The Tutu Mutu Cabin is a private retreat located in a quiet countryside area, designed for relaxation and a connection to the outdoors. Its minimalistic form centers around practical living while highlighting the importance of the surrounding landscape. The building spans two levels, featuring an open layout that allows for easy movement through various spaces while creating a sense of intimacy.

Design Concept

The design reflects a focus on creating different environments for various activities related to relaxation. On the first floor, the living area and kitchen are located in close proximity, allowing for easy meal preparation and social interaction. A spacious terrace extends the interior space outdoors, with a hot tub positioned to provide a calming view of nature.

Spatial Configuration

Efficient use of space is seen throughout the cabin. Essential features are carefully arranged in order to maintain a clean and organized atmosphere. A staircase near the entrance leads to the second floor, which holds a private bedroom and bathroom. These spaces are oriented towards the landscape, offering wide views that enhance the overall living experience. Skylights above the bed and shower serve as clever design elements, creating opportunities for stargazing and bringing natural light into the bathing space.

Sustainability Measures

Sustainability plays a key role in this design. The cabin incorporates a rainwater harvesting system, allowing for responsible water management. Collected rainwater is stored in an underground container for domestic use. Ozone filters are employed to purify the water, while reverse osmosis systems provide clean drinking water. The hot tub can also collect rainwater, further supporting eco-friendly practices.

Materiality

Constructed with traditional timber framing, the cabin is insulated with Rockwool to enhance energy efficiency. Windows are triple-glazed to offer good thermal performance while reducing energy loss. These materials come together to create a comfortable living environment that complements the minimalistic design.

The Tutu Mutu Cabin serves as a thoughtful example of how architecture can foster a connection with nature while providing comfort. Its careful consideration of light and space creates an inviting atmosphere, reflecting the beauty of the surrounding landscape.

`
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.
