In Alsace, lost amongst the wineyards, it is in the small rural village of Cosswiller that a rather unconventional house can be seen.
Called Héliodome, this unusual green passive house is somewhere between a spinning top and a giant sundial and runs on solar energy.
It is a true technological achievement and a dream come true for its creator Eric Wasser, a cabinetmaker and designer who worked on his project for over 20 years.
