Japanese architect Tadao Ando is restoring an 18th-century stock exchange building in Paris and turning it into a contemporary art gallery.
Exhibition spaces are being built in a circular concrete structure that sits under the historic painted dome of the Bourse de Commerce.

The project is a collaboration between Tadao Ando Architect & Associates, Niney et Marca Architectes, the Pierre-Antoine Gatier architecture agency and building engineering consultant Setec Ba?timent.
French businessman François Pinault, founder of luxury group Kering, commissioned Tadao Ando to transform the heritage building to display some 5,000 artworks he owns.

Built as a corn exchange in 1767 on the site of a demolished mansion, the Bourse de Commerce was turned into a stock market in the mid 1800s.
Murals depicting trade between the five continents of the world dating from the 17th century decorate the underside of the dome.

Ando decided to work with the existing shape of the building to create an internal gallery without disturbing the historic fabric of the building.
"The circular section, faithful to its urban symmetry, includes a rotunda in its centre," said the Japanese architect.
"It is within this rotunda that there has been inserted a concrete cylinder with a diameter of thirty metres and a height of nine metres."
