Rammed earth forms create a drought-resilient community with integrated rainwater gardens, designed to foster social interaction and sustainable living.
5 key facts about this project
01
Rammed earth serves as the primary structural material, enhancing thermal mass and energy efficiency.
02
Rainwater collection systems channel water for rooftop vegetable gardening, promoting sustainability.
03
Communal areas include gardens and a fire pit, designed to encourage social interaction among residents.
04
Large openings on the northern facade provide panoramic views while minimizing heat gain.
05
Recycled bricks from an existing building are integrated into the new structure, supporting material reuse.

The Tilli Vinehouses project is located in the Perugia region, an area facing significant environmental challenges, particularly due to drought. This design aims to create a connection between the buildings and the surrounding landscape, emphasizing sustainability and practicality. The concept focuses on balancing natural elements with the needs of the residents, while also employing strategies that reduce energy use and encourage a sustainable way of living.

Design Concept

At the heart of the design are four key elements necessary for growing organic vines: earth, water, sunshine, and people. These elements are integrated into the structure, demonstrating a commitment to organic principles in a modern context. The use of rammed earth connects the buildings to the soil, while recycled bricks from an old house illustrate the importance of reusing materials. This thoughtful approach promotes environmental responsibility.

Water Management

Water management is a vital aspect of the design. A rainwater collection system gathers water from the roof and stores it in a tank. This collected water can be used for growing vegetables on the rooftop garden. This method supports water conservation efforts and promotes local food production. It also strengthens the connection between residents and their environment.

Spatial Arrangement

The layout of the spaces within the development balances private and shared areas. Communal features include gardens, a swimming pool, and a fire pit, which encourage interaction among residents. Additionally, a restaurant is located at the entrance to serve both residents and visitors, highlighting the community-oriented nature of the design.

Architectural Details

The design incorporates specific elements that respond to the local climate. To minimize direct sunlight, a secondary roof structure has strategic openings made with vine barrels. This allows light and air to enter the living spaces while reducing the dependence on cooling systems. The overall form of the buildings creates a visual link with the surrounding vineyards and hills, resulting in an approachable design that fits well within its context.

The Next House: USA — A Global Call to Reimagine the American Suburb

`
Competition organisers

Buildner is launching The Next House: USA, a global architecture competition that challenges architects, designers, and thinkers to reimagine the American suburban home for the 21st century. For decades, the suburban house has symbolized comfort and stability, but today it often reflects excess, isolation, and environmental strain. This competition asks: how can the American home evolve to address climate urgency, economic pressures, and shifting social values?

Participants are tasked with designing a prototype home of no more than 1,500 sq ft (≈140 m²) for a household of two adults and one child. The design should be compact yet generous, adaptable, sustainable, affordable, and replicable across diverse U.S. contexts. More than a design exercise, the competition aims to spark a conversation about how homes can support healthier, smarter, and more connected communities.

The total prize fund is $20,000 USD. The final registration deadline is May 20, 2026, and winners will be announced on September 22, 2026. The Next House: USA invites architects, students, and visionaries worldwide to redefine what the American home means today—and what it should mean tomorrow.
