Constructed with a core of Eucalyptus and featuring tatami flooring, the retreat creates a harmonious environment for healing while integrating sustainable practices and a connection to nature.
5 key facts about this project
01
Core constructed from locally sourced Eucalyptus wood.
02
Tatami mats enhance acoustics and provide thermal insulation.
03
Roji garden introduces culinary and therapeutic plants along the path.
04
Adjustable wooden shutters optimize light and thermal control.
05
Water conservation systems utilize rainwater and gray water for irrigation.

The design is located in a calm setting, aiming to provide a space for healing and reflection. It blends with its surroundings while focusing on comfort and practicality. The concept draws on ideas from Taoism and Zen, creating an environment that encourages peace and well-being through thoughtful spatial arrangement and a strong connection with nature.

Core Concept

Central to the design is the Core, or Energy and Movement Center, which serves both structural and functional purposes. This element organizes essential services and spaces, allowing users to move comfortably between treatment and relaxation areas. By focusing on stability and balance, the Core plays an important role in the overall layout, facilitating a smooth flow for various activities.

Roji and Healing Spaces

The roji functions as a vital promenade leading visitors from the outside world into the retreat’s inner spaces. This thoughtfully designed pathway introduces visitors to a variety of culinary and therapeutic plants, enriching their sensory experience and promoting a holistic view of well-being. The tranquil feeling created by the roji prepares individuals for a more intimate experience in the treatment room, where the atmosphere encourages introspection and healing.

Materiality and Structure

Materials used in the design reflect a commitment to sustainability and connection to the environment. Eucalyptus wood is chosen for the core, providing warmth and durability, while tatami mats made of compressed rice straw enhance sound quality and temperature control. The building features large wooden beams that use leverage principles, maximizing space while minimizing waste. Charred pine wood is also included in external elements for added strength and visual interest.

Sustainable Practices

Attention to sustainable practices is evident throughout the project. Adjustable wooden shutters offer effective control of sunlight, while cross-ventilation methods improve indoor air quality. Water conservation systems allow for the collection and reuse of rainwater and gray water. This careful planning supports ecological responsibility and aligns with the design's goal of creating a self-sufficient environment.

In the treatment room, tatami mats connect the interior to traditional practices. They help establish a calm atmosphere that enhances the healing process, creating a setting where visitors can find comfort and relaxation.

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.
