Ashborn House is an architectural project designed to meet the challenges posed by climate change through a thoughtful integration of sustainable practices and innovative design. Located in a landscape shaped by volcanic activity, the project focuses on creating a microhome that is functional, resilient, and environmentally responsible. Covering an area of approximately 25 m², the house incorporates modular features that allow for flexible use of space while fostering a close relationship with the surrounding natural environment.

Space Organization and Functionality

The architectural composition of Ashborn House consists of three distinct functional blocks: a communal living area, a kitchen and gathering space, and a private sleeping loft. This organization facilitates an efficient spatial flow, promoting interaction among residents while also allowing for personal privacy. Large windows are strategically placed to maximize natural light and views, enhancing the indoor-outdoor connection that is fundamental to the dwelling’s design philosophy. The roof, sloping to aid in natural ventilation, contributes to maintaining a comfortable internal atmosphere while echoing the site's topographical features.

Sustainable Design Approaches

What sets Ashborn House apart from conventional residential designs is its commitment to sustainability through materials and technologies that reduce environmental impact. The primary structure utilizes concrete made from locally sourced aggregates, minimizing carbon emissions linked to transportation and production. Internal wooden elements contribute warmth and aesthetic appeal, while also leveraging renewable resources. The integration of biophilic design, including living walls, enhances biodiversity and improves indoor air quality.

The project incorporates advanced technologies such as solar panels for renewable energy generation and geothermal systems that take advantage of the site's geological characteristics for climate control. Rainwater harvesting systems are integrated to efficiently manage water resources, showcasing a comprehensive approach to sustainability. Each aspect of the architectural design reflects a commitment to creating a resilient living space that actively engages with its environment.

Integration with the Natural Landscape

The siting of Ashborn House emphasizes a deep respect for its natural context. The layout carefully considers the prevailing winds, sunlight access, and topographical features to enhance both energy efficiency and quality of life. By creating a residence that aligns with the ecological realities of the location, the project serves as a model for future sustainable housing initiatives.

Ashborn House exemplifies a holistic architectural approach that prioritizes environmental responsibility while providing a comfortable and functional living space.

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.
