The modular housing module is located in the scenic countryside of Umbria, known for its rich medieval history. The design draws on the area's architectural traditions to merge modern living with local craftsmanship. It is intended to create a strong bond between residents and nature while fulfilling contemporary lifestyle requirements. The project features a two-level structure that encourages interaction among inhabitants and maximizes the use of natural light.

Design Concept

The structure consists of two levels connected by a wooden staircase that wraps around itself. This layout facilitates open spaces and easy movement, making it suitable for relaxing or socializing. The design pays close attention to the roof's orientation and the placement of large south-facing windows. These elements allow abundant natural light to flow throughout the interior, creating bright and welcoming spaces for residents.

Material Palette

The load-bearing elements are made of continuous XLAM (Cross Laminated Timber) panels, providing strength and structural integrity. Internal walls use raw earth infill panels, adding a touch of local character while maintaining sustainability. The ground floor is formed by a concrete slab, which provides stability. The roof utilizes CLT panels, along with insulation, a protective membrane, and photovoltaic tiles. The choice of these materials reflects a dedication to environmental responsibility and resource efficiency.

Passive Design Strategies

Energy efficiency is a key focus throughout the design. The building incorporates passive strategies that maximize comfort while minimizing energy consumption. The glass facade is engineered to capture sunlight, allowing solar warmth to enter while preventing excessive heat during hot days. A single-pitched roof enhances the collection of solar energy and provides shade to the windows, reducing the need for mechanical cooling during the warmer months.

Community Integration

The layout mirrors the structure of traditional medieval villages, positioning guest houses around a shared central square. This design fosters a sense of community, encouraging interactions among residents while offering private spaces for retreat. Shared areas are designated for wellness activities, including yoga and wine tasting, enhancing the overall residential experience.

Large windows and openings invite natural light into the spaces, linking the indoor areas with the outdoor environment and providing views of the surrounding landscape. This connectivity enriches the living experience, allowing residents to appreciate their picturesque setting while enjoying modern comforts.
