H-eva is a prefabricated, self-sufficient cabin designed by Bordeaux-based firm A6A (Atelier 6 Architecture) and manufactured by My Little Loft in Sainte-Foy-la-Grande, France. The project is an exploration of micro-architecture that blends modern comfort with traditional materials, emphasizing a connection to the landscape and the awareness of daily needs. The cabin is manufactured in a workshop and transported to its final location on a flatbed truck, installed with a crane. This approach minimizes on-site impact and allows the cabin to be moved, leaving the land reversible for other uses.

The exterior is clad in charred Douglas fir boards sourced from local, controlled forests. This shou sugi ban technique not only protects the wood from insects and weathering but also gives the cabin a deep black finish, reminiscent of traditional regional woodcutters' huts.

Autonomous systems: H-eva is designed for self-sufficiency, with several integrated systems to reduce its reliance on external connections. Energy: A wood stove provides heating, while photovoltaic panels generate electricity. Water: Water is filtered through a micro wastewater treatment system integrated into the structure, and low-flow faucets minimize usage. Waste: The cabin utilizes a dry toilet system that operates without water waste or pollution.

The interior offers a contrast between light and dark, with natural wood paneling. The design is open to the landscape, creating an immersive spatial experience. The modular design allows for elements to be connected to create larger living spaces. Various layouts and sizes, ranging from 16 to 38 m², are available to suit different uses and settings.
