The Angolan government has asked Niemeyer, who turns 100 in December, to plan a new city four times the size of Brasília.
The Angolan project would see the construction of a new city, to house 2 million people, on a virgin plot close to the country's current capital, Luanda.
However the nonagenarian, who married his 60-year-old secretary earlier this year, has not yet accepted the commission, claiming he has no desire to travel overseas to carry out the project. - although he suggested he could work on the scheme from his Rio de Janeiro home.
Speaking to the Brazilian press Niemeyer said: 'In reality, it was an invitation from the Angolan authorities, but there is still nothing definite.'
