Brick walls and a geothermal system work together to create a sustainable environment that captures rainwater while providing guests a serene stay among the vineyards.
5 key facts about this project
01
Brick walls integrate traditional craftsmanship with modern design aesthetics.
02
The design captures rainwater for reuse, enhancing sustainability.
03
Private spaces are located underground to utilize geothermal energy.
04
Open galleries promote natural airflow throughout the pavilions.
05
A tasting house serves as a community hub for local wine experiences.

The Tili Wine Italy Guest Eco-Homes project is located in a rural area known for its wine production. It consists of six pavilions arranged around a central square, which promotes interaction among visitors while allowing for personal space. The design prioritizes sustainability and aims to connect with the surrounding environment, creating a space where people can experience and appreciate local viticulture.

Rainwater Management

Effective rainwater management is a key focus of the design. Each pavilion is surrounded by open galleries that capture rainwater from the roofs. This collected water is directed to an underground system where it is treated and made ready for reuse. This not only reduces reliance on outside water sources but also promotes self-sufficiency within the project.

Air Circulation

Natural airflow is another important aspect of the design. The pavilions are slightly elevated, allowing for expansive views of the surrounding fields. The open layout facilitates the movement of air, which enhances comfort inside the spaces. This design works to utilize breezes effectively, reducing the need for mechanical cooling and heating.

Geothermal Principles

The placement of private spaces in the subterranean level takes advantage of the earth’s natural thermal properties. By doing this, the design helps maintain comfortable temperatures throughout the year while lowering energy demands. The surrounding open galleries support airflow and protect inhabitants from harsh weather.

Architectural Expression

The project blends traditional and modern elements. Traditional brick walls contrast with contemporary stainless steel roofs. This combination reflects local craftsmanship while meeting the needs of visitors. Each pavilion has its own character but contributes to a unified aesthetic. This thoughtful design emphasizes the relationship between the buildings, the landscape, and the culture of wine production.

The material choices and architectural forms invite visitors to connect with the area’s heritage and current practices in winemaking, grounding them in the experience of rustic yet refined living.

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.
