The Horizon House is a contemporary residential project located in Santa Barbara, California. This architectural design emphasizes a seamless interaction with the surrounding landscape while maximizing the views of the Pacific Ocean and Santa Ynez Mountains. The layout features two primary levels organized to enhance usability and aesthetic appeal, prioritizing an open-plan living arrangement that encourages natural light and ventilation.

The project consists of distinct areas including a spacious living room, dining space, and kitchen on the upper level, all oriented toward expansive glass facades. This approach not only allows for unobstructed views but also creates a fluid connection to outdoor spaces, facilitating an engaging indoor-outdoor experience. The lower level is dedicated to private quarters, providing a retreat-like atmosphere for residents. Each guest room has direct access to landscaped gardens, connecting the interior with nature.

Sustainability is a key aspect of the design. The architect implemented passive solar principles, utilizing materials and configurations that reduce reliance on artificial heating and cooling systems. Features such as rainwater harvesting and native planting enhance ecological responsibility, reflecting a commitment to environmental stewardship.

Unique Design Approaches to Space and Interaction

The Horizon House employs innovative design strategies to differentiate itself from conventional residential projects. The use of retractable glass walls is a notable feature, as it allows the living area to extend outdoors seamlessly, providing flexibility for entertaining and relaxation while highlighting the coastal scenery. This versatility is complemented by carefully selected materials that resonate with the local context.

Reclaimed cedar wood serves as both an aesthetic and functional element, providing warm cladding that integrates the house with its natural surroundings. The use of structural steel enables large, unobstructed spaces and enhances the overall structural integrity. Additionally, the incorporation of natural stone in landscaping aligns with the regional geology, grounding the project in its locale.

Focus on Sustainability and Community Integration

A significant aspect of the Horizon House is its commitment to sustainability and community integration. By prioritizing materials that have low environmental impact and emphasizing local resources, the architecture fosters a sense of place that is reflective of the Santa Barbara environment. The design considers surrounding ecological systems, ensuring that the project supports local biodiversity and waterscapes.

Key architectural details such as a central atrium provide additional natural light and ventilation, promoting energy efficiency. The roof incorporates green elements that assist in temperature regulation while providing habitats for local wildlife. This thoughtful consideration of both design and environmental impact distinguishes the Horizon House from other residential projects.

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.
