The Sand Tower is situated in a desert landscape and is designed to blend with its surroundings. Drawing inspiration from traditional forts, the tower resembles a fort made of sand blocks, connecting it visually and contextually to the environment. Its purpose is more than just to observe; it enables exploration and contemplation of both the land and the sky.

Conceptual Framework

The design is influenced by the astrolabe, an ancient device used for navigation and astronomical observations. This inspiration is evident in the structure’s geometry, which features two interlocking circles. This design allows for optimal views from the ramp and terraces, encouraging users to engage with the vast desert and the sky above, enhancing the connection to the natural world.

Design Features

A continuous, shallow ramp leads up to a higher platform, offering 360-degree views that invite users to take in the landscape from all angles. Inside, a shaded atrium offers a place for rest and contemplation, responsive to the desert’s light and heat. This aspect encourages meaningful engagement with the environment while providing comfort from the elements.

Material Considerations

The materials chosen for the Sand Tower reflect a focus on sustainability. The walls are made of interlocking recycled plastic modules, providing both strength and a reduced environmental footprint. These walls sit on concrete trenches for stability. Wood plastic composite beams connect the walls and form the ground floor and ramps, further emphasizing the project’s commitment to environmentally friendly design.

Visual and Aesthetic Elements

The structure features an interlocking pattern of sand blocks that visually resemble a group of flamingos. This design choice echoes natural forms, with three simple curves and two vertical lines that invoke the elegance of these birds. The facade’s layered textures contribute to a dynamic play of light and shadow, inviting closer inspection and highlighting the building’s thoughtful detailing.

`
Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
