5 key facts about this project
01
Trapezoidal shape maximizes natural light and views.
02

The design presents a trapezoidal structure set within a lush green landscape, focusing on harmony between built form and nature. It serves as a meditative space, raising users above the ground to provide wide views of the surroundings. The design emphasizes transparency and sustainability, fostering an immersive experience that encourages interaction with the outdoors while incorporating energy-efficient technologies.

Structural Design

The building’s trapezoidal shape is oriented to allow maximum natural light and optimize views. The roof slopes gently towards the north, supporting nine photovoltaic panels. These panels capture solar energy, achieving a peak power output of 3.6 kWh. The power generated is converted by an inverter and stored in a 14 kWh battery located beneath the platform. This setup enhances not only the aesthetic but also emphasizes sustainability and energy efficiency.

Materials and Construction

Durability and environmental performance shape the building's construction. Glued laminated timber forms the framework, providing strength and flexibility. High-density rock wool insulation is used throughout to improve thermal performance, while marine plywood is chosen for its durability outdoors. The roof and platform construction includes a sandwich design that ensures stability, complemented by finishing edges in anthracite or coffee-colored aluminum. The selection of materials contributes to the building's longevity and visual harmony.

Interior Experience

Inside, the layout comfortably accommodates six to seven users, with mats available for relaxation or meditation. At the center, an altar features a heated surface powered by an electric system, allowing for the use of essential oils. Cylindrical lamps placed above the altar cast soft light, enhancing the atmosphere and inviting a sensory experience for those within the space.

Natural Integration

Rainwater management has been thoughtfully incorporated into the design. Collected rainwater is directed to a tank, where a spray jet fountain powered by solar energy prevents stagnation. This feature adds both visual and auditory elements to the environment, enriching the experience. Excess water is directed into a lower tank, allowing it to disperse into the ground, supporting the local ecosystem.

The design features a simple wooden staircase, paired with a metal handrail, providing access to the upper platform. This element reflects the project’s focus on clarity and functionality, completing the overall experience of the space.

`
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.
