The Vale de Moses yoga retreat is designed as a place for guests to relax and reconnect with nature. At the heart of the retreat is a simple sleeping pod that aims to meet basic needs while having a minimal impact on the environment. The design centers around the idea of what constitutes the simplest form of a sleeping space, leading to a functional and unobtrusive structure.

Architectural Organization

The sleeping pod features three columns that include key facilities: a shower, water closet, and storage. In between these columns is a compact sleeping area accommodating two people. The total area is just 13 square meters, which helps to limit disturbance to the natural landscape and enhances the experience of being close to nature.

Material Use

Local lumber forms the main structure of the pod. The solid framework rests on small concrete footings that follow regulations for building safety. This choice of materials helps the pod blend in with its surroundings while reducing the need for extensive excavation during construction. As a result, the overall energy used in building the pod is significantly decreased.

Sustainability Features

Key sustainability aspects are built into the pod's design. A water storage tank, water heater, and composting toilet sit beneath the floor, removing the need for traditional septic systems or external piping. This clever arrangement contributes positively to the environment. Guests can also use biodegradable soaps, allowing grey water to irrigate the landscape, further supporting the local ecosystem.

Natural Interaction

Large windows open towards the forest, creating views that connect the interior with the outside world. These windows let in plenty of daylight, setting a calming atmosphere for guests. Above the sleeping area, a skylight offers a glimpse of the night sky, adding an element of tranquility and inviting moments of reflection during their stay.

`
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.
