The Invisible Tea House is an architectural intervention that connects with the historical significance of a stone barn, a key part of the area’s tea-making tradition. The design seeks to honor the barn's character while providing practical spaces for visitors to experience tea culture. The project's main aim is to retain the original proportions of the barn, allowing it to fit comfortably within the landscape.

Design Concept and Structure

At the heart of the design is the intent to enhance the barn's usability while respecting its rich history. By keeping the original dimensions, the building remains tied to its environment. The design introduces an extension that creates a spacious open living room and maintains the relationship with the existing barn, emphasizing continuity between old and new.

Material Selection

The choice of materials is crucial in preserving the project’s visual appeal and function. The design plans to replace the old timber-clad gables with charred wood cladding, utilizing a traditional Japanese technique called Shou Sugi Ban. This process strengthens the wood and creates a distinctive textured finish that contrasts with the rough stone walls. The charred wood adds character while also being resistant to weather and pests.

Integration with Nature

Large glass openings in the extension establish a strong connection between the interior and the natural surroundings. These features allow plenty of natural light into the living areas, creating a warm and welcoming space. The polished aluminum used for the extension's facade helps it to blend with the existing barn. Its reflective surface engages with the landscape, reinforcing the integration of old and new.

One notable design detail is the careful alignment of the extension with the barn. This relationship allows each structure to maintain its own identity while still feeling connected. This thoughtful arrangement encourages visitors to engage with both the history of the barn and the ongoing tradition of tea making.

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.
