In 1770 he published a treatise about country houses. He wrote which the houses had to be constructed thinking about the environmental (mountain, hill and plain) and cultural differences; the houses should have built at the center of the farm, with walls to store warmth and a good number of spacious, bright rooms, to be dedicated to domestic life and to work; the external stairs had to be easy and possibly covered "for the part of Tramontane wind" to avoid the frost in winter and defend against any fall.
