Access to the ground floor was by an opening oriented towards the south. The outer doorway (embrasure), topped by a wooden lintel, was 1.37m. wide and 1.83m. high. As the masonry was about 1m. thick, a succession of inner lintels was necessary.

Access to the 2nd floor was by a raised entry, 2.25m. above ground level and oriented towards the east-south-east. The outer doorway (embrasure) framed in dressed stone, was approximately 1m. wide and 2.51m. high. The outer face of the lintel, now broken was circularly carved. 50 cm. below that, a stone slab formed a transom with the lintel, barred longitudinally by an iron bar. Another stone slab formed the threshold. A wooden staircase and a ladder completed the installation.

The outer facing of the masonry was in regular courses of rubble stone and flat blocks with a dressed outer face. Putlog holes for the scaffolding during original construction are visible at intervals of about 2m. on 3 levels. The primitive roofing of the windmill was probably of the same type as a tower mill, with a conical cap covered with small wooden tiles or flat clay tiles able to be oriented by a long tail or maneuvering lever.

The roof existing in 1990 was a two-sided affair of machine-made tiles supported by a ridge beam oriented to the east-north-east and under each side by two intermediate purlins and an eaves purlin.

The interior organization was probably as follows:

- On the ground floor there was a cellar-warehouse where the donkeys and mules were unloaded.

- The second floor served as living quarters with a fireplace to the north-east and a closet to the north, providing indispensable comfort to temporary inhabitants.

- The third floor must have supported the millstones and the propeller shaft. This second platform no longer existed in 1990, but putlog holes attest to its previous existence. Access was by a staircase of 17 protruding steps set into the wall.

The roof of the Billebaud windmill (named for its pre-1910 owner) fell in in 1994 and the walls continue to deteriorate today. The Society for the Preservation and Enhancement of Saint-Clément-sur-Guye, owner of the ruins and a small plot of land round it since 1994, wishes to save this monument, which represents a historical and architectural interest for the village. In keeping with this purpose, the Association has invited various individuals and organizations to visit the site and the windmill.

The départemental service for architecture and national heritage, through the intervention of Mr. Guillaume, state-appointed architect responsible for the protection of historical monuments, has shown an interest, both for the beauty of the site and for the rarity of the last vestiges of windmills in the Saône-et-Loire. They, too, agree that the windmill should be restored and re-equipped with machinery and vanes.

Mr. Combier, honorary director of research at the CNRS, also supports the project and finds the windmill "admirably placed on a windswept crest overlooking the village and the valley of Vaux-en-Pré" and underlines the fact that most of the windmills of southern Burgundy have disappeared.

In addition to this, since the SIVOM (Syndicat Intercommunal à Vocation Multiple) now become the “Communauté de communes autour du Mont-Saint-Vincent”(grouping of municipalities around Mount Saint-Vincent),committed itself to a plan of rehabilitation, environmentalism and development of the tourist industry, its president, Mr. Girardon, has specified that the restoration of the windmill will be an additional advantage in the development of hiking.

Beyond these encouragements, the aim of the rehabilitation of the Billebaud windmill is to take part in the general community project to develop rural tourism. After the restoration of the village hostel, a project to organize tastings of specific local products is under development. The production of flour, then of bread, in the village is a step in this process of development of local food products. Another purpose of the windmill is to inform school children and tourists of the practices and know-how of former times, allowing them to understand the utility of renewable forms of energy and the interest which they provoke today.
