The ESPERE Yoga House is located in Oleiros, a place that embodies tranquility and nature. The design focuses on creating a harmonious space for yoga practice, allowing for connection between the building and its environment. A core objective of the design is to reflect the principles of flexibility and balance that are essential to yoga. The structure is intended to offer users a peaceful retreat where they can engage with both their surroundings and their inner selves.

Spatial Organization

The layout of the ESPERE Yoga House includes various public areas, ensuring the needs of different users are met. These areas comprise a reception, lobby-waiting area, office, storage, mini-cafeteria, changing rooms, bathrooms, lockers, and several yoga classrooms. The arrangement of these spaces allows for interaction while also accommodating individual practices. Clear pathways enhance ease of movement, creating an inviting environment for both social activity and personal reflection.

Innovative Eco-Friendly Systems

A key element of the design is the incorporation of eco-friendly systems that support sustainability. The water-saving system draws inspiration from traditional Damascene architecture and is tailored to the climate of Oleiros. It includes an air collector designed to use summer breezes for ventilation, while filters maintain air quality inside the building. Additionally, a rough inner wall supports sediment deposition, and a water storage system helps purify air, highlighting a thoughtful approach to environmental care.

Sustainable Energy and Resource Management

The facility also features a rainwater harvesting system, calculated according to local rainfall data, ensuring adequate water supply throughout the year. Grey water collected from bathrooms is filtered and reused for irrigation, promoting efficient resource management. Energy needs are addressed with a solar system that consists of 20 solar panels. These panels are chosen based on the building's size and expected energy consumption, thus making the project more energy-efficient and environmentally friendly.

Material Choices

Material selection is vital to the design and reinforces its sustainability goals. Support wood is used, particularly double-glazed, waterproofed redwood boards, which provide structural integrity and resistance to moisture. Hempcrete blocks are employed for their low environmental impact and ability to regulate temperature and humidity indoors. Oak wood is also incorporated, adding a natural aesthetic to the interior spaces and ensuring durability.

Architectural details contribute to creating an uplifting experience within the building. Large windows allow abundant natural light to flood the interiors, enhancing the sense of openness while fostering a relationship with the exterior landscape. The design encourages a tranquil atmosphere that promotes well-being and mindfulness, reflecting the underlying principles of yoga practice.

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.
