Charred Wooden Shingles and Local Stone Create a Sustainable Shelter for Trekkers

Project in-detail

Combining charred wooden shingles with local stone, the design establishes a resilient structure that efficiently provides shelter and accommodation for trekkers in a challenging mountainous environment.
5 key facts about this project
01
Utilizes locally sourced stone to enhance thermal mass and climate adaptability.
02
Incorporates charred wooden shingles for improved durability and fire resistance.
03
Features large glazed facades designed for optimal solar gain and panoramic views.
04
Includes flexible interior spaces that can be easily adapted for different uses.
05
Employs a bent A-frame design to maximize structural stability in harsh weather conditions.
The "House of Sun" is an architectural project situated in a mountainous region, designed to cater to the needs of trekkers. The primary function of this structure is to provide shelter and accommodation while integrating sustainable practices that respond to the local climate and environment. The design leverages passive solar heating and strategically planned spaces to enhance comfort and efficiency for its occupants.

The project employs a distinctive massing approach, with a non-linear configuration that maximizes solar exposure, particularly on the south-facing orientation. This layout not only serves aesthetic purposes but also optimizes natural heating throughout the day, benefiting from the thermal properties of the materials used. The architecture emphasizes the use of local resources, incorporating stone and timber as primary materials to create a robust and contextually relevant structure.

Sustainable materials and practices characterize the project. The exterior is clad in locally sourced stone, providing both durability and thermal mass, which helps regulate indoor temperatures. The incorporation of timber in the roof and interior elements introduces warmth while ensuring structural integrity. Expansive glass windows facilitate significant daylight penetration and offer panoramic views of the surrounding landscape, while advanced glazing technologies contribute to thermal efficiency.

A unique aspect of the "House of Sun" design is its focus on adaptable interior spaces. The layout promotes flexibility, allowing areas to serve multiple functions, whether for private stays or communal meals. Buffer spaces act as transitional zones, improving air quality and moderating temperature fluctuations between the outside environment and the interior.

Another notable feature is the emphasis on thermal massing, where the stone walls are designed to absorb heat during daylight and release it at night. This passive design strategy minimizes reliance on mechanical heating, aligning with the project’s sustainability goals. Natural ventilation is also facilitated through the careful placement of openings, enhancing airflow and maintaining a comfortable interior climate.

The "House of Sun" distinguishes itself through its thoughtful integration of local materiality, sustainable design practices, and functionality tailored to its users' needs. This architecture project not only addresses the immediate requirements of shelter but also creates an environment that respects and interacts harmoniously with its natural surroundings.

For a deeper understanding of the "House of Sun," consider exploring the architectural plans, sections, and design choices that contribute to its unique identity. These elements reflect the project’s comprehensive approach to architecture and sustainable living in a challenging environment.

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.
