The Sanctuary is an architectural project located within the serene landscape of Blue Clay Country in Latvia. This retreat and spa is designed to facilitate relaxation and introspection, offering a harmonious interaction between the built environment and the surrounding natural world. The project focuses on three guiding principles: Primitive, Separation, and Nature, which work together to create a unique atmosphere that encourages wellness and mindfulness.

The overall design integrates various spaces, including spa facilities and a guest house, which cater to visitors seeking rejuvenation and tranquility. The project emphasizes sensory experiences, reflecting a commitment to fostering an environment conducive to connection and personal reflection. Notably, the layout has been carefully structured to promote exploration while providing areas of privacy for guests.

Spatial Organization and Function

One of the defining characteristics of The Sanctuary is its spatial organization, which allows for a seamless flow between different areas of the retreat. The spa facilities are designed as cave-like structures that invite visitors to relax and unwind. Elements such as elongated corridors create a perception of time dilation, enhancing the reflective experience.

The guest house is designed to feel like a home away from home, imbued with warmth and hospitality. It offers intimate accommodations that encourage guests to embrace the serene environment. Further, outdoor spaces such as gardens and terraces provide opportunities for engagement with nature, reinforcing the therapeutic aspects of the design.

Unique Materiality and Sustainability

A significant feature of The Sanctuary is its thoughtful selection of materials. The use of concrete provides structural integrity while ensuring temperature regulation. Glass elements are incorporated extensively to maximize natural light and offer panoramic views of the landscape. Wood is prominently featured, creating warmth and resonance with the environment. Natural stone is used for pathways, enhancing the connection between the architecture and the earth.

Moreover, sustainability is a core principle of the project. The design incorporates systems for rainwater collection, solar energy utilization, and organic food production through onsite gardens. This commitment to sustainable practices reflects a modern approach to architecture that prioritizes ecological responsibility while enriching the user experience.

The Sanctuary transcends conventional retreat designs through its holistic approach. By uniting architecture with the natural landscape, the project creates a unique setting that promotes well-being and a profound connection to nature. For those interested in exploring the detailed architectural plans, sections, and designs of this project, reviewing these elements will provide further insight into its innovative architectural ideas.

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.
