Top French architects enlisted to transform Paris into a greener and bolder capital city are to unveil their designs, which include a New York style Central Park.

Last year President Nicolas Sarkozy asked ten teams of architects and urban planners to imagine a ‘Grand Paris’, with borders to extend beyond the city’s current two-million residents.

The chosen visionaries include three Pritzker Prize winners: Richard Rogers Jean Nouvel and Christian de Portzamparc.

The selected architects have concluded that most citizens living in the outskirts of the city are cut off from shops, workplaces and the city centre. Paris is home to about two million people, while at least six million more are scattered in nearby suburbs under separate governments.

Plans to create a Central Park area would transform the drab multi-ethnic suburb of La Courneuve, which lies six miles (10km) from the centre of Paris.
