Designed by A69 Architectural Studio, this DIY prototype of a family house is strategically situated in a former granite quarry in Posázaví, Czech Republic. The primary goal of this project is to assess the structural, typological, and user qualities of the prototype.
Positioned on the edge of a rock overlooking a lake, the house is thoughtfully integrated into the natural environment. It not only preserves existing mature trees but also enhances views of the water and provides access to a central meadow surrounded by forest. The structure itself is a cubic form measuring 15x15x4 meters, within which the interior spaces are intricately designed. These interiors form an organically molded labyrinth that maximizes daylight entry and offers expansive views from deep within the layout.
The house is uniquely supported not by traditional foundations but by a steel load-distributing modular raft that rests on existing granite remnants from the site’s mining past. This non-invasive approach minimizes environmental impact. Constructed atop this raft is a 2×4 timber frame with a nailed trusswork roof structure. The flat roof is topped with extensive greenery, enhancing its integration with the surroundings. The ventilated façade, made of lumber, and aluminum windows contribute to the building’s sustainability.
One of the standout features is a sliding glass wall that seamlessly connects the living area to an outdoor terrace on the meadow, blending indoor and outdoor living spaces. The interior’s monochromatic palette, featuring various shades of white, serves as a neutral backdrop that reflects the changing colors of the forest throughout the seasons.
Uniquely, the house is designed as a DIY kit. It can be disassembled into pieces and removed without leaving any trace, reflecting a deep commitment to environmental stewardship and adaptability. This prototype not only tests innovative building techniques but also showcases a profound respect for its picturesque setting, blending modern living requirements with ecological sensitivity.
