of the structure while ensuring durability against weather elements. Furthermore, the incorporation of large windows and skylights maximizes natural light and ventilation, creating a comfortable and inviting living environment.

Functionality and Space Efficiency

The Mass Straw House is designed with flexibility and efficiency in mind, catering to the dynamic needs of its occupants. Internally, spaces are organized to promote versatile use, with areas designated for living, dining, and multifunctional purposes. The integration of built-in furnishings allows for optimal space utilization, making the most of the available square footage while maintaining an open feel.

The layout encourages interaction with the natural surroundings, utilizing strategic placements to frame views of the landscape. This connection to the exterior reflects a commitment to enhancing the occupants' wellbeing and fostering a sense of inclusivity with the environment.

For those interested in further exploring the architecture and design of the Mass Straw House, a detailed review of architectural plans, sections, and design ideas will provide deeper insights into the unique elements that define this project.

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.
