Charred Wooden Shingles and Elevated Steel Frame Define a Sustainable Microhouse Solution

Project in-detail

Constructed with charred wooden shingles and a resilient steel frame, this microhouse elevates sustainable living while providing adaptable, multifunctional space in a compact footprint.
5 key facts about this project
01
Constructed with charred wooden shingles for enhanced durability and aesthetic appeal.
02
Utilizes cross-laminated timber panels to provide structural strength and thermal efficiency.
03
Features a bent A-frame design to optimize interior space and natural light.
04
Incorporates an integrated rainwater harvesting system for resource efficiency.
05
Elevated construction mitigates flood risk while maintaining landscape connectivity.

The Terra Refuge is a microhouse designed to provide efficient living solutions while maintaining a strong connection to the environment. This project emphasizes sustainability and adaptability, making it suitable for various geographic contexts—urban and rural alike. By focusing on resource efficiency and ecological resilience, this architectural design stands out in the contemporary housing landscape.

Space within the Terra Refuge is optimized through a modular layout that enables diverse functions. The microhouse features a hexagonal shape, allowing for maximum interior space efficiency. Each area is designated for specific uses, including a multi-functional living area, kitchenette, social spaces, and private sleeping quarters. Large glass windows are strategically placed to enhance natural light and offer views of the surrounding landscape, effectively connecting the inhabitants with their environment.

Innovative Design Features

One of the unique aspects of the Terra Refuge is its elevation strategy, designed to mitigate risks associated with flooding and harsh weather conditions. This elevates the structure above potential water levels while integrating seamlessly with the landscape. Sustainability is further promoted through the use of eco-friendly materials, including steel for the structural framework and laminated wood for the interior finishes. These choices balance durability with aesthetic warmth.

The microhouse employs a range of energy-efficient technologies. Solar panels and wind turbines are incorporated into the design, providing renewable energy and reducing reliance on conventional power sources. Additionally, a sophisticated rainwater harvesting system collects and stores water, enhancing the household's sustainability and promoting responsible resource management.

Architectural Considerations

Attention to detail is evident in the architectural aspects of the Terra Refuge. The design prioritizes spaciousness, with high ceilings that contribute to a feeling of openness. Fixed wooden panels and folding doors serve dual purposes, providing structural stability while allowing flexible usage of internal spaces. The integration of natural materials complements the surrounding environment, fostering a seamless transition between indoors and outdoors.

With its adaptable design and eco-conscious features, the Terra Refuge represents a modern approach to housing that prioritizes functionality without sacrificing aesthetic quality.

The Mujassam Watan Urban Sculpture Challenge invites architects and designers to create iconic public sculptures for one of two sites in Saudi Arabia: Abu Hadriyah Road or the Tharwa Sea Front in Al-Khobar. Proposals should reflect Saudi identity, culture, and future aspirations.

`

The Mujassam Watan Urban Sculpture Challenge is an international architecture and design competition inviting creatives to shape the future of Saudi Arabia’s public spaces. With a total prize fund of €50,000, the competition calls for sculptural proposals that merge cultural symbolism with innovative design, offering participants a chance to see their concepts brought to life in a rapidly transforming national context.

Organised by Buildner in partnership with the Mujassam Watan Initiative, the challenge focuses on two prominent locations: Abu Hadriyah Road, a major highway and gateway into the Eastern Province, and the Tharwa Sea Front in Al-Khobar, a pedestrian-focused waterfront district. Designers must select one site and develop a sculpture that engages with its surroundings—whether addressing the fast-paced dynamism of a transit corridor or creating moments of interaction along a coastal promenade.

Proposals should be bold, site-specific, and rooted in narrative—drawing on themes such as heritage, national identity, transformation, and dialogue. Environmental responsiveness, material durability, and feasibility are strongly encouraged, as winning projects may be selected for actual construction.

Each submission must include four A2 landscape presentation boards, a cover image, and a written project description. The competition is open to professionals and students alike, working individually or in teams of up to four people. No professional license is required.

Registration is open until July 24, 2025, with final submissions due by August 27, 2025. Winners will be announced on October 1, 2025.
