### Overview

The Stone Barn Meditation Camp is situated alongside a river, enveloped by a natural landscape. The intent of the project is to create an environment that promotes mindfulness and meditation by integrating modern architectural approaches with the historical fabric of an existing stone barn. This retreat is designed to foster relaxation and a close connection to nature, achieving a balance between heritage and contemporary functionality.

### Spatial Strategy and Architectural Integration

The design thoughtfully positions the new structures in relation to the existing barn to maximize views and interaction with the surrounding landscape. The trapezoidal roofs of the new elements are oriented to rise towards the sky, which reflects the meditative focus of the facility. Large windows throughout the elevations enhance the visual connection to the outdoors while facilitating natural light penetration, essential for creating an atmosphere that encourages contemplation. Interior spaces, including the meditation hall, feature a high ceiling with a central skylight, establishing a sense of openness and connection to the sky above.

### Materiality and Sustainability

The material selection plays a significant role in articulating the project's ethos. The existing stone barn utilizes locally-sourced stone, which anchors the design in its historical context, while the new wooden structures add warmth and a tactile quality that resonates with the natural environment. Extensive glazing elements not only optimize views but also enhance the emotional impact of the interior spaces. Additionally, sustainable design principles are incorporated; passive solar strategies and natural materials reduce energy consumption and minimize disturbance to the site's ecological balance, preserving the existing vegetation.

Unique architectural elements, such as the octagonal meditation hall, exemplify the project's focus on creating specialized spaces that cater to spiritual practices. By fostering a harmonious relationship between the architectural intervention and the site’s natural features, the design emphasizes both functionality and a sense of serenity for its users.

`
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.
