Earthen Vaults Embracing Nature in a Sustainable Winery Community

Project in-detail

Constructed with earthen walls and characterized by expansive vaulted forms, the design integrates seamlessly with the Umbrian landscape, creating a sustainable community space for wine production and tasting.
5 key facts about this project
01
Constructed using locally sourced earth for enhanced thermal regulation.
02
Ventilation is optimized through a unique vaulted form that mimics surrounding hills.
03
Community spaces incorporate winery bridges for direct engagement with wine production.
04
Design strategically positions living areas for maximum natural light and energy efficiency.
05
Outdoor areas feature a pool integrated with local vegetation for ecological harmony.

La Casa del Vino is located in Perugia, Italy, where it serves the purpose of enhancing organic wine production. Developed by the Tili Vini winery, it features a mix of residential spaces, a wine tasting area, and outdoor areas complete with a pool and greenery. The design focuses on sustainability and aims to create a close connection with the surrounding landscape by using traditional earth-based techniques.

Architectural Form and Function

The layout of the buildings relates directly to the natural sloping grounds. Vaulted shapes mimic the gentle curves of the nearby hills, contributing to both aesthetic appeal and improved airflow within the buildings. This connection fosters a sense of harmony between what is built and the natural environment, allowing for better ventilation and enhanced comfort inside.

Material Choices

Breathable earthen walls are a key component of the design. They help to manage humidity and create a comfortable indoor climate. Compared to common building materials, this choice lowers carbon emissions throughout the lifespan of the structures. The use of earth also allows the buildings to reflect the local colors and textures, blending well with the surrounding area.

Sustainable Practices

Sustainability is a major aspect of the overall design, with careful attention given to how spaces are oriented. Kitchens and bathrooms face north, while living rooms and bedrooms are positioned to the south. This arrangement maximizes the intake of natural light while reducing energy needs. Furthermore, the design makes use of cross ventilation, which provides efficient cooling without relying on mechanical systems, contributing to overall energy savings.

Integration with the Winery

A notable feature of La Casa del Vino is its inclusion of winery bridges connecting various parts of the complex. These pathways are not only practical but also create opportunities for visitors to engage with the wine-making process. This thoughtful layout promotes movement around the site, merging functionality with a sensory experience of the landscape.

The careful arrangement of these elements results in a design that encourages exploration and interaction with both the built and natural environments. Each detail enhances the user experience, contributing to the overall appeal of the project.
