BONA-81 is a single-storey, flat-roof family house with clean lines, well-proportioned volumes and a clear, functional layout. It continues the minimalist architectural language of the BONA series while offering additional interior space for greater comfort and flexibility. The simple geometry and restrained design allow the house to integrate easily into a wide range of surroundings.

The interior is organised around a generous open living, dining and kitchen area that forms the centre of daily life. Larger room dimensions and improved circulation make the layout suitable for families who value openness and comfort without unnecessary complexity. Bedrooms and bathroom spaces are arranged to provide privacy and practical day-to-day use, while large window openings create a strong connection to the terrace and outdoor areas. The single-level layout ensures easy movement throughout the house and supports long-term usability.

BONA-81 is built using prefabricated timber-frame construction, ensuring precise manufacturing, consistent quality and reliable energy performance. Wall, roof and floor elements are produced in controlled factory conditions, allowing insulation levels, exterior cladding, windows and roof solutions to be adapted to local climate conditions and national building regulations while maintaining the clean architectural character of the model.

The name BONA-81 refers to the net living area of the house. The layout makes efficient use of space, offering a balanced footprint that supports comfortable family living. As with all BONA models, technical specifications can be adjusted depending on location, use and project requirements.

BONA-81 offers a balanced combination of minimalist design and increased living space within a compact, single-storey form. We encourage you to use the configurator to explore available options and get an indicative price. Many additional choices — including colours, finishes and further technical details — can be defined together during the project stage.
