5 key facts about this project
01
Photovoltaic array generates renewable energy on-site.
02

03
Operable windows facilitate natural ventilation throughout the space.
04
Thermal mass design maintains consistent indoor temperatures.
05
Courtyard design enhances daylight and interaction with nature.

ZEN HAVEN is a thoughtfully designed structure that balances sustainability and wellness. Located in a tranquil setting, it serves multiple functions such as a yoga studio, kitchen, and storage spaces. The design encourages interaction among users while promoting a sense of peace. The overall concept focuses on integrating natural elements, light, and open space, creating an environment that supports physical and mental well-being.

PRIMARY AXES AND SPATIAL ORGANIZATION

The layout of ZEN HAVEN relies on primary and secondary axes that guide movement through the building. These primary axes function as main pathways, linking various internal spaces. Secondary axes connect to outdoor areas, providing an easy transition from inside to outside. This design approach fosters interaction between users and their environment, enhancing the overall experience of the space.

SUSTAINABILITY STRATEGIES

A key feature of ZEN HAVEN is the photovoltaic array, which converts solar energy into electricity. This design decision prioritizes renewable energy, contributing to the building's efficiency. The courtyard plays an essential role as well, allowing ample natural light through well-placed windows and skylights. This design choice helps to minimize the need for artificial lighting during the day, making the space both functional and environmentally friendly.

WATER MANAGEMENT AND THERMAL COMFORT

Water management is addressed through a system that collects and purifies rainwater and gray water. This reduces overall water consumption, making the building more sustainable. In addition, the design includes a thermal mass system that absorbs solar energy. It effectively redistributes heat throughout the building, contributing to consistent warmth and comfort for occupants.

VENTILATION AND AIR QUALITY

Operable windows are located throughout the main space to enhance ventilation. This design feature allows fresh air to circulate, improving indoor air quality. The strategic placement of these windows not only extends comfort but emphasizes the building's connection to nature. Fresh breezes and natural light fill the interiors, creating a lively atmosphere from morning till dusk.

`
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.
